Okuxhunyanwa sokuqala zethu ezingokwenyama aluminium yokucwenga kuyinto bauxite. Njengoba i-aluminium iyinto esebenzayo futhi ingenzeki ngokwemvelo, ore izidingo aluminium-ocebile ukuba elicwengisiswe ukuba umkhiqizo alumina kanye ne-aluminium, kuholele esizukulwaneni esibalulekile sensali yomkhiqizo.
Ukwehla okukhulu kunqubo yokucolisisa ye-bauxite, inqubo yeBayer, ukudalwa kwezinsalela ze-alumina zokucoca kabusha (Fika)-Iyaziwa nangokuthi “udaka olubomvu” - isifudumezi esinobuthi esidinga ukutholakala emigodini futhi sibhekwe isikhathi eside, ngezindleko eziphakeme. Lokhu kubeka isigaba sezinhlekelele ezingahle zibe yingozi emvelweni nasempilweni yabantu uma amachibi okubamba ehluleka ngenxa yanoma yisiphi isizathu futhi udaka obomvu lungena emithonjeni yamanzi asendaweni noma ezindaweni ezinabantu abaningi. Naphezu kocwaningo oluningi oluqhubekayo, alikho izinga elibalulekile lokuhweba lokusebenzisa kabusha okunenzuzo.
ST Izinsiza kusebenza & ubuchwepheshe LLC (STET) usungule isihlukanisi sebhande le-tribo-electrostatic ibhande elilungele ukuzuzwa kwenhlawulo enkulu (ngaphansana kwe-micron) ukuze ngokulinganisela indawo (500 microns) izinhlayiya zamaminerali. Inqubo yokulinganisa ephezulu yeleveli isebenza kahle futhi inamandla okwandisa i-alumina etholakala ku-bauxite ngenkathi inciphisa i-silika esebenzayo futhi ephelele.
Inqubo ye-STET ingamanzi nhlobo ngamakhemikhali, kuholele umkhiqizo owomile we-bauxite ongasetshenziswa ngokunenzuzo ekwakheni usimende, udaka ngokungafani obomvu. Inqubo ye-STET isusa ezinye izinto ezingcolisayo ebezingenqatshwa yinqubo yeBayer njengodaka obomvu. Nokho, inqubo ye-STET isebenza engxenyeni yezindleko zenqubo yeBayer. Ngaphezu kwalokho, imiphumela ye-bauxite ethuthukisiwe yokonga kwinqubo yeBayer, kufaka phakathi ukusetshenziswa okuphansi kwe-caustic soda, isidingo esinciphile somthombo wamanzi amasha, ukonga amandla ngenxa yevolumu ephansi yama-inert oxides, kanye nokwehliswa kwemikhiqizo yodaka ebomvu. Kwezinye izimo, ukuhlelwa kwesihlukanisi se-STET; -ngenamanzi futhi ayinawo amakhemikhali, i-bauxite ebanga eliphansi, kungathengiswa ngisho nakubakhiqizi besimende ukuthola izindleko zokwenza izinto.
Ngaphezu kwalokho, Ubuchwepheshe be-STET bunganikeza abakhiqizi be-bauxite nabahlaziyi be-alumina ezinye izinzuzo ezingeziwe kufaka phakathi izindleko zokunciphisa izinto ze-bauxite, ukunwetshwa kwempilo yesiza sokulahla udoti, kanye nempilo eyandisiwe yokusebenza kwezimayini ze-bauxite ezikhona ngokuthuthukisa ukusetshenziswa kwe -ryry nokwandisa ukululama. Amanzi- nemikhiqizo engenayo yamakhemikhali ekhiqizwa inqubo ye-STET nayo iyasebenziseka ekwenzeni usimende ngamanani aphezulu ngaphandle kwangaphambi kokulashwa.
Uma uyifaka yonke, "ama-win" amaningi ongawusebenzela imisebenzi yakho ye-alumina. Imininingwane ST Izinsiza kusebenza & ubuchwepheshe and let us help you gain more from your current operations while lowering your operating costs and increasing your environmental friendliness.
