摘要
缅甸某砷铜炭质金矿中的金系难浸矿物之一。直接用碳浆工艺氰化浸出金的浸出率为60％。矿物中的铜在氰化过程中易形成Cu（CN）2沉淀覆盖在矿物表面上，阻碍金的进一步氰化反应。研究中在金矿石中添加助浸剂后，矿石中的一些矿物与之反应，使金的氰化速度增加，浸出率达到了90％-92％。
The gold of some burmese charcoal gold ore containing arsenic, cuprum is one of the minerals which is difficult to soak. Straight taking over the use of the carbon thick liquid craft cyaniding leaching, the gold leaching rate is 60%. The copper in the mineral is easy to forms the Cu （CN） 2 precipitations covering on mineral surface during the cyaniding process, which will hindrance the further gold cyaniding response. In our study after adding the help - soak reagent into the gold ore, some minerals have the chemical reaction with it, increasing the gold cyaniding speed, the leaching rate has achieved 90% - 92%.
