particle size control on gold ores san antonio us; Products Application. Ball Mills - Mt Baker Mining and Metals . The capacity, or throughput, of a ball mill, is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind.

the impact of changes in particle size distribution on gold recovery from a low-grade ore using sodium cyanide as a lixiviant. A gold oxide ore from a Ghanaian mining operation was used in this investigation. The ore was milled and prepared into feed sizes ranging from 50–90% passing 106 µm and leached over 24 hours using conventional bottle ...
