Using Ball Mills to Extract Raw Gold from Ores

Using Ball Mills to Extract Raw Gold from Ores

In such a mill, a grid with openings used for unloading crushed material is located in the unloading end of the drum. To crush the gold ore in order to obtain pure gold, the large ore of gold is fed into a jaw crusher or mobile jaw crusher for the primary crushing process. The crushing process acts as a medium of screening the fine gold ore.
