摘要
对难浸半氧化金矿石进行氰化浸出时 ,加入助浸剂过氧化钙可明显提高金的浸出率 ,缩短浸出周期 ,降低 Na Cl耗量 ,具有一定的经济效益。
Extraction of gold from refractory gold ore has been studied.The effects of auxiliary leaching reagent(CaO 2) on leaching rate of gold are examined.The results show that leaching rate of gold increase,leaching period short and NaCN consumption reduce when CaO 2 being added in ore during leaching of gold using NaCN.
