Aluminium ke atileng ka ho fetisisa tšepe elements fumanoa Lefatšeng. Leha ho le joalo, e aluminium re sebelisa kajeno tabeng ea ka sebōpeho sa tšepe aluminium le ea alumina, tsejoang hape e le oxide e aluminium, e hlahisitseng tloha bauxite. E le hore a lokolle ea alumina tala, bauxite ba tla ea ho ka seo e tsejoang e le tshebetso Bayer, moo bauxite e sithabetseng, ebe halefile ka sejana se pressurized le qhibiliha ka hydroxide sodium (caustic soda). ea alumina e ka nako eo a arohile ho metsoako e meng le litšila tse bauxite e le hore e ka qetella o hloekisitsoeng ka aluminium.
Ka bomalimabe, e litšila siile thoeng khubelu seretse-e nang le chefo le lokela ho lula a tšoere matamo ho fihlela e ka tsitsisa. impoundments tsena li atisa ho matlafatsoa le tsamaisang baeti letsopa kapa a maiketsetso hore boloka thepa caustic ho tloha seeping ka potolohileng mobu kapa fatše metsi. Leha ho le joalo, ho 'nile ha' maloa a Maemong ha matamo oa khubelu seretse ba phunyeletsoe confinements bona 'me ea baka koluoa litaba tsa tikoloho.
ST Helmets & Technology na le tsela e molemo ho hlahisa ea alumina. Tsela STET tlosa silicates arabelang le oxides inert (Fe, Ti) ho tloha bauxite ntle le ho sebelisa thepa e caustic kapa dithulaganyo metsi karohano. Ka triboelectrostatic ea rona e ikhethang mokhoa o omileng oa ho arohana, ka tsela e itseng e khōloanyane ea ea alumina ka ntšitsoeng bauxite ka pele ka Process Bayer. Likarolo setseng ho tloha tshebetso ka sebelisoa tlhahiso ceramic, hammoho le samente ho etsa thepa Portland. The phofo e thumisehileng bōpiloe ke tshebetso ka khona ka metsi ho thibela e tsoa ho e ho bōpa le lerole le maru, empa sephetho le "seretse" ha e na le thepa ea caustic le ke ka ho phethahetseng sireletsehileng bakeng sa tikoloho.
kahoo, haeba u eketsa ho fihlela melemo eohle, ST Helmets & mokhoa Technology e ke ho ka ba molemo mefuta e meng. Ho boloka ka ditjeo tsa ho sebelisa mehaho ke theola tshebediso ya soda caustic, e leng bobeli le tla rua molemo ha theko hammoho le e le tlhohonolofatso eo tikoloho. E boetse e pholosa chelete ka ho etsa pele ho-Bayer sebetsa bauxite ho, sephetho le ka tlaase ho moo eneji, le hlokahalang bakeng sa ho futhumatsa le pressurize poso-arohane thepa. le, le ST Helmets & Technology thulaganyou e ke eneji, le sebetsang hantle, kahoo, ho ka potlako sebetsa ka bophahamo ba modumo phahameng ea thepa ho boloka tshebetso meepo ho fallela pele.
