I ka wā o ka "Hoʻolālā ʻElima Makahiki 14", e like me ka hoʻolālā hoʻolālā "carbon peak and carbon neutral" o ka ʻāina, e alakaʻi ka ʻoihana photovoltaic i ka hoʻomohala pahū. ʻO ka hoʻomaka ʻana o ka ʻoihana photovoltaic ua "hoʻokumu i ka waiwai" no ke kaulahao ʻoihana holoʻokoʻa. Ma kēia kaulahao kupaianaha, he loulou koʻikoʻi ke aniani photovoltaic. I kēia lā, e kākoʻo ana i ka mālama ikehu a me ka palekana o ke kaiapuni, ke piʻi nei ke koi no ke aniani photovoltaic i kēlā me kēia lā, a aia kahi kaulike ʻole ma waena o ka lako a me ke koi. I ka manawa like, ua piʻi pū ke one quartz haʻahaʻa a me ke keʻokeʻo loa, kahi mea nui no ke aniani photovoltaic, a ua piʻi ke kumukūʻai a ua nele ka lako. Ua wānana nā loea ʻoihana e loaʻa i ke one quartz haʻahaʻa ka piʻi lōʻihi ma mua o 15% no nā makahiki he 10 a ʻoi. Ma lalo o ka makani ikaika o ka photovoltaic, ua huki nui ka hana ʻana o ke one quartz haʻahaʻa.
1. Ke one Quartz no ke aniani photovoltaic
Hoʻohana nui ʻia ke aniani Photovoltaic ma ke ʻano he panela encapsulation o nā modula photovoltaic, a pili pono ia me ke kaiapuni o waho. ʻO kona kūpaʻa i ka wā, ka ikaika, ka hoʻoili ʻana o ka mālamalama a me nā ʻōkuhi ʻē aʻe e pāʻani i kahi kuleana koʻikoʻi i ke ola o nā modula photovoltaic a me ka pono o ka hana mana lōʻihi. He maʻalahi ke kala ʻana i nā ion hao i loko o ke one quartz, a i mea e hōʻoia ai i ka hoʻoili ʻana o ka lā kiʻekiʻe o ke aniani mua, ʻoi aku ka haʻahaʻa o ka hao o ke aniani photovoltaic ma mua o ke aniani maʻamau, a pono e hoʻohana i ke one quartz haʻahaʻa hao me ka maʻemaʻe silicon kiʻekiʻe a me ka haʻahaʻa o ka haumia.
I kēia manawa, he kakaikahi nā one quartz haʻahaʻa haʻahaʻa kiʻekiʻe e maʻalahi ke eli ʻia ma ko mākou ʻāina, a ua hoʻolaha nui ʻia lākou ma Heyuan, Guangxi, Fengyang, Anhui, Hainan a me nā wahi ʻē aʻe. I ka wā e hiki mai ana, me ka ulu ʻana o ka hiki ke hana i ke aniani i kālai ʻia keʻokeʻo loa no nā cell solar, e lilo ke one quartz kiʻekiʻe me ka wahi hana palena i mea waiwai kakaikahi. ʻO ka lako o ke one quartz kiʻekiʻe a paʻa hoʻi e kaupalena i ka hoʻokūkū o nā hui aniani photovoltaic i ka wā e hiki mai ana. No laila, pehea e hōʻemi pono ai i ka nui o ka hao, alumini, titanium a me nā mea haumia ʻē aʻe i loko o ke one quartz a hoʻomākaukau i ke one quartz maʻemaʻe kiʻekiʻe he kumuhana noiʻi wela.
