Bauxite amatanthauza miyala yomwe ingagwiritsidwe ntchito m'makampani, ndipo pamodzi imatchedwa ore yopangidwa ndi gibbsite ndi monohydrate monga mchere waukulu. Bauxite ndiye zida zabwino kwambiri zopangira zitsulo zotayidwa, ndipo kugwiritsa ntchito kwake kumapitilira 90% yazotulutsa zonse padziko lapansi. Minda yogwiritsira ntchito bauxite ndi zitsulo komanso zopanda zitsulo. Ngakhale kuchuluka kwazinthu zopanda zitsulo ndizochepa, zimakhala ndi ntchito zambiri. Bauxite ntchito makampani mankhwala, zitsulo, ziwiya zadothi, zipangizo refractory, abrasives, adsorbents, makampani kuwala, zomangira, makampani asilikali, etc.
Ore katundu ndi mchere kapangidwe
Bauxite ndi osakaniza angapo mchere (hydroxides, dongo mchere, oxides, etc.) ndi aluminium hydroxide monga chigawo chachikulu. Imatchedwanso "bauxite" ndipo nthawi zambiri imaphatikizapo gibbsite. , Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite ndi mchere wina wambiri, zomwe zimapangidwa makamaka ndi AI2O3, SiO2, Fe2O3, TiO2, sekondale Zosakaniza zikuphatikizapo CaO, MgO, K2O, Na2O, S, MnO2 ndi zinthu organic, etc., zoyera, imvi, imvi-chikasu, yellow wobiriwira, wofiira, bulauni, etc.
Kupindula ndi kuyeretsedwa
Mwala wina waiwisi wokumbidwa kuchokera ku bauxite ukhoza kukwaniritsa zofunikira pakugwiritsa ntchito. Bauxite wamba amatsimikizira njira yopezera phindu potengera mtundu wa mchere wodetsedwa. Panthawi imodzimodziyo, zonyansa zomwe zimagwirizanitsidwa ndi mchere wokhala ndi aluminiyumu mu bauxites zina zimakhala zovuta kuchotsa mwamakina kapena mwakuthupi.
01
Magulu a Beneficiation
Mchenga wa granular wa quartz ndi bauxite wa ufa ukhoza kulekanitsidwa ndi kuchapa, sieving kapena njira zopangira kuti zikhale bwino. Ndi yoyenera kwa boehmite yokhala ndi silicon yayikulu.
02
Mphamvu yokoka
Kugwiritsa ntchito heavy medium beneficiation kumatha kulekanitsa dongo lofiira lomwe lili ndi chitsulo mu bauxite, ndipo cholumikizira chozungulira chimatha kuchotsa siderite ndi mchere wina wolemera.
03
Kupatukana kwa maginito
Kugwiritsa ntchito ofooka maginito kulekana akhoza kuchotsa chitsulo maginito mu bauxite, ndi ntchito amphamvu maginito olekanitsa zida monga mbale maginito olekanitsa, ofukula mphete mkulu gradient maginito olekanitsa, electromagnetic slurry maginito olekanitsa akhoza kuchotsa okusayidi chitsulo, titaniyamu ndi chitsulo silicate, etc. Kusankhidwa kwa zipangizo zofooka za maginito kumatha kuonjezera zitsulo zotayidwa pamene kuchepetsa mtengo wa alumina kupanga ndi kukonza.
04
Kuyandama
Kwa sulfides monga pyrite yomwe ili mu bauxite, xanthate flotation ingagwiritsidwe ntchito kuchotsa; kuyandama kwabwino ndi kubweza kungagwiritsidwenso ntchito kuchotsa zonyansa monga pyrite, titaniyamu, silicon, kapena kusankha AI2O3 zomwe zili mpaka 73% Ya bauxite yoyera kwambiri.
