摘要
混汞尾矿直接用于制粒堆浸 ,金浸出率很低 ,只有 54.7% ,经化学预处理后 ,其载体矿物晶体构造被破坏 ,细散金从矿物中暴露出来 ,金的浸出率有了很大的提高 ,可达 83 .8%。
With the technique of amalgamating ore tailing pelletized to heap leaching,there arrives a low leaching efficiency of no more than 54.7%.Howerer,Amalgamating ore tailing is first treated chemically,the crystal stucture of carrier ore is danaged,and the fing scattered gold becones exposed,so the leaching efficiency can reach up to 83.8%.
