COMPARATIVE STUDY USING LOW COST ACETIC AND SULFURIC ACIDS ON ROASTING AND PEROXIDE FOR LEACHING PROCESS TO EXTRACT PB FROM GALENA

This article aims to present the application of acetic acid and sulfuric for lead (Pb) extraction from galena concentrate applying roasting (600oC 60 min.) peroxide oxidant (0.5 M) min. leaching process. Nowadays, has been broadly applied batteries, besides PVC tubes, chemicals, paint color, alloys joint. The increases percentage Pb extraction. study shows effect concentrations (1.0 M, 1.5 2.0 M), temperatures (30, 50, 70oC), stirring speed (200, 400, 600 rpm) on galena. A particle size ≤ 200 mesh after used AAS determine concentration in solution that is a better agent rather than due sulfate precipitation. Optimization result with achieved 35.64 ppm using M acid, 50oC, rpm. beneficiation low cost acids as potential technique will be developed industrial purpose its economic reason, simplicity, fast
