Wet Ball Mill for Metal Ores and Non-ferrous Metals Wet

Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid (water or anhydrous ethanol) to grind materials. Unlike dry ball mill, wet ball mill adopts the wet grinding method. The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding. This method can effectively reduce the chance of the material properties changing

Some impurities form a slag (such as FeO.SiO 2), which floats on the surface of the liquid (like oil on water) and is easily removed. (Courtesy of Xstrata.) The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores.