2. Ka hana ʻana o ke one quartz haʻahaʻa hao no ke aniani photovoltaic
2.1 Hoʻomaʻemaʻe ʻana o ke One Quartz no ke Aniani Photovoltaic
I kēia manawa, ʻo nā kaʻina hana hoʻomaʻemaʻe quartz kuʻuna i hoʻohana pono ʻia i ka ʻoihana e komo pū ana me ka hoʻokaʻawale ʻana, ka holoi ʻana, ka hoʻopau ʻana i ka calcination-wai, ka wili ʻana, ka sieving, ka hoʻokaʻawale magnetic, ka hoʻokaʻawale umekaumaha, ka flotation, ka leaching acid, ka leaching microbial, ka degassing wela kiʻekiʻe, a pēlā aku. ʻO nā kaʻina hana hoʻomaʻemaʻe hohonu e komo pū ana me ka chlorinated roasting, ka hoʻokaʻawale kala irradiated, ka hoʻokaʻawale magnetic superconducting, ka vacuum wela kiʻekiʻe a pēlā aku. Ua hoʻomohala ʻia ke kaʻina hana hoʻomaikaʻi maʻamau o ka hoʻomaʻemaʻe one quartz home mai ka "wili ʻana, ka hoʻokaʻawale magnetic, ka holoi ʻana" mua a hiki i ka "hoʻokaʻawale → ka wāwahi nui → calcination → ka hoʻopau ʻana i ka wai → ka wili ʻana → ka nānā ʻana → ka hoʻokaʻawale magnetic → ka flotation → acid ʻO ke kaʻina hana hoʻomaikaʻi i hui pū ʻia o ka hoʻokomo ʻana → ka holoi → ka maloʻo ʻana, i hui pū ʻia me ka microwave, ultrasonic a me nā ʻano ʻē aʻe no ka pretreatment a i ʻole ka hoʻomaʻemaʻe kōkua, hoʻomaikaʻi nui i ka hopena hoʻomaʻemaʻe. Ma muli o nā koi haʻahaʻa hao o ke aniani photovoltaic, ua hoʻolauna nui ʻia ka noiʻi a me ka hoʻomohala ʻana i nā ʻano wehe one quartz.
Ma keʻano laulā, aia ka hao ma nā ʻano ʻeono maʻamau i loko o ka quartz ore:
① Loaʻa ma ke ʻano o nā ʻāpana liʻiliʻi i loko o ka pālolo a i ʻole kaolinized feldspar
②Hoʻopili ʻia i ka ʻili o nā ʻāpana quartz ma ke ʻano o ka ʻili hao oxide
③Nā minelala hao e like me ka hematite, magnetite, specularite, qinite, a pēlā aku a i ʻole nā minelala hao e like me ka mica, amphibole, garnet, a pēlā aku.
④Aia i loko o ke kūlana o ka hoʻoluʻu ʻana a i ʻole ka lens i loko o nā ʻāpana quartz
⑤ Aia i loko o ke kūlana o ka hopena paʻa i loko o ke aniani quartz
⑥ E hui pū ʻia kekahi nui o ka hao lua i ke kaʻina hana kuʻi a me ka wili ʻana
I mea e hoʻokaʻawale pono ai i nā minelala hao mai ka quartz, pono mua e ʻike i ke ʻano o nā haumia hao i loko o ka ore quartz a koho i kahi ʻano hoʻomaikaʻi kūpono a me ke kaʻina hana hoʻokaʻawale e hoʻopau ai i nā haumia hao.
(1) Kaʻina hana hoʻokaʻawale magnetic
Hiki i ke kaʻina hana hoʻokaʻawale magnetic ke wehe i nā minelala haumia magnetic nāwaliwali e like me ka hematite, limonite a me ka biotite me nā ʻāpana i hui pū ʻia i ka nui loa. Wahi a ka ikaika magnetic, hiki ke hoʻokaʻawale ʻia ka hoʻokaʻawale magnetic i ka hoʻokaʻawale magnetic ikaika a me ka hoʻokaʻawale magnetic nāwaliwali. ʻO ka hoʻokaʻawale magnetic ikaika e hoʻohana pinepine i ka hoʻokaʻawale magnetic ikaika pulu a i ʻole ka hoʻokaʻawale magnetic gradient kiʻekiʻe.
