particle size range gold ore - The grain size range of gold minerals is 0 ~ 800 μm, and the particle size distribution of gold particles is mainly concentrated in the range of 20 ~ 100 μ m( 69%) The gold particles less than 30 μm account for only about 8%, the recovery rate of that is low.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about

The Best Ore Particle Size of Ball Mill in Dressing Plant When the scale of ore dressing plant is 500 ton per day, the suitable particle size is 10-15 mm; The plant is 2500 ton per day, then size is 6-12 mm; and while the plant is 10000 ton per day, the size is 5-10 mm; and while the plant is 40000 ton per day, size is 4-8 mm. You can judge the model of ball mill you will need, …
