I-Bauxite ibhekisela ku-ore engasetshenziswa embonini, futhi ngokuhlanganyela ibizwa ngokuthi i-ore eyakhiwe i-gibbsite ne-monohydrate njengamaminerali ayinhloko.I-Bauxite iyimpahla yokusetshenziswa engcono kakhulu yokukhiqiza i-aluminiyamu yensimbi, futhi ukusetshenziswa kwayo kubala ngaphezu kuka-90% wesamba somkhiqizo we-bauxite womhlaba.Izinkambu zokusetshenziswa kwe-bauxite ziyinsimbi futhi zingezona ezensimbi.Nakuba inani le-non-metal lincane, linokusetshenziswa okubanzi.I-Bauxite isetshenziswa embonini yamakhemikhali, i-metallurgy, i-ceramics, izinto eziphikisayo, ama-abrasives, ama-adsorbents, imboni yokukhanya, izinto zokwakha, imboni yezempi, njll.
Izakhiwo ze-Ore kanye nesakhiwo samaminerali
I-Bauxite iyingxube yamaminerali amaningi (ama-hydroxides, amaminerali obumba, ama-oxides, njll.) ne-aluminium hydroxide njengengxenye eyinhloko.Ibizwa nangokuthi "i-bauxite" futhi ngokuvamile ihlanganisa i-gibbsite., I-Diaspore, i-boehmite, i-hematite, i-kaolin, i-opal, i-quartz, i-feldspar, i-pyrite namanye amaminerali amaningi, ukwakheka kwamakhemikhali okuyi-AI2O3, SiO2, Fe2O3, TiO2, yesibili Izithako zifaka i-CaO, MgO, K2O, Na2O, S, I-MnO2 nezinto eziphilayo, njll., ngombala omhlophe, ompunga, ompunga-ophuzi, ophuzi-oluhlaza okotshani, obomvu, onsundu, njll.
Ukuhlomula nokuhlanzwa
Enye insimbi eluhlaza embiwa ku-bauxite ingahlangabezana nezidingo zohlelo lokusebenza.I-bauxite evamile inquma inqubo yokuzuza ngokusekelwe kumvelo yamaminerali ahlobene nokungcola.Ngesikhathi esifanayo, ukungcola okuhlobene namaminerali aqukethe i-aluminium kwamanye ama-bauxite kunzima ukukususa ngomshini noma ngokomzimba.
01
Ukuhlukaniswa kwenzuzo
Isihlabathi sequartz esiyimbudumbudu kanye ne-bauxite eyimpuphu zingahlukaniswa ngokuwasha, ukusefa noma izindlela zokugreda ukuze kuthuthukiswe ikhwalithi.Ifanele i-boehmite enokuqukethwe okuphezulu kwe-silicon.
02
Ukuzuza amandla adonsela phansi
Ukusetshenziswa kwe-heavy medium beneficiation kungahlukanisa ubumba olubomvu oluqukethe insimbi ku-bauxite, futhi i-concentrator ye-spiral ingasusa i-siderite namanye amaminerali asindayo.
03
Ukuhlukaniswa kwamagnetic
Ukusetshenziswa kokuhlukana okubuthakathaka kazibuthe kungasusa insimbi kazibuthe ku-bauxite, futhi ukusetshenziswa kwemishini yokuhlukanisa kazibuthe eqinile njengepuleti isihlukanisi kazibuthe, indandatho eqondile yesihlukanisi se-gradient magnetic, isihlukanisi se-electromagnetic slurry magnetic singasusa i-iron oxide, i-titanium nensimbi silicate, njll. Ukukhethwa kwezinto ezinozibuthe ezibuthakathaka kungakhuphula okuqukethwe kwe-aluminium ngenkathi kunciphisa izindleko zokukhiqiza nokucubungula kwe-alumina.
04
Ukuntanta
Kuma-sulfide afana ne-pyrite equkethwe ku-bauxite, i-xanthate flotation ingasetshenziswa ukususa;ukuntanta okuhle nokuhlehlayo nakho kungasetshenziswa ukususa ukungcola okufana ne-pyrite, i-titanium, i-silicon, noma ukhethe okuqukethwe kwe-AI2O3 kufika ku-73% we-bauxite ehlanzekile kakhulu.
Ukukhiqiza i-alumina
Inqubo ye-Bayer isetshenziswa kakhulu ukukhiqiza i-alumina kusuka ku-bauxite.Le nqubo ilula, ukusetshenziswa kwamandla nezindleko ziphansi, futhi izinga lomkhiqizo lihle.).Ku-bauxite enesilinganiso esiphansi se-aluminium ne-silicon, indlela ye-soda lime sintering iyamukelwa, futhi indlela ye-Bayer kanye nendlela ye-soda lime sintering ingasetshenziswa enqubweni yokukhiqiza ehlangene.
Ukukhiqizwa kosawoti we-aluminium
Nge-bauxite, i-aluminium sulfate ingakhiqizwa ngendlela ye-sulfuric acid, futhi i-polyaluminium chloride ingakhiqizwa ngendlela yokushisa ephezulu ye-hydrochloric acid.
I-Technical Service Scope ye-Huate Beneficiation Engineering Design Institute
①Ukuhlaziywa kwezinto ezijwayelekile nokutholwa kwezinto ezisansimbi.
②Ukususwa kokungcola nokuhlanzwa kwamaminerali angewona awensimbi, njengesiNgisi, isiShayina, ukuslayida, i-fluorescent, i-Gaoling, i-aluminium ore, i-wax yeqabunga, ikristalu esindayo namanye amaminerali angewona awensimbi.
③Ukuzuza kwensimbi, i-titanium, i-manganese, i-chromium, i-vanadium namanye amaminerali angewona ayoni.
④Ukuzuza kwamaminerali abuthakathaka kazibuthe njenge-tungsten ore, i-tantalum niobium ore, i-durian, ugesi, nefu.
⑤ Ukusetshenziswa okuphelele kwezisetshenziswa zesibili ezifana nezinsila ezihlukahlukene kanye ne-smelting slag.
⑥Ukuzuza okuhlanganisiwe kwamaminerali anombala, kazibuthe, esindayo, nokuntanta.
⑦ Ukuhlunga inzwa ehlakaniphile yamaminerali angewona awensimbi nangewona awensimbi.
⑧ Ukuhlolwa kokuphinda kukhethwe ngokwengxenye yezimboni.
⑨ Ukwengezwa kwempushana ecwebe kakhulu njengokuchotshozwa kwezinto, ukugaywa kwebhola nokugreda.
