Extraction of Zinc from Zinc Sublimber with Sulfuric, Thermal and Extraction Phosphoric Acid

Abstract The study was conducted to extract zinc and the results on extraction of Zn from sublime with solution sulfuric, thermal phosphoric acids are presented depending Solid: Liquid (S:L), concentration duration leaching process. Sulfuric acid used a content 8% which is waste product non-ferrous metallurgy, phosphorites Central Kyzylkum. It has been established that maximum degree noted when using acid, 96-98%, S:L=1:(10-15), temperature 90°C washing sulfuric 99.8% at S:L=1:10 above room temperature. Increasing process over 30 minutes virtually no effect percentage zinc.