Ma ke ʻano laulā, hiki ke koho ʻia ke one quartz e loaʻa ana nā minelala haumia magnetic nāwaliwali e like me ka limonite, hematite, biotite, a me nā mea ʻē aʻe, me ka hoʻohana ʻana i kahi mīkini magnetic ikaika ʻano pulu ma kahi waiwai ma luna o 8.0 × 105A / m; No nā minelala magnetic ikaika i hoʻomalu ʻia e ka hao hao, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i kahi mīkini magnetic nāwaliwali a i ʻole kahi mīkini magnetic waena no ka hoʻokaʻawale ʻana. [2] I kēia mau lā, me ka hoʻohana ʻana o nā mea hoʻokaʻawale magnetic kiʻekiʻe a me ke kahua magnetic ikaika, ua hoʻomaikaʻi nui ʻia ka hoʻokaʻawale magnetic a me ka hoʻomaʻemaʻe ʻana i hoʻohālikelike ʻia me ka wā ma mua. No ka laʻana, ʻo ka hoʻohana ʻana i kahi mea hoʻokaʻawale magnetic ikaika ʻano roller induction electromagnetic e wehe i ka hao ma lalo o ka ikaika o ke kahua magnetic 2.2T hiki ke hōʻemi i ka ʻike o Fe2O3 mai 0.002% a i 0.0002%.
(2) Ke kaʻina hana lana
ʻO ka flotation kahi hana o ka hoʻokaʻawale ʻana i nā ʻāpana mineral ma o nā ʻano kino a me nā kemika like ʻole ma luna o ka ʻili o nā ʻāpana mineral. ʻO ka hana nui ka wehe ʻana i ka mineral mica a me ka feldspar e pili ana mai ke one quartz. No ka hoʻokaʻawale ʻana o ka flotation o nā mineral hao a me ka quartz, ʻo ka ʻike ʻana i ke ʻano o ka haumia hao a me ke ʻano hoʻolaha o kēlā me kēia nui o ka ʻāpana ke kī i ke koho ʻana i kahi hana hoʻokaʻawale kūpono no ka wehe ʻana i ka hao. ʻO ka hapa nui o nā mineral hao he zero electric point ma luna o 5, kahi i hoʻopiʻi maikaʻi ʻia i loko o kahi ʻano acidic, a kūpono hoʻi no ka hoʻohana ʻana i nā mea hōʻiliʻili anionic.
Hiki ke hoʻohana ʻia ka waikawa momona (kopa), hydrocarbyl sulfonate a i ʻole sulfate ma ke ʻano he mea hōʻiliʻili anionic no ka flotation o ka hao oxide ore. Hiki ke hoʻokahe ʻia ka Pyrite o ka pyrite mai ka quartz i loko o kahi ʻano pickling me ka mea flotation maʻamau no ka isobutyl xanthate me ka pauka ʻeleʻele butylamine (4:1). ʻO ka dosage ma kahi o 200ppmw.
ʻO ka hoʻoluʻu ʻana o ka ilmenite ma ke ʻano he mea hoʻoluʻu e hoʻoponopono i ka pH i 4 ~ 10. Hana ʻia kahi hopena kemika ma waena o nā ion oleate a me nā ʻāpana hao ma luna o ka ʻili o ka ilmenite e hana i ka hao oleate, kahi i hoʻopili ʻia e nā kemika. Mālama nā ion Oleate i ka ilmenite me ka lana maikaʻi. ʻO nā mea hōʻiliʻili waikawa phosphonic i hoʻokumu ʻia i ka hydrocarbon i hoʻomohala ʻia i nā makahiki i hala iho nei he koho maikaʻi a me ka hana hōʻiliʻili no ka ilmenite.
