高砷含铋净化渣处理工艺研究摘 要:研究“碱浸脱砷—酸浸除铜—中和沉铜”回收高砷含铋净化渣中铋、铜的处理工艺.碱浸脱砷控制终点游离碱度40-50g/L,砷浸出率达到86.3%、氯浸出率达到96.4%;酸浸除铜控制酸度100 g/L,铜浸出率达到90.9%,酸浸渣中铋含量高达40%,可作为优质原料进入铋反射炉冶炼生产4N精铋;中和沉铜pH值7-8,沉铜渣含铜高达52.12%,可作为生产硫酸铜等化工产品的原料.关键词:铋;净化渣;碱浸;酸浸;中和
High arsenic bismuth containing sludge treatment technology research Abstract: Research "alkaline leaching arsenic acid leaching copper and copper deposition" recovery of high arsenic bismuth containing purified dregs of bismuth, copper processing technology. Alkaline leaching arsenic removal control end free alkalinity 40-50g/L, arsenic leaching rate reached 86.3%, chlorine leaching rate reached 96.4%; acid leaching of copper to control the acidity of 100 g/L, the leaching rate of copper reached 90.9%, acid leaching of bismuth content in slag is up to 40%, can be used as high-quality raw materials into the smelting bismuth reverberatory furnace production 4N refined bismuth and copper deposition; pH 7-8, Shen copper slag of copper containing up to 52.12%, can be used to produce copper sulfate and other chemical products raw materials. Keywords: bismuth; purifying slag; leaching; leaching;
