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.

Milling. Uranium milling involves extracting uranium from mined ore. The ore is crushed into sand size particles and the uranium is leached out. The uranium then is precipitated out of the leaching solution and dewatered, dried, and packaged. Through the extraction process, uranium is concentrated into a product referred to as "yellowcake."
