ʻO nā minelala e pili ana i ka titanium ka ilmenite, rutile, anatase, brookite, perovskite, sphene, titanomagnetite, a me nā mea ʻē aʻe, ʻo ia hoʻi ka ilmenite a me ka rutile nā minelala hoʻoheheʻe titanium nui.
ʻO ke ʻano molekala o ka ilmenite ʻo FeTiO3, aia ma ke kumumanaʻo he 52.66% o TiO2 a me 47.34% o FeO. He ʻano kila hina a ʻeleʻele paha ia, me ka paʻakikī Mohs o 5-6, ka nui o 4.72g/cm3, ka magnetism waena, ke alakaʻi maikaʻi, a me ke ʻano maʻamau. Hoʻohui ʻia ke ʻano qualitative me ka magnesium a me ka manganese, a i ʻole he mau inclusions hematite scaly maikaʻi.
ʻO ke ʻano molekala o ka rutile ʻo TiO2, nona ka 60% Ti a me 40% O. He mineral ʻulaʻula-ʻeleʻele ia, pinepine i ka hui ʻana o ka hao, niobium, chromium, tantalum, tin, a me nā mea ʻē aʻe, me ka paʻakikī Mohs o 6, a me ka nui o 4.2 ~ 4.3g / cm3. Magnetism, conductivity maikaʻi, ʻeleʻele ʻeleʻele ke kiʻekiʻe ka nui o ka hao, hana nui ʻia ka rutile ma nā placers.
Nā kahua noi a me nā ʻōkuhi loea
ʻO Rutile a me ilmenite nā mea maka nui no ka hoʻoheheʻe ʻana i ka titanium metala, ka hana ʻana i ka titanium dioxide, nā koʻokoʻo kuʻihao, a me nā flux kuʻihao.

ʻenehana hana
ʻO ka maʻamau, hele pū ʻia ka ilmenite a me ka rutile ore me nā ʻano minelala like ʻole, e like me ka magnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene. ʻO nā pōhaku, a me nā mea ʻē aʻe, i koho pinepine ʻia e ka hoʻokaʻawale ʻana o ka umekaumaha, ka hoʻokaʻawale magnetic, ka hoʻokaʻawale uila a me ka flotation.
Ka hoʻomaikaʻi ʻana i ka umekaumaha
Hoʻohana nui ʻia kēia ʻano hana no ka hoʻokaʻawale ʻana i ka mea hoʻonoho titanium a i ʻole ka ʻaila mua i hoʻopaʻa ʻia me ka titanium. ʻOi aku ka nui o nā minelala i loaʻa ka titanium ma mua o 4g/cm3. No laila, hiki ke wehe ʻia ka hapa nui o nā gangues me ka nui ma lalo o 3g/cm3 e ka hoʻokaʻawale ʻana i ka umekaumaha. Wehe mineral. ʻO nā lako hoʻokaʻawale umekaumaha e komo pū me ka jig, spiral concentrator, shaker, chute, a pēlā aku.
Ka hoʻokaʻawale magnetic
Hoʻohana nui ʻia ke ʻano hoʻokaʻawale magnetic i ke koho ʻana i nā minelala i loaʻa ka titanium. Hiki iā mākou ke hoʻohana i ka hoʻokaʻawale magnetic nāwaliwali e hoʻokaʻawale i ka magnetite, a laila e hoʻohana i ka hoʻokaʻawale magnetic ikaika e hoʻokaʻawale i ka ilmenite magnetic waena. No ka laʻana, ʻoi aku ka nui o ka oxide hao i loko o ka concentrate a i ʻole No ka silicate hao, pono e hoʻohana ʻia ke ʻano hoʻokaʻawale umekaumaha e wehe i nā haumia me kahi umekaumaha kikoʻī liʻiliʻi. I ka ʻoihana, hoʻohana ʻia ka hoʻokaʻawale magnetic maloʻo a me ka pulu. ʻO nā lako hoʻokaʻawale magnetic e komo pū me ka hoʻokaʻawale magnetic cylindrical, ka hoʻokaʻawale magnetic plate, ka hoʻokaʻawale magnetic gradient kiʻekiʻe apo vertical, a pēlā aku.
Ka mea hoʻokaʻawale makeneka pahu
Ka mea hoʻokaʻawale magnetic papa magnetic ikaika kiʻekiʻe
Ka hoʻomaikaʻi ʻana i ka electrostatic
Hoʻohana nui ia i ka ʻokoʻa o ka conductivity ma waena o nā minelala like ʻole i loko o ka titanium-concentrate coarse no ke koho ʻana, e like me ka hoʻokaʻawale ʻana o ka rutile, zircon, a me ka monazite. ʻO nā mea hoʻokaʻawale uila i hoʻohana ʻia he ʻano roller, ʻano plate, ʻano sieve plate a pēlā aku.
