Abstract: Concentrated sulfide ore containing zinc(ZnS) from Youxi,Fujian Province,China was used to prepare ZnSO_4.The ZnS ore was soaked with H_2SO_4,Fe(Ⅲ) salt(s) as a catalyst.The leaching yield of Zn in the ore was up to 85%,when the molar ratio of ZnS ore,Fe(Ⅲ) salt(s) ,H_2SO_4 is 1∶2∶0.8,the ore powder size is not larger than 140 mesh, the mixture of ore powder ,Fe(Ⅲ) salt(s) and H_2SO_4 was stirred at 90 ℃ for 5 h. The product (ZnSO_4·7H_2O) quality was up to 98%.
