精确化装补球法在狮子山铜矿的应用

针对云南狮子山铜矿选厂生产能力偏低及磨矿产品细度差等问题，应用精确化装补球法改进选厂两段球磨机的装补球方法。工业试验结果表明，新的装补球方法使磨机生产能力提高9%，磨矿产品细度提高7.88个百分点，磨矿介质单耗降低10.42%，全厂电耗降低10.81%，铜回收率提高2.98个百分点，可产生明显的经济效益。

Application of Accurate Ball Loading and Addition in Shizishan Copper Mine

In view of the low production capacity and poor grind fineness of Yunnan Shizishan Copper Concentrator, accurate ball loading and addition method was used to improve the ball loading and addition of the two-stage grinding. The industrial test results indicate that the adoption of the new method can bring a grinding mill production capacity increase by 9％, grinding product fineness improvement by 7.88 percentage points, unit consumption reduction of grinding media by 10.42%, power consumption reduction of the total concentrator by 10.81%, and increase of copper recovery by 2.98 percentage points, a remarkable economic benefit.
