【I-Huate Encyclopedia of Mineral Processing】Ucwaningo kanye nokusetshenziswa kwe-Bauxite Processing Technology

I-Bauxite ibhekisela ku-ore engasetshenziswa embonini, futhi ngokuhlangene ibizwa ngokuthi i-ore eyakhiwe i-gibbsite ne-monohydrate njengamaminerali ayinhloko. I-Bauxite iyimpahla esetshenziswayo 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 se-quartz 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, kanye nokusetshenziswa kwemishini yokuhlukanisa kazibuthe eqinile njengepuleti lesihlukanisi kazibuthe, isihlukanisi esime mpo se-high gradient magnetic, isihlukanisi se-electromagnetic slurry magnetic singasusa i-iron oxide, i-titanium ne-iron silicate, njll. Ukukhethwa kwezinto ezibuthakathaka kazibuthe 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% Ye-bauxite ehlanzekile kakhulu.

Ukukhiqiza i-alumina

Inqubo ye-Bayer isetshenziswa kakhulu ukukhiqiza i-alumina kusuka ku-bauxite. Le nqubo ilula, ukusetshenziswa kwamandla kanye 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.
