　　The pressure-leaching slag from arsenic filter-cake by pressure acid-leaching contains high concentration of sulfur, Bi and Sb.The separation and enrichment of these valuable elements in pressure-leaching slag were studied by the methods of re-desulphurization, chloride-leaching, two-step hydrolysis.Effects of reaction time,temperature, liquid-solid ratio on these processes were researched.
