China Gold Ore Mineral Processing Machine Ball Mill. 8474202000. product description. ball mill is the key equipment for smash the materials after they are primarily crushed. ball mill isgenerally used to grind material 14 inch and finer, down to the particle size of 20 to 75 microns. ball milll is an efficient tool for grinding many materials into fine powder.

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.

Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 % of the gold, under the condition that the ore size is 80 % < 75 µm (Joe Zhou, 2004).
