Beneficiation
A primary or jaw crusher is located at the mine site and reduces the particle diameter of the ores into <6 in. The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration. The second stage, grinding, is a wet operation which requires initial flotation and water to make a slurry.Web
