摘要
河南中原黄金冶炼厂为了提高含硫金精矿金的回收率及充分利用矿石中的有价元素,先用硫酸浸出焙烧渣,铁的浸出率达到95%以上;浸铁后焙烧渣氰化浸出金,金的浸出率达到98%以上。铁的浸出液用来生产氧化铁红,产品质量达到国家标准。
To increase gold recovery in sulphur-bearing gold concentrates and fully utilize valuable elements in the ores at Zhongyuan Gold Smeltery in Henan Province,the roasting slag was firstly leached with sulphuric acid and the leaching rate of iron reached above 95%.Then gold was leached by cyanidation with roasting slag and the leaching rate of gold reached above 98%.Iron oxide red was produced with iron leaching solution,with product quality up to national standard.
