Copper Mining and Processing: Processing of Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,

Ball Mill: Operating principles, components, Uses

Disadvantages of Ball Mills. 1. Contamination of product may occur as a result of wear and tear which occurs principally from the balls and partially from the casing. 2. High machine noise level especially if the hollow cylinder is made of metal, but much less if rubber is used. 3. Relatively long milling time. 4. It is difficult to clean the machine after use.
