压缩空气加过氧化钙在金氰化中的协同作用

Application of Cooperation of Conducting Compressed Air and Adding Calcium Peroxide in Gold Cyanide Leaching

研究了湖南某金矿氰化浸金工艺，结果表明，通压缩空气同时添加过氧化钙的浸金效果比单一效果好，提高Ａｕ的浸出速度和浸出率，并降低过氧化钙的用量。

Cyanide leaching of gold from an ore from Chengzhou, Hunan was studied. The results show that the recovery of gold by using the cooperation of conducting air and adding calcium peroxide than by using the single one. The leaching rate and recovery of gold can be increased, at the same time comsumption of calcium peroxide was reduced.
