在过去磨矿实践中浮选精矿是在氰化物和石灰中细磨然后搅拌的。研究指出,在氰化物中磨矿,对回收率和氰化物用量是不利的。这是由于在密闭的磨矿机中减少了空气的缘故。在水中磨矿然后加入氰化物和石灰证明能成功地降低氰化物用量和增加金的提取量。试验工 Flotation concentrates have been finely milled and agitated in cyanide and lime in the past practice of grinding. Research indicates that grinding in cyanide is detrimental to recoveries and the amount of cyanide used. This is due to the reduced air in a closed mill. Grinding in water followed by addition of cyanide and lime proves to be successful in reducing the amount of cyanide used and increasing the amount of gold extracted. Test workers
