Ko te bauxite e pā ana ki te konganuku ka taea te whakamahi i roto i te ahumahi, ā, e kiia ana ko te konganuku i hangaia mai i te gibbsite me te monohydrate hei kohuke matua. Ko te bauxite te rauemi mata pai rawa atu mō te hanga konumohe whakarewa, ā, neke atu i te 90% o te katoa o te putanga bauxite o te ao e whakamahia ana. Ko ngā mara tono o te bauxite he konganuku me te kore-konganuku. Ahakoa he iti te nui o te kore-konganuku, he whānuitia ōna whakamahinga. Ka whakamahia te bauxite i roto i te ahumahi matū, te whakarewa, te uku, ngā rauemi ātete, ngā mea whakakoi, ngā mea mimiti, te ahumahi māmā, ngā rauemi hanga, te ahumahi hōia, me ētahi atu.
Ngā āhuatanga o te kohuke me te hanganga o te kohuke
He ranunga te bauxite o ngā kohuke maha (ngā hauwaiora, ngā kohuke uku, ngā waikura, me ētahi atu) me te hauwaiora konumohe hei wāhanga matua. Ka kiia hoki ko te "bauxite" ā, kei roto i te nuinga o te wā ko te gibbsite. , Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite me te maha atu o ngā kohuke, ko te hanganga matū matua ko te AI2O3, SiO2, Fe2O3, TiO2, tuarua. Kei roto i ngā kai ko te CaO, MgO, K2O, Na2O, S, MnO2 me ngā mea rauropi, me ētahi atu, he mā, he hina, he hina-kōwhai, he kōwhai-kakariki, he whero, he parauri, me ētahi atu.
Te painga me te purenga
Ka taea e ētahi o ngā konganuku mata i keria mai i te bauxite te whakatutuki i ngā whakaritenga o te tono. Mā te bauxite tikanga ka whakatauhia te tukanga painga i runga i te āhua o ngā kohuke poke e pā ana. I taua wā anō, he uaua ki te tango i ngā poke e pā ana ki ngā kohuke kei roto he konumohe i roto i ētahi bauxite mā te miihini, mā te tinana rānei.
01
Whakarōpūtanga painga
Ka taea te wehewehe i te onepū kiripaka me te paura bauxite mā te horoi, te tātari, te whakarōpū rānei hei whakapai ake i te kounga. He pai mō te boehmite he nui te ihirangi silicon.
02
Te painga o te kaha ā-papatipu
Mā te whakamahinga o te whakangawari reo taumaha ka taea te wehe i te uku whero kei roto he rino i roto i te bauxite, ā, ka taea e te pūwhakakotahi porowhita te tango i te siderite me ētahi atu kohuke taumaha.
03
Wehenga aukume
Mā te whakamahinga o te wehenga aukume ngoikore ka taea te tango i te rino aukume i roto i te bauxite, ā, mā te whakamahinga o ngā taputapu wehenga aukume kaha pērā i te wehenga aukume pereti, te wehenga aukume porowhita teitei poutū, te wehenga aukume paru hikohiko ka taea te tango i te waikura rino, te titanium me te silicate rino, me ētahi atu. Mā te whiriwhiri i ngā rauemi aukume ngoikore ka taea te whakanui ake i te ihirangi konumohe me te whakaiti i te utu o te hanga me te tukatuka alumina.
04
Te Whakaterenga
Mō ngā whanariki pērā i te pyrite kei roto i te bauxite, ka taea te whakamahi i te xanthate flotation hei tango; ka taea hoki te whakamahi i te pai me te whakamuri flotation hei tango i ngā poke pērā i te pyrite, te titanium, te silicon, te whiriwhiri rānei i te ihirangi AI2O3 tae atu ki te 73% o te bauxite parakore teitei.
Te whakaputa alumina
Ko te tukanga Bayer te mea nui hei whakaputa alumina mai i te bauxite. He māmā noa iho tēnei tukanga, he iti te whakapaunga pūngao me te utu, ā, he pai te kounga o te hua. ). Mō te bauxite he iti te ōwehenga o te konumohe ki te silicon, ka whakamahia te tikanga sintering houra raima, ā, ka taea hoki te whakamahi i te tikanga Bayer me te tikanga sintering houra raima i roto i te tukanga whakaputa whakakotahi.
Te whakaputanga o te tote konumohe
Mā te whakamahi i te bauxite, ka taea te whakaputa i te konupūmā whanariki mā te tikanga waikawa whanariki, ā, ka taea te whakaputa i te polyaluminum chloride mā te tikanga whakatōpū waikawa hauwai pāmahana-tiketike.
