摘要: Abstract The effluents from acid plants generated in copper pyrometallurgy contain high concentrations of sulphates and heavy metals that difficult further reuse contained water. In this study, the neutralization an effluent was studied by progressive addition lime as a pH-modifying agent. Batch continuous tests were conducted to evaluate potential between pH 1 11 on containing As, Cu, Fe, Zn, Ni, Pb, Cd, Hg, Sb, Mn, Mo, Al SO42−. batch process neutralization, efficiency about 99.5% attained except for Sb 98% Pb 97%. Similar values obtained mode. production gypsum with commercial value also evaluated based Chilean standard hazardous solid waste measured TCLP (Toxicity characteristic leaching procedure) test. Best results 2, after minimum four washes. rheology residual solids characterized using filtration sedimentation rate determined different flocculants. final liquid ASTM corrosion test showed non-corrosive nature, 0.07 mm/year, well below allowed established 6.35 mm/year.
