Using Ball Mills to Extract Raw Gold from Ores ...

Jun 14, 2018  Thereafter, the gold ore is transferred to a multi-cylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding. From the ball mill, the gold ore powder is subjected to the process known as beneficiation for further crushing before classification and floatation processes.
