摘要
通过用Ｈ２Ｏ２对某金矿金精矿进行助金的氰化浸出试验研究，探讨了在实际浸出过程中矿浆ＰＨ值对Ｈ２Ｏ２稳定性的影响，Ｈ２Ｏ２用量对矿浆放氧速度、溶氧量和金的浸出率的影响．结果表明，过氧化氢助金浸出可大大缩短金的浸出时间，提高浸出率．
ased on the H2O2-assisting cyanide leaching tests on the gold concentrate of a certain mine, the paper discusses the effect of the PH value of pulp on the H2O2 stability and the effect of H2O2 amount on the oxygen release velocity of the pulp, oxygen dissolution amount and gold leaching rate during the practical leaching process. The results have shown that H2O2-assisting cyanide leaching can greatly shorten the gold leaching time and raise leaching rate.