(3) Ke kaʻina hana hoʻoheheʻe ʻakika
ʻO ke kumu nui o ke kaʻina hana hoʻoheheʻe waikawa, ʻo ia ka wehe ʻana i nā minelala hao hiki ke hoʻoheheʻe ʻia i loko o ka hopena waikawa. ʻO nā mea e hoʻopilikia ai i ka hopena hoʻomaʻemaʻe o ka hoʻoheheʻe waikawa e komo pū ana me ka nui o nā ʻāpana one quartz, ka mahana, ka manawa, ke ʻano waikawa, ka nui o ka waikawa, ka lakio paʻa-wai, a me nā mea ʻē aʻe, a hoʻonui i ka mahana a me ka hopena waikawa. ʻO ka hoʻohuihui ʻana a me ka hoʻemi ʻana i ka radius o nā ʻāpana quartz hiki ke hoʻonui i ka nui o ka hoʻoheheʻe ʻana a me ka nui o ka hoʻoheheʻe ʻana o Al. He palena ka hopena hoʻomaʻemaʻe o kahi waikawa hoʻokahi, a he hopena synergistic ka waikawa i hui ʻia, hiki ke hoʻonui nui i ka nui o ka wehe ʻana o nā mea haumia e like me Fe a me K. ʻO nā waikawa inorganic maʻamau ʻo HF, H2SO4, HCl, HNO3, H3PO4, HClO4, H2C2O4, ma ke ʻano laulā ʻelua a ʻoi aku paha o lākou i hui pū ʻia a hoʻohana ʻia i kahi ʻāpana.
ʻO ka waikawa Oxalic kahi waikawa organik i hoʻohana pinepine ʻia no ka hoʻoheheʻe ʻana o ka waikawa. Hiki iā ia ke hana i kahi paʻakikī paʻa me nā ion metala i hoʻoheheʻe ʻia, a maʻalahi ka holoi ʻana i nā mea haumia. Loaʻa iā ia nā pono o ka haʻahaʻa haʻahaʻa a me ka wikiwiki wehe hao kiʻekiʻe. Hoʻohana kekahi poʻe i ka ultrasound e kōkua i ka hoʻomaʻemaʻe ʻana o ka waikawa oxalic, a ua ʻike ʻia i ka hoʻohālikelike ʻana me ka hoʻoulu maʻamau a me ka ultrasound tank, ʻo ka ultrasound probe ka wikiwiki wehe Fe kiʻekiʻe loa, ʻo ka nui o ka waikawa oxalic ma lalo o 4g/L, a hiki i ka wikiwiki wehe hao i 75.4%.
Hiki i ke alo o ka waikawa dilute a me ka waikawa hydrofluoric ke hoʻopau pono i nā haumia metala e like me Fe, Al, Mg, akā pono e kāohi ʻia ka nui o ka waikawa hydrofluoric no ka mea hiki i ka waikawa hydrofluoric ke hōʻino i nā ʻāpana quartz. Hoʻopilikia pū ka hoʻohana ʻana i nā ʻano waikawa like ʻole i ka maikaʻi o ke kaʻina hana hoʻomaʻemaʻe. I waena o lākou, ʻo ka waikawa hui ʻia o HCl a me HF ka hopena hana maikaʻi loa. Hoʻohana kekahi poʻe i ka mea hoʻoheheʻe hui ʻia ʻo HCl a me HF e hoʻomaʻemaʻe i ke one quartz ma hope o ka hoʻokaʻawale magnetic. Ma o ka hoʻoheheʻe kemika, ʻo ka nui o nā mea haumia he 40.71μg/g, a ʻo ka maʻemaʻe o SiO2 he 99.993wt%.
