【ʻIke Mining】 Pono ka hoʻohana ʻana i nā kumuwaiwai o nā huelo gula

ʻO ka hoʻohana piha ʻana i nā huelo he huaʻōlelo wela i ka mahina ʻai i nā makahiki i hala iho nei, a ua hana ʻia ka noiʻi ʻana i ka hoʻohana piha ʻana i nā huelo gula.Ua hoʻomaopopo ʻia ʻo ka hana ʻana o nā huelo mine gula ma koʻu ʻāina ua hiki aku ma mua o 1.5 biliona tons, akā ʻoi aku ka nui o ka hoʻohana ʻana ma lalo o 20%. ʻElua mau ala o kaʻu huelo: ʻo ka hoʻopiha ʻana i lalo a me ka hoʻohana ʻana i nā kumuwaiwai. ʻO ke kaʻina hana hoʻopiha maʻamau o nā mines gula ʻo ia ka hoʻopiha ʻana i nā huelo ʻōpala i loko o ka pūnāwai, ʻoiai ʻo nā huelo maikaʻi e hōʻiliʻili ʻia i loko o ka loko huelo. ʻO ka mea maʻamau ka haʻahaʻa, i mea e hoʻonui ai i ka loaʻa ʻana o nā kumuwaiwai gula, pono maʻamau ka hana ʻana i nā hana wili.No laila, he nui nā huelo maikaʻi, ʻoiai ʻoi aku ka liʻiliʻi o nā huelo koʻikoʻi, a ʻo nā huelo koʻikoʻi wale nō i hoʻopiha ʻia ma lalo o ka lepo., ʻaʻole hiki ke hoʻemi maoli i ka ʻōpala paʻa a hoʻemi i ka hiki ke mālama i nā loko huelo.ʻO ka mālama ʻana i nā loko huelo he mea nui ka ʻāina a me ka pōʻino i ke kaiapuni.

Ma Pepeluali 10, 2022, ka Ministry of Industry and Information Technology, ka National Development and Reform Commission, ka Ministry of Science and Technology, ke Kuhina Waiwai, ka Ministry of Natural Resources, ka Ministry of Ecology and Environment, the Ministry of Commerce. , a me ka State Administration of Taxation i hoʻopuka pū i ka "On Printing and Distributing Accelerating the Promotion of Industrial Resources".Pono ka "Notice on the Implementation Plan for Comprehensive Utilization" e hiki i ka makahiki 2025, e emi iho ka ikaika o ka hana ʻōpala paʻa paʻa i nā ʻoihana nui e like me ka hao a me ke kila, nā metala non-ferrous, a me nā ʻoihana kemika ma koʻu ʻāina, e emi ana ka pae hoʻohana piha. e hoʻomaikaʻi maikaʻi ʻia ka ʻōpala paʻa ʻoihana nui, e hoʻomau maikaʻi ʻia ka ʻoihana waiwai hou, a e hoʻohana nui ʻia nā kumuwaiwai ʻoihana.Ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi, a ʻo ka nui o ka hoʻohana ʻana i nā ʻōpala paʻa ʻoihana nui e hiki i 57%.

ʻO ka Sino-German Key Laboratory of Magnetoelectricity and Intelligent Mineral Processing of Huate Company e alakaʻi i ka nui o nā hoʻokolohua pōmaikaʻi ma nā huelo gula ma Yantai wahi.ʻO nā mea koʻikoʻi koʻikoʻi o nā huelo gula he mau mineral gangue e like me ka quartz, feldspar a me ka calcite, a me kahi mea liʻiliʻi o ka mechanical Iron, magnetic iron, iron oxide, titanium oxide, iron silicate, iron sulfide a me nā mea haumia ʻē aʻe. ʻO nā huelo gula ma ke ʻano he 200 mesh 50-70%, ʻano like ka nui o ka ʻāpana, a loaʻa kahi liʻiliʻi o ka lepo maikaʻi.ʻO ka maʻiʻo Fe2O3 haumia nui he 1-3%, he 0.1-0.3% ka TiO2, he 0.12-1.0% ka CaO, a he 5-20% ke keʻokeʻo o nā hue gula.Aia kekahi mau ʻokoʻa i ka haku ʻana o nā huelo i hana ʻia e nā concentrators like ʻole.ʻO kekahi mau huelo he kiʻekiʻe ka SiO2 maʻiʻo, a i ʻole spodumene, sericite, etc. ʻO ka hapa nui o lākou no ka feldspar-quartz type pegmatite type, me ka waiwai hoʻohana hou.

Huate Company invented the "magnetic separation-gravity separation" hui beneficiation kaʻina, a loaʻa i ka noʻonoʻo patent mana i loko o Kepakemapa 2020. ʻO ka maʻiʻo patent e pili ana i "kahi hana hoʻohana piha o nā huelo gula i loaʻa i ke gula, hao a me feldspar. He ʻumi mau hana ʻoihana nui i hana ʻia ma Yantai, Shandong, ʻo ka mea nui loa e hiki ke hana i 8,000 tons o nā huelo gula i kēlā me kēia lā. , pulu ka mea hoʻokaʻawale mākēneki pākuʻi ikaika, apo hoʻokalakupua kiʻekiʻe gradient magnetic separator, a hoʻohana pū ʻia ka electromagnetic slurry magnetic separator.ʻOiai ka loaʻa ʻana o ka feldspar concentrate kiʻekiʻe mai nā huelo, ua hoʻihoʻi hou ʻia nā huahana waiwai e like me ka magnetite, nā minerala gula, nā kumu sima, a me nā mea hana brick-maker no ka hoʻomaopopo ʻana i ka hoʻohana piha ʻana i nā huelo gula a loaʻa i ka hoʻokuʻu ʻole ʻana i nā mea āpau. - ala puni.

Hoʻohana ʻia ke apo vertical gradient magnetic separator kiʻekiʻe a me ka electromagnetic slurry high gradient magnetic separator i ka papahana huelo gula.
