The aim of this paper is to assess the effect of microwave treatment on copper sulfide ore for ball milling and bed breakage. Liberation analysis of ground products in eight size fractions showed that microwave pretreatment liberated more chalcopyrite particles from the bed breakage product than the ball mill product. In bed breakage, microwave pretreatment caused a 2% increase in chalcopyrite liberation on average. Microwave pretreatment produces more elongated particles in ball milling and more rounded particles in bed breakage, respectively. Microwave pretreatment produces coarser chalcopyrite particles with a wide range of sizes. This effect is more significant in bed breakage compared with ball milling. Micro-flotation test results showed that in ball milling, treated and untreated materials have similar metallurgical performance and there is a little difference (1%) between the average Cu recovery values. However, in bed breakage, the average recovery for the treated materials is about 5% higher than the untreated materials.

本文的目的是评估微波处理对硫化铜矿球磨和破碎床的影响。八个粒度级分的磨碎产品的释放分析表明，与球磨机产品相比，微波预处理从床破碎产品中释放出更多的黄铜矿颗粒。在床破损时，微波预处理导致黄铜矿释放量平均增加 2%。微波预处理分别在球磨中产生更多细长颗粒和在床破碎时产生更多圆形颗粒。微波预处理会产生较粗的黄铜矿颗粒，其尺寸范围很广。与球磨相比，这种效果在床层破损时更为显着。微浮选试验结果表明，在球磨中，经处理和未经处理的材料具有相似的冶金性能，平均铜回收率值之间存在微小差异（1%）。然而，在床破损时，处理过的材料的平均回收率比未处理的材料高约 5%。