(4) Ka hoʻokahe ʻana o nā microbial
Hoʻohana ʻia nā microorganisms no ka hoʻoheheʻe ʻana i ka hao ʻili lahilahi a i ʻole ka hoʻokomo ʻana i ka hao ma luna o ka ʻili o nā ʻāpana one quartz, he ʻano hana i hoʻomohala hou ʻia no ka wehe ʻana i ka hao. Ua hōʻike ʻia nā noiʻi haole ua loaʻa nā hopena maikaʻi i ka hoʻohana ʻana iā Aspergillus niger, Penicillium, Pseudomonas, Polymyxin Bacillus a me nā microorganisms ʻē aʻe i ka hoʻoheheʻe ʻana i ka hao ma luna o ka ʻili o ka ʻili quartz, kahi i loaʻa ai ka hopena maikaʻi loa o ka Aspergillus niger leaching iron. ʻOi aku ka nui o ka helu wehe ʻana o Fe2O3 ma mua o 75%, a ʻo ka pae o ka Fe2O3 concentrate he haʻahaʻa e like me 0.007%. A ua ʻike ʻia ʻoi aku ka maikaʻi o ka hopena o ka hoʻoheheʻe ʻana i ka hao me ka mahi mua ʻana o ka hapa nui o nā bacteria a me nā ʻōpala.
2.2 Ke holomua noiʻi ʻē aʻe o ke one quartz no ke aniani photovoltaic
I mea e hōʻemi ai i ka nui o ka waikawa, e hōʻemi i ka paʻakikī o ka mālama ʻana i ka wai ʻino, a e launa pū me ke kaiapuni, ua hōʻike ʻo Peng Shou [5] et al. i kahi ʻano hana no ka hoʻomākaukau ʻana i ke one quartz haʻahaʻa hao 10ppm ma o kahi hana ʻole pickling: hoʻohana ʻia ka quartz vein maoli ma ke ʻano he mea maka, a me ka wāwahi ʻekolu-paepae, ʻO ka wili ʻana o ke kahua mua a me ka hoʻokaʻawale ʻana o ke kahua ʻelua e loaʻa ai ka grit 0.1 ~ 0.7mm; hoʻokaʻawale ʻia ka grit e ke kahua mua o ka hoʻokaʻawale magnetic a me ke kahua ʻelua o ka wehe ʻana i ka magnetic ikaika o ka hao mechanical a me nā mineral hao e loaʻa ai ke one hoʻokaʻawale magnetic; loaʻa ka hoʻokaʻawale magnetic o ke one ma o ka flotation ʻana o ke kahua ʻelua ʻOi aku ka haʻahaʻa o ka ʻike Fe2O3 ma mua o 10ppm one quartz haʻahaʻa hao, hoʻohana ka flotation iā H2SO4 ma ke ʻano he mea hoʻoponopono, hoʻoponopono i ka pH = 2 ~ 3, hoʻohana i ka sodium oleate a me ka propylene diamine i hoʻokumu ʻia i ka ʻaila niu ma ke ʻano he mea hōʻiliʻili. ʻO ke one quartz i hoʻomākaukau ʻia ʻo SiO2≥99.9%, Fe2O3≤10ppm, e hoʻokō i nā koi o nā mea maka siliceous e pono ai no ke aniani optical, ke aniani hōʻike photoelectric, a me ke aniani quartz.
Ma ka ʻaoʻao ʻē aʻe, me ka emi ʻana o nā kumuwaiwai quartz kiʻekiʻe, ua huki ka hoʻohana piha ʻana i nā kumuwaiwai haʻahaʻa i ka manaʻo nui. Ua hoʻohana ʻo Xie Enjun o China Building Materials Bengbu Glass Industry Design and Research Institute Co., Ltd. i nā ʻōpala kaolin e hoʻomākaukau i ke one quartz hao haʻahaʻa no ke aniani photovoltaic. ʻO ka mineral nui o nā ʻōpala kaolin Fujian he quartz, nona ka liʻiliʻi o nā mineral haumia e like me ka kaolinite, mica, a me ka feldspar. Ma hope o ka hana ʻia ʻana o nā ʻōpala kaolin e ke kaʻina hana beneficiation o ka "wili-hydraulic classification-magnetic separation-flotation", ʻoi aku ka nui o ka nui o ka ʻāpana 0.6 ~ 0.125mm ma mua o 95%, ʻo SiO2 he 99.62%, ʻo Al2O3 he 0.065%, ʻo Fe2O3 he 92 × 10-6 one quartz maikaʻi e hoʻokō i nā koi maikaʻi o ke one quartz hao haʻahaʻa no ke aniani photovoltaic.
