I-Bauxite ibhekisela kwi-ore enokuthi isetyenziswe kwishishini, kwaye ngokudibeneyo ibizwa ngokuba yi-ore eyenziwe yi-gibbsite kunye ne-monohydrate njengezona zimbiwa eziphambili.I-Bauxite yeyona nto ingcono kakhulu yokuvelisa i-aluminiyam yesinyithi, kwaye ukusetyenziswa kwayo kubalela ngaphezu kwe-90% yemveliso ye-bauxite yehlabathi.Iinkalo zokusetyenziswa kwe-bauxite ziyintsimbi kunye ne-non-metal.Nangona inani le-non-metal lincinci, linoluhlu olubanzi lokusetyenziswa.I-Bauxite isetyenziswa kushishino lweekhemikhali, i-metallurgy, i-ceramics, i-refractory materials, i-abrasives, i-adsorbents, i-industry light, izixhobo zokwakha, imboni yezomkhosi, njl.
Iipropati ze-Ore kunye nesakhiwo sezimbiwa
I-Bauxite ngumxube weeminerali ezininzi (i-hydroxides, iiminerali zodongwe, i-oxides, njl.) kunye ne-aluminium hydroxide njengeyona nto iphambili.Ikwabizwa ngokuba yi "bauxite" kwaye ihlala ibandakanya i-gibbsite., I-Diaspore, i-boehmite, i-hematite, i-kaolin, i-opal, i-quartz, i-feldspar, i-pyrite kunye nezinye iiminerali ezininzi, ukubunjwa kweekhemikhali ikakhulu yi-AI2O3, SiO2, Fe2O3, TiO2, yesibini Izithako ziquka i-CaO, MgO, K2O, Na2O, S, I-MnO2 kunye ne-organic matter, njl., kumhlophe, grey, grey-yellow, yellow-green, obomvu, omdaka, njl.
Ukuxhamla kunye nokuhlanjululwa
Enye intsimbi ekrwada yombiwa kwi-bauxite inokuhlangabezana neemfuno zesicelo.I-bauxite eqhelekileyo imisela inkqubo yokuzuza ngokusekwe kubume beeminerali ezingacocekanga ezinxulumeneyo.Ngelo xesha, ukungcola okuhambelana neeminerali ezine-aluminium kwezinye ii-bauxites kunzima ukususa ngomatshini okanye ngokomzimba.
01
Ukuhlelwa kwenzuzo
Isanti ye-quartz yegranular kunye ne-bauxite engumgubo inokwahlulwa ngokuhlamba, ukuhluza okanye iindlela zokuhlela ukuphucula umgangatho.Ifanelekile kwi-boehmite enomxholo ophezulu we-silicon.
02
Uncedo lomxhuzulane
Ukusetyenziswa kwe-beneficiation enzima ephakathi kunokwahlula udongwe olubomvu olunentsimbi kwi-bauxite, kwaye i-spiral concentrator inokususa i-siderite kunye nezinye iiminerali ezinzima.
03
Ukwahlukana kwemagneti
Ukusetyenziswa kokwahlukana kwemagnethi ebuthathaka kunokususa i-iron magnetic kwi-bauxite, kunye nokusetyenziswa kwezixhobo eziqinileyo zokwahlula imagnethi ezifana nepleyiti yokwahlula imagnethi, umsesane othe nkqo ophakamileyo we-gradient separator magnetic, i-electromagnetic slurry separator magnetic inokususa i-iron oxide, i-titanium kunye nentsimbi ye-silicate, njl. Ukukhethwa kwezinto ezibuthathaka zamagnetic kunokunyusa umxholo we-aluminium ngelixa unciphisa iindleko zemveliso ye-alumina kunye nokucubungula.
04
Ukuphaphatheka
Kwii-sulfides ezifana ne-pyrite equlethwe kwi-bauxite, i-xanthate flotation ingasetyenziselwa ukususa;Ukujikeleza okuhle kunye nokubuyela umva kungasetyenziselwa ukususa ukungcola okufana ne-pyrite, i-titanium, i-silicon, okanye ukhethe umxholo we-AI2O3 ukuya kwi-73% ye-bauxite ephezulu.
Ukuvelisa i-alumina
Inkqubo ye-Bayer isetyenziselwa ukuvelisa i-alumina kwi-bauxite.Le nkqubo ilula, ukusetyenziswa kwamandla kunye neendleko ziphantsi, kwaye umgangatho wemveliso ulungile.).Kwi-bauxite enomlinganiselo ophantsi we-aluminiyam ukuya kwi-silicon, indlela ye-soda lime ye-sintering yamkelwa, kunye nendlela ye-Bayer kunye ne-soda lime sintering method ingasetyenziswa kwinkqubo yokuvelisa edibeneyo.
Ukuveliswa kwetyuwa ye-aluminium
Nge-bauxite, i-aluminium sulfate inokuveliswa ngendlela ye-sulfuric acid, kunye ne-polyaluminium chloride inokuveliswa nge-high-temperature ye-hydrochloric acid precipitation method.
