I-Bauxite ibhekisela ku-ore engasetshenziswa embonini, futhi ibizwa ngokuthi i-ore eyakhiwe yi-gibbsite kanye ne-monohydrate njengamaminerali ayinhloko. I-Bauxite iyinto eluhlaza engcono kakhulu yokukhiqizwa kwe-aluminium yensimbi, futhi ukusetshenziswa kwayo kubiza ngaphezu kwama-90% womkhiqizo we-bauxite ophelele emhlabeni. Izinkambu zokusetshenziswa ze-bauxite ziyinsimbi kanye ne-non-metal. Nakuba inani le-non-metal lincane, linokusetshenziswa okubanzi. I-Bauxite isetshenziswa embonini yamakhemikhali, i-metallurgy, i-ceramics, izinto eziphikisayo, i-abrasives, i-adsorbents, imboni elula, izinto zokwakha, imboni yezempi, njll.
Izakhiwo ze-ore kanye nesakhiwo samaminerali
I-Bauxite iyinhlanganisela yamaminerali amaningi (ama-hydroxide, amaminerali obumba, ama-oxide, njll.) ene-aluminium hydroxide njengengxenye eyinhloko. Ibizwa nangokuthi “i-bauxite” futhi imvamisa ifaka i-gibbsite. , I-Diaspore, i-boehmite, i-hematite, i-kaolin, i-opal, i-quartz, i-feldspar, i-pyrite namanye amaminerali amaningi, ukwakheka kwamakhemikhali okuyinhloko yi-AI2O3, i-SiO2, i-Fe2O3, i-TiO2, okwesibili. Izithako zifaka i-CaO, i-MgO, i-K2O, i-Na2O, i-S, i-MnO2 kanye nezinto eziphilayo, njll., ngombala omhlophe, ompunga, ompunga-ophuzi, ophuzi-oluhlaza, obomvu, onsundu, njll.
Ukuzuza kanye nokuhlanzwa
Amanye amatshe aluhlaza ambiwe nge-bauxite angahlangabezana nezidingo zokusetshenziswa. I-bauxite evamile inquma inqubo yokuzuza ngokusekelwe kuhlobo lwamaminerali angcolile ahlobene nawo. Ngesikhathi esifanayo, ukungcola okuhlobene namaminerali aqukethe i-aluminium kwamanye ama-bauxite kunzima ukukususa ngomshini noma ngokomzimba.
01
Ukuhlukaniswa kwezinzuzo
Isihlabathi se-quartz esine-granular kanye ne-bauxite ewuphuphu kungahlukaniswa ngezindlela zokuwasha, zokusihla noma zokuhlukanisa ukuze kuthuthukiswe ikhwalithi. Ifanele i-boehmite enokuqukethwe okuphezulu kwe-silicon.
02
Ukuzuza amandla adonsela phansi
Ukusetshenziswa kokwenza i-heavy medium beneficiation kungahlukanisa ubumba olubomvu oluqukethe insimbi ku-bauxite, futhi i-spiral concentrator ingasusa i-siderite namanye amaminerali asindayo.
03
Ukuhlukaniswa kwamagnetic
Ukusetshenziswa kokuhlukaniswa okubuthakathaka kwamandla kazibuthe kungasusa insimbi kazibuthe ku-bauxite, kanye nokusetshenziswa kwemishini eqinile yokuhlukaniswa kwamandla kazibuthe njenge-plate magnetic separator, i-vertical ring high gradient magnetic separator, i-electromagnetic slurry magnetic separator kungasusa i-iron oxide, i-titanium kanye ne-iron silicate, njll. Ukukhethwa kwezinto ezibuthakathaka kwamandla kazibuthe kungandisa okuqukethwe kwe-aluminium ngenkathi kunciphisa izindleko zokukhiqizwa nokucubungula kwe-alumina.
04
Ukuntanta
Kuma-sulfide afana ne-pyrite equkethwe ku-bauxite, i-xanthate flotation ingasetshenziswa ukususa; i-positive kanye ne-reverse flotation ingasetshenziswa futhi ukususa ukungcola okufana ne-pyrite, i-titanium, i-silicon, noma ukukhetha okuqukethwe kwe-AI2O3 kuze kufike ku-73% we-bauxite emsulwa kakhulu.
Ukukhiqiza i-alumina
Inqubo yeBayer isetshenziswa kakhulu ukukhiqiza i-alumina nge-bauxite. Le nqubo ilula, ukusetshenziswa kwamandla kanye nezindleko kuphansi, futhi ikhwalithi yomkhiqizo ilungile. ). Ku-bauxite enesilinganiso esiphansi se-aluminium ne-silicon, kusetshenziswa indlela yokusinta i-soda lime, kanti indlela yeBayer kanye nendlela yokusinta i-soda lime nazo zingasetshenziswa enqubweni yokukhiqiza ehlanganisiwe.
Ukukhiqizwa kukasawoti we-aluminium
Nge-bauxite, i-aluminium sulfate ingakhiqizwa ngendlela ye-sulfuric acid, kanti i-polyaluminum chloride ingakhiqizwa ngendlela ye-hydrochloric acid precipitation enezinga lokushisa eliphezulu.
