There are several methods for gold ore beneficiation, including gravity concentration, flotation separation, cyanide process and etc.. We can choose different method according to different actual situation. In some situations, two or above methods can be adopted.
Generally, if the gold content in the raw material is high, the effect of gravity concentration is better. The main machines of this process include
crusher, ball mill, shaking table/spiral chute and etc.. If the gold content is low, we usually adopt flotation separation. Besides crusher and
ball mill, the important machine in this process is flotation machine.
