Ultra-fine grinding of the flotation rougher concentrates was employed for selected tests to understand leach extractions of the concentrates. The primary grind sizing, for Flowsheet 2, was a nominal 50um P80, two tests were conducted at a coarse crush size of 3.350mm P80 to assess heap leach amenability of the selected composites.

Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the ...