Ua paʻi ʻo Shao Weihua a me nā poʻe ʻē aʻe mai ka Zhengzhou Institute of Comprehensive Utilization of Mineral Resources, Chinese Academy of Geological Sciences, i kahi palapala hoʻopaʻa inoa i hana ʻia: he ʻano hana no ka hoʻomākaukau ʻana i ke one quartz maʻemaʻe kiʻekiʻe mai nā tailings kaolin. ʻO nā ʻanuʻu hana: a. Hoʻohana ʻia nā tailings Kaolin ma ke ʻano he ore maka, kahi i kānana ʻia ma hope o ka hoʻoulu ʻia a me ka holoi ʻana e loaʻa ai ka mea +0.6mm; b. Kuʻi ʻia a hoʻokaʻawale ʻia ka mea +0.6mm, a ua hoʻokomo ʻia ka mea mineral 0.4mm0.1mm i ka hana hoʻokaʻawale magnetic, No ka loaʻa ʻana o nā mea magnetic a me nā mea ʻole-magnetic, komo nā mea ʻole-magnetic i ka hana hoʻokaʻawale umekaumaha e loaʻa ai nā minelala māmā hoʻokaʻawale umekaumaha a me nā minelala kaumaha hoʻokaʻawale umekaumaha, a komo nā minelala māmā hoʻokaʻawale umekaumaha i ka hana regrind e pale e loaʻa ai nā minelala +0.1mm; c.+0.1mm Komo ka mineral i ka hana flotation e loaʻa ai ka flotation concentrate. Wehe ʻia ka wai o luna o ka flotation concentrate a laila pickled ultrasonically, a laila kānana ʻia e loaʻa ai ka mea coarse +0.1mm e like me ke one quartz maʻemaʻe kiʻekiʻe. ʻAʻole hiki i ke ʻano o ka mea i hana ʻia ke loaʻa wale nā huahana quartz kiʻekiʻe, akā he manawa hana pōkole hoʻi, ke kahe hana maʻalahi, ka hoʻohana ʻana i ka ikehu haʻahaʻa, a me ke kūlana kiʻekiʻe o ka quartz concentrate i loaʻa, hiki ke hoʻokō i nā koi maikaʻi o ka quartz maʻemaʻe kiʻekiʻe.
Loaʻa i nā ʻōpala Kaolin ka nui o nā kumuwaiwai quartz. Ma o ka hoʻomaikaʻi ʻana, ka hoʻomaʻemaʻe ʻana a me ka hana hohonu ʻana, hiki iā ia ke hoʻokō i nā koi no ka hoʻohana ʻana i nā mea maka aniani keʻokeʻo photovoltaic. Hāʻawi pū kēia i kahi manaʻo hou no ka hoʻohana piha ʻana i nā kumuwaiwai ʻōpala kaolin.
3. ʻIke mākeke o ke one quartz haʻahaʻa hao no ke aniani photovoltaic
Ma kekahi ʻaoʻao, i ka hapa lua o 2020, ʻaʻole hiki i ka mana hana i kaupalena ʻia e ka hoʻonui ʻana ke hoʻokō i ke koi pahū ma lalo o ka pōmaikaʻi nui. ʻAʻole kaulike ka lako a me ke koi o ke aniani photovoltaic, a ke piʻi nei ke kumukūʻai. Ma lalo o ke kāhea hui o nā ʻoihana modula photovoltaic he nui, i Dekemaba 2020, ua hoʻopuka ke Kuhina o ka ʻOihana a me ka ʻIke ʻIke i kahi palapala e wehewehe ana ʻaʻole paha e hoʻokumu ka papahana aniani ʻōwili photovoltaic i kahi hoʻolālā pani mana. Ma muli o ka hoʻopilikia ʻia e ke kulekele hou, e hoʻonui ʻia ka ulu ʻana o ka hana aniani photovoltaic mai 2021. Wahi a ka ʻike lehulehu, ʻo ka hiki o ke aniani photovoltaic i ʻōwili ʻia me kahi hoʻolālā maopopo no ka hana ʻana ma 21/22 e hiki i ka 22250/26590t/d, me ka ulu makahiki o 68.4/48.6%. I ke ʻano o nā kulekele a me nā hōʻoia koi, manaʻo ʻia ke one photovoltaic e hoʻolauna i ka ulu pahū.
