The main aim of this study is to improve the processing capacity of the large-scale ball mill. Taking a Φ5.49 × 8.83 m ball mill as the research object, the reason for the low processing capacity of the ball mill was explored via process mineralogy, physicochemical analysis, workshop process investigation, and the power consumption …

A ball mill is a versatile and efficient tool for the grinding and blending of materials. Its working principle, based on impact and friction between rotating balls and the powder materials, results in the fine grinding and refinement of the material. The components of a ball mill, including the drum, grinding media, liners, and drive system ...

When the cyanide process was first introduced its application was confined to leaching, that is, treatment by percolation. By this method only such material could be worked as was sufficiently granular in texture to allow the necessary amount of solution to percolate through it in a reasonable time. By crushing the ore dry, it is ... ="Leaching …

For batch grinding, the artisanal ball mills are ideal for cyanide leaching. The mill-leaching process was successfully implemented in Portovelo, Ecuador. About 95% of the gold was leached from a pre-concentrate (with 17.3 g Au/tonne) obtained by grinding the ore in Chilean mill and concentrates gold in sluice boxes.
