[Rarraba fasaha] Fitar scandium oxide ta hanyar haɗa jajayen laka tare da sharar acid titanium dioxide

Jan laka wani abu ne mai kyau sosai mai ƙarfi mai ƙarfi mai ƙaƙƙarfan sharar gida wanda aka samar a cikin aiwatar da samar da alumina tare da bauxite azaman ɗanyen abu. Ga kowane tan na alumina da aka samar, ana samar da kusan tan 0.8 zuwa 1.5 na jan laka. Adana manyan laka na jan laka ba kawai yana mamaye ƙasa da ɓarna albarkatu ba, har ma yana haifar da gurɓataccen muhalli da haɗarin aminci cikin sauƙi.Titanium dioxidesharar ruwa shine ruwan sharar ruwa na hydrolysis da aka samar lokacin da aka samar da titanium dioxide ta hanyar sulfuric acid. Ga kowane ton na titanium dioxide da aka samar, ana samar da ton 8 zuwa 10 na sharar acid tare da maida hankali na 20% da 50 zuwa 80 m3 na ruwan datti na acidic tare da maida hankali na 2%. Ya ƙunshi babban adadin abubuwa masu mahimmanci kamar titanium, aluminum, iron, scandium, da sulfuric acid. Fitarwa kai tsaye ba wai kawai yana gurɓata muhalli sosai ba, har ma yana haifar da asarar tattalin arziƙi.

Jan laka shine ƙaƙƙarfan ƙaƙƙarfan sharar alkaline, kuma sharar titanium dioxide ruwa ne mai acidic. Bayan neutralizing da acid da alkali na biyu, da muhimmanci abubuwa da ake comprehensively sake yin fa'ida da kuma amfani, wanda ba zai iya kawai ajiye samar da halin kaka, amma kuma inganta sa na muhimmanci abubuwa a cikin sharar gida kayan ko sharar gida ruwa, kuma shi ne mafi m ga na gaba dawo da. tsari. Cikakken sake amfani da sharar masana'antu biyu yana da takamaiman mahimmancin masana'antu, da kumascandium oxideyana da ƙima mai girma da fa'idodin tattalin arziki mai kyau.
Aikin hakar oxide na scandium oxide daga jan laka da ruwan sharar titanium dioxide yana da matukar ma'ana ga magance gurbacewar muhalli da hatsarori da ke haifar da jajayen laka da fitar da sharar titanium dioxide. Har ila yau, wani muhimmin tsari ne na aiwatar da manufar ci gaban kimiyya, da sauya yanayin bunkasuwar tattalin arziki, da raya tattalin arziki madauwari, da gina al'umma mai ceton albarkatu da kyautata muhalli, kuma yana da kyakkyawar fa'ida ta zamantakewa.