Ka mana hana o ka ʻoihana aniani photovoltaic 2015-2022
Ma ka ʻaoʻao ʻē aʻe, ʻo ka hoʻonui nui ʻana o ka hiki ke hana o ke aniani photovoltaic e hoʻonui paha i ka lako o ke one silica haʻahaʻa hao ma mua o ka lako, kahi e kaupalena ai i ka hana maoli o ka hiki ke hana aniani photovoltaic. Wahi a nā helu helu, mai ka makahiki 2014, ʻoi aku ka haʻahaʻa o ka hana one quartz kūloko o koʻu ʻāina ma mua o ke koi kūloko, a ua mālama ka lako a me ke koi i kahi kaulike paʻa.
I ka manawa like, ua kakaikahi nā kumuwaiwai placer quartz haʻahaʻa hao kūloko o koʻu ʻāina, i hoʻopaʻa ʻia ma Heyuan o Guangdong, Beihai o Guangxi, Fengyang o Anhui a me Donghai o Jiangsu, a pono e lawe ʻia mai kahi nui o lākou.
ʻO ke one quartz keʻokeʻo haʻahaʻa haʻahaʻa kekahi o nā mea maka koʻikoʻi (e helu ana ma kahi o 25% o ke kumukūʻai o nā mea maka) i nā makahiki i hala iho nei. Ke piʻi nei hoʻi ke kumukūʻai. I ka wā ma mua, aia ma kahi o 200 yuan/ton no ka manawa lōʻihi. Ma hope o ka hoʻomaka ʻana o ke ahulau Q1 i loko o 20 mau makahiki, ua hāʻule ia mai kahi pae kiʻekiʻe, a ke mālama nei i ka hana paʻa no kēia manawa.
I ka makahiki 2020, ʻo ka nui o ke koi o koʻu ʻāina no ke one quartz he 90.93 miliona tons, ʻo ka hana he 87.65 miliona tons, a ʻo ka lawe ʻia mai he 3.278 miliona tons. Wahi a ka ʻike lehulehu, ʻo ka nui o ka pōhaku quartz i loko o 100kg o ke aniani heheʻe ma kahi o 72.2kg. Wahi a ka hoʻolālā hoʻonui o kēia manawa, hiki i ka hoʻonui ʻana o ka mana o ke aniani photovoltaic i ka makahiki 2021/2022 ke hiki i ka 3.23/24500t/d, e like me ka hana makahiki. I helu ʻia ma luna o kahi manawa 360 lā, e kūlike ka hana holoʻokoʻa me ke koi hou i hoʻonui ʻia no ke one silica haʻahaʻa hao o 836/635 miliona tons/makahiki, ʻo ia hoʻi, ʻo ke koi hou no ke one silica haʻahaʻa hao i lawe ʻia mai e ke aniani photovoltaic i ka makahiki 2021/2022 e helu no ke one quartz holoʻokoʻa i ka makahiki 2020 9.2%/7.0% o ke koi. Ke noʻonoʻo nei ʻo ke one silica haʻahaʻa hao wale nō ka hapa o ke koi o ke one silica holoʻokoʻa, ʻo ke kaomi o ka lako a me ke koi ma ke one silica haʻahaʻa hao i hoʻokumu ʻia e ka hoʻopukapuka nui ʻana o ka hiki ke hana aniani photovoltaic e ʻoi aku paha ke kiʻekiʻe ma mua o ke kaomi ma ka ʻoihana one quartz holoʻokoʻa.
