Abstract
1502775 Precipitation of arsenic from acidic effluents BORAX CONSOLIDATED Ltd (BRITISH CO) 30 June 1975 [28 June 1974] 28770/74 Heading C1C A process for the removal of arsenic from acidic aqueous solutions comprises (a) treating with an arsenic precipitant and removing the arsenic precipitated, and (b) treating the aqueous liquor obtained with a ferric iron salt in solution or with a ferrous iron salt and an oxidizing agent, to complete the precipitation of the arsenic. The acidic effluents may be those produced in the gaswashing circuits of sulphuric acid plants which are associated with copper smelters. The precipitant may be lime, and the iron salts may be ferric chloride or ferrous sulphate, and the oxidizing agent may be chlorine, hypochlorite, permanganate or peroxide. Waste liquors containing less than 0À25 p.p.m. of soluble arsenic are obtained.
