Ore Dressing Ore Use Bomag Milling

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation

    Oct 10, 2017 How to use the ball mill to control the grinding fineness? Ore Milling Equipment fineness is one of the many factors that affect the ore dressing index. The size of the grinding fineness directly affects the grade of concentrate and the recovery rate of the product, which can directly reduce the beneficiation cost and improve the economic benefit of the plant
