Investigation of the cyanide leaching optimization for ...

2018-9-29  Second, the fine product was subjected to the grinding process by vertical wet stirred ball mill, and the final ultrafine product was used as leach feed material. The leach feed material had about d 80 = 20 µm and d 50 = 6.02 µm particle size. Some important leaching parameters were optimized by using the ultrafine powder in the study.