Lana ʻana
Hoʻohana nui ʻia ia e hoʻokaʻawale i ka ʻaihao titanium maikaʻi. ʻO nā mea hana flotation i hoʻohana pinepine ʻia e komo pū me ka waikawa sulfuric, ka ʻaila kiʻekiʻe, ka waikawa oleic, ka ʻaila diesel a me nā emulsifiers. ʻO nā ʻano hana hoʻomaikaʻi e komo pū me ka flotation maikaʻi o ka titanium a me ka flotation hoʻohuli o nā minelala gangue.
Hoʻomaikaʻi like ʻana
No ka placerite me nā minelala pili hou aku, hiki ke hoʻohana ʻia ka ʻokoʻa o ka susceptibility magnetic kikoʻī, ka nui, ka conductivity, a me ka floatability ma waena o nā minelala e hoʻokaʻawale i nā minelala ma o ke kaʻina hana hui pū ʻia o "magnetic, heavy, electric, and float". No ka laʻana, aia nā minelala e like me magnetite, ilmenite, rutile, zircon one, monazite, sea one, etc. ʻO ka mua, hoʻokaʻawale ʻia ka magnetite e ke kahua magnetic nāwaliwali, a laila hoʻokaʻawale ʻia ka ilmenite e ke apo kū pololei me ka ikaika kahua waena. ʻO ke apo kū pololei ikaika kahua kiʻekiʻe o nā tailings apo kū pololei e wehe i nā minelala hao ʻē aʻe, a laila hoʻokaʻawale ʻia ka umekaumaha kikoʻī liʻiliʻi e ke ʻano hoʻokaʻawale umekaumaha. No ke one kai, ʻo nā minelala kaumaha he rutile a me ke one zircon. Hiki ke koho ʻia ka rutile me ka conductivity maikaʻi aʻe e ka hoʻokaʻawale uila, i mea e hoʻopau ai i ka hoʻokaʻawale pono ʻana o kēia ʻano minelala.
Ka mea hoʻokaʻawale makeneka gradient kiʻekiʻe o ke apo kū pololei
Hihia hoʻopōmaikaʻi
Aia ka magnetite, titanomagnetite, ilmenite, rutile, one zircon, one kai a me kahi liʻiliʻi o nā minelala hao i nā mea hoʻonoho alluvial ma Indonesia.，I waena o lākou, ʻo ka ilmenite, rutile, a me ke one zircon nā minelala nui i manaʻo ʻia, a ʻo ka titanomagnetite, ka hao oxide, ka hao silicate, a me ke one kai he mau haumia. Hoʻokaʻawale ʻia a hoʻomaʻamaʻa ʻia nā minelala e nā ʻano kino e like me ka hoʻokaʻawale magnetic a me ka hoʻokaʻawale umekaumaha. ʻO nā huahana concentrate āpau. I waena o lākou, ʻo ka ilmenite, rutile, zircon nā minelala nui i manaʻo ʻia, ilmenite, hao oxide, hao silicate, ke one kai e like me nā haumia, Ma o ka hoʻokaʻawale magnetic, ka hoʻokaʻawale umekaumaha a me nā ʻano kino ʻē aʻe, hoʻokaʻawale ʻia nā minelala a koho ʻia nā huahana concentrate kūpono.
ʻO ka nui o nā ʻāpana o ke one alluvial he like, a ʻo ka nui o nā ʻāpana maʻamau he 0.03 ~ 0.85 mm. ʻO nā huahana concentrate kūpono e like me ka ilmenite, rutile a me ke one zircon e hoʻokaʻawale ʻia e ke kaʻina hana beneficiation i hui pū ʻia o ka hoʻokaʻawale magnetic nāwaliwali + ka hoʻokaʻawale magnetic waena + ka hoʻokaʻawale magnetic kiʻekiʻe + ka hoʻokaʻawale umekaumaha.
- Ua hōʻike ʻia ka helu kuhikuhi pōmaikaʻi ma ka Papa 4.
Kiʻi 1. Kaʻina hana hoʻāʻo hoʻomaikaʻi hui pū ʻia o ka ʻaila one alluvial
Papa 4. Nā Kuhikuhi o ka Hoʻāʻo Pōmaikaʻi Hui
Ma ka hoʻohana ʻana i ka ʻokoʻa o ka susceptibility magnetic kikoʻī a me ka density ma waena o nā minelala, ma o ke kaʻina hana hui pū ʻia o ka hoʻokaʻawale ʻana o ka magnetic nāwaliwali + magnetic ikaika + umekaumaha, ua koho ʻia nā concentrates ilmenite me ka hua o 25.37%, kahi papa TiO2 o 46.39%, a me ka helu hoʻōla o 60.83%. ʻO ka concentrate rutile me ka hua o 8.52%, ka papa TiO2 o 66.15% a me ka hoʻōla ʻana o 29.15%; ʻO ka Zircon placer concentrate me ka hua o 40.15%, kahi papa ZrO2 o 58.06%, a me ka helu hoʻōla o 89.41%. Loaʻa i ka concentrate hao ka nui o ka titanomagnetite, no laila ʻaʻole hiki ke koho ʻia nā huahana concentrate hao kūpono.
