Na Waiwai Ore a me ke Kino Minerale
Aia ma kahi o 120 mau ʻano minerala i loko o ka phosphorus i ʻike ʻia ma ke ʻano, akā no ka mea, ʻo nā minerala ʻoihana i loaʻa i ka phosphorus ka nui o nā minerala phosphate ma apatite a me ka pōhaku phosphate. ʻO apatite [Ca5(PO4)3(OH,F)] he mineral nona ka mea nui he calcium phosphate. Loaʻa nā inoa like ʻole ma muli o nā mea like ʻole i loko, e like me ka fluorine a me ka chlorine. ʻO nā minerala phosphorus maʻamau: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, a me nā mea'ē aʻe. ʻO ka manaʻo o ka P2O5 ma waena o 40.91 a me 42.41%. Hiki i nā anion hou F, OH, CO3, a me O i loko o ka pōhaku phosphate ke hoʻololi i kekahi i kekahi, a he nui nā mea isomorphic, no laila ke hoʻololi nui ʻia ke ʻano kemika o ka mineral.
ʻO ka hui kemika maʻamau o ka apatite

Hiki ke hoʻokaʻawale ʻia ka pōhaku Phosphate i ke ʻano siliceous, ʻano calcareous, a me ke ʻano silicon (calcium)-calcium (silicon). ʻO nā mineral e pili ana he quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, rare earth. , magnetite, ilmenite, limonite, etc., flotation method is the most important beneficiation method for apatite.
ʻO ke kaʻina hana ʻenehana nui ka: flotation + magnetic separation combined process, grinding + classification + flotation process, stage grinding + stage separation process, roasting + digestion + classification process.

Ka Hana ʻana i nā Pūnaehana Phosphate o nā mea hoʻomeamea Phosphate
ʻO ka hana ʻana i ka mea hoʻomomona Phosphate ka hoʻololi ʻana i nā minerala phosphate i phosphates i maʻalahi i nā mea kanu ma o ke kaʻina o ka pōmaikaʻi, kiʻekiʻe wela, a me ka synthesis. ʻO ka Ammonium phosphate kahi mea hoʻohuihui hoʻohuihui kiʻekiʻe i hana ʻia mai ka waikawa phosphoric i loko o ka wai amonia. Loaʻa ka phosphorus melemele ma ka hoʻomehana ʻana i ka pōhaku phosphate i hui pū ʻia me ke one quartz a me ka coke ma 1500 ° C i loko o kahi umu uila. ʻElua mau ala hana o ka phosphoric acid: sulfuric acid extraction method and peroxy combustion absorption method.

ʻO ka maikaʻi o nā huelo hao ma Hebei he -200 mesh, he 63.29%, ʻo ka nui o ka hao TFe he 6.95%, a he 6.89% ka P2O5. ʻO ka hao ka nui o ka iron oxide e like me ka limonite, ka hao silicate a me ka magnetite ma ke ʻano o nā inclusions mau; ʻO nā minerala phosphorus ka nui o ka apatite, nā mineral gangue he quartz, feldspar, calcite, a me nā mea ʻē aʻe. Ua hui pū ʻia me nā mineral phosphorus. ʻO ke kumu o ka hoʻāʻo ʻana, ʻo ia ke koho ʻana i nā minerala hao like ʻole ma ka hoʻokaʻawale magnetic, a ua hoʻonui ʻia ka apatite i nā huelo hoʻokaʻawale magnetic.
E like me nā waiwai o nā laʻana, ua hoʻoholo ʻia ke kaʻina hana o ka pōmaikaʻi penei: ʻo ka ʻaila maka i koho ʻia - 200 mesh me ka fineness o 63.29%, ua hana ʻia i loko o ka slurry me ka hoʻopaʻa ʻana o 30%, a koho ʻia ka hao magnetic mau. e ka CTB4000GS nāwaliwali mākēneki mahina, a ua koho ʻia nā huelo e ke apo kū pololei 0.5T nāwaliwali Magnetic iron oxide a me nā mineral silicate hao.

ʻO nā huelo hao phosphorus i loko o ka hao ua loaʻa i ke kaʻina hana hoʻoneʻe hao o hoʻokahi kaʻa ʻana a hoʻokahi hoʻokahi ʻelua ʻelua, a ʻaʻole hiki ke koho ʻia nā huahana koʻikoʻi o ka hao mai ka mea magnetic. Ua hoʻonui ʻia ka nui o ka phosphorus i loko o ka phosphorus coarse concentrate mai 6.89% a i 10.12%, a ʻo 79.54%. %, ʻo 75.83% ka nui o ka lawe ʻana i ka hao. Ma ka ho'āʻo hoʻohālikelike o nā ikaika kahua like ʻole o Lihuan 0.4T, 0.6T a me 0.8T, ua ʻike ʻia ka ikaika haʻahaʻa o Lihuan 0.4T i hopena i ka hao nui i ka phosphorus coarse a me ka hoʻomaʻemaʻe, a me ka ikaika kahua kiʻekiʻe o 0.8 Ua lilo ka phosphorus i nā mea magnetic.
