I-Bauxite ibhekisa kwi-ore engasetyenziswa kushishino, kwaye ibizwa ngokuba yi-ore eyenziwe yi-gibbsite kunye ne-monohydrate njengeeminerali eziphambili. I-Bauxite yeyona nto ilungileyo yokwenza i-aluminium yesinyithi, kwaye ukusetyenziswa kwayo kungaphezulu kwe-90% yemveliso iyonke ye-bauxite yehlabathi. Iindawo zokusetyenziswa ze-bauxite zisinyithi kunye ne-non-metal. Nangona isixa se-non-metal sincinci, sinoluhlu olubanzi lokusetyenziswa. I-Bauxite isetyenziswa kushishino lweekhemikhali, i-metallurgy, i-ceramics, izinto ezichasene ne-refractory, i-abrasives, i-adsorbents, imboni yokukhanya, izixhobo zokwakha, imboni yemikhosi, njl.
Iipropati ze-ore kunye nolwakhiwo lwezimbiwa
I-Bauxite ngumxube weeminerali ezininzi (ii-hydroxide, iiminerali zodongwe, ii-oxides, njl.njl.) kunye ne-aluminium hydroxide njengeyona nto iphambili. Ikwabizwa ngokuba yi-"bauxite" kwaye idla ngokuquka i-gibbsite. , I-Diaspore, i-boehmite, i-hematite, i-kaolin, i-opal, i-quartz, i-feldspar, i-pyrite kunye nezinye iiminerali ezininzi, ukwakheka kweekhemikhali ikakhulu yi-AI2O3, i-SiO2, i-Fe2O3, i-TiO2, yesibini. Izithako ziquka i-CaO, i-MgO, i-K2O, i-Na2O, i-S, i-MnO2 kunye nezinto eziphilayo, njl.njl., ngombala omhlophe, ongwevu, ongwevu-mthubi, otyheli-luhlaza, obomvu, omdaka, njl.njl.
Ukuzuza kunye nokuhlanjululwa
Ezinye i-ore eluhlaza eziveliswe kwi-bauxite zinokuhlangabezana neemfuno zokusetyenziswa. I-bauxite eqhelekileyo imisela inkqubo yokuphucula ngokusekelwe kuhlobo lweeminerali zokungcola ezinxulumene nazo. Kwangaxeshanye, ukungcola okunxulumene neeminerali ezine-aluminium kwezinye ii-bauxite kunzima ukukususa ngoomatshini okanye ngokwasemzimbeni.
01
Uhlu lwezibonelelo
Isanti ye-quartz enemibala kunye ne-bauxite ecoliweyo inokwahlulwa ngeendlela zokuyihlamba, ukuyihluza okanye ukuyilungisa ukuze kuphuculwe umgangatho. Ifanelekile kwi-boehmite enomxholo ophezulu we-silicon.
02
Ukuphucula amandla omxhuzulane
Ukusetyenziswa kwe-heavy medium beneficiation kunokwahlula udongwe olubomvu olune-iron kwi-bauxite, kwaye i-spiral concentrator inokususa i-siderite kunye nezinye iiminerali ezinzima.
03
Ukwahlulwa kwemagnethi
Ukusetyenziswa kokwahlulwa kwemagnethi ebuthathaka kunokususa isinyithi semagnethi kwi-bauxite, kwaye ukusetyenziswa kwezixhobo zokwahlulwa kwemagnethi ezinamandla ezifana ne-plate magnetic separator, i-vertical ring high gradient magnetic separator, i-electromagnetic slurry magnetic separator inokususa i-iron oxide, i-titanium kunye ne-iron silicate, njl. Ukukhethwa kwezinto zemagnethi ezibuthathaka kunokunyusa umxholo we-aluminium ngelixa kunciphisa iindleko zokuveliswa kunye nokucutshungulwa kwe-alumina.
04
Ukudada
Kwi-sulfides ezifana ne-pyrite ekwi-bauxite, i-xanthate flotation ingasetyenziselwa ukususa; i-positive kunye ne-reverse flotation ingasetyenziselwa ukususa ukungcola okufana ne-pyrite, i-titanium, i-silicon, okanye ukhethe umxholo we-AI2O3 ukuya kuthi ga kwi-73% ye-bauxite ecocekileyo kakhulu.
Ukuvelisa i-alumina
Inkqubo yeBayer isetyenziswa kakhulu ukuvelisa i-alumina kwi-bauxite. Le nkqubo ilula, ukusetyenziswa kwamandla kunye neendleko ziphantsi, kwaye umgangatho wemveliso ulungile. ). Kwi-bauxite enomlinganiselo ophantsi we-aluminium kwi-silicon, kusetyenziswa indlela yokusila i-soda lime, kwaye indlela yeBayer kunye nendlela yokusila i-soda lime nazo zingasetyenziswa kwinkqubo yemveliso edibeneyo.
Ukuveliswa kwetyuwa yealuminiyam
Nge-bauxite, i-aluminium sulfate inokuveliswa ngendlela ye-sulfuric acid, kwaye i-polyaluminum chloride inokuveliswa ngendlela ye-hydrochloric acid precipitation yobushushu obuphezulu.
