Imfucumfucu ebomvu iyizinhlayiya ezinhle kakhulu eziqinile ze-alkaline imfucuza ekhiqizwa kwinqubo yokukhiqiza i-alumina nge-bauxite njengento eluhlaza. Kuwo wonke amathani we-alumina akhiqizwa, acishe abe ngu-0,8 kuya ku-1.5 amathani odaka obomvu akhiqizwa. Ukulondolozwa okukhulu kodaka obomvu akukugcini kuphela izinsiza zomhlaba nezinsizakusebenza, kepha futhi kubangela ukungcoliswa kwemvelo kanye nezingozi zokuphepha.Titanium dioxideI-Waste Liquid yi-hydrolysis wature ketshezi ekhiqizwa lapho iTitanium Dioxide ikhiqizwa yi-sulfuric acid indlela. Kuwo wonke amathani we-titonium dioxide akhiqizwa, akhiqizwa amathani ayi-8 kuye kwayi-10 e-acid engcolile nge-20% kuya ku-80 m3 yamanzi angcolile acidic nge-2% akhiqizwa. Inenani elikhulu lezakhi ezibalulekile ezifana ne-titanium, i-aluminium, iron, i-scandium, ne-sulfuric acid. Ukulahla okuqondile akugcini ngokungcolisa imvelo kuphela, kodwa futhi kubangela ukulahleka okukhulu kwezomnotho.
Udaka olubomvu luyimfucumfucu eqinile ye-alkali ye-alkali, ne-titanium dioxide yokungcola uketshezi olunama-acidic. Ngemuva kokunciphisa i-acid ne-alkali yalezi ezimbili, izinto ezibalulekile zivuselelwa kabusha futhi zisetshenziswa, ezingakwazi kuphela ukugcina ibanga lezindleko zokukhiqiza, kodwa futhi zithuthukise ibanga lezinqubo ezibalulekile ezintweni zokwakha imfucuza noma imfucuza yemfucuza, futhi zilungele kakhulu inqubo elandelayo yokululama. Ukuvuselelwa kabusha okuphelele nokuphinda kusetshenziswe kabusha kwalezi zimboni zezimboni zinokubaluleka okuthile kwezimboni, kanyeScandium oxideInenani eliphakeme nezinzuzo ezinhle zomnotho.
Iphrojekthi yeScandium oxide yokukhishwa kusuka ku-Red Mud kanye ne-Titanium Dioxide yokungcola uketshezi kubaluleke kakhulu ekuxazululeni ukungcoliswa kwemvelo nokuphepha okubangelwa ukugcinwa kwemfucuza ebomvu kanye ne-titanium dioxide yokukhipha uketshezi. Kubuye kube yimboni ebalulekile yokusebenzisa umqondo wokuthuthukisa isayensi, eshintsha imodi yokuthuthukiswa komnotho, ukuthuthukisa umnotho oyindilinga, nokwakha umphakathi osindisa izinsiza kanye nemvelo, futhi unezinzuzo ezinhle zenhlalo.
