Mill grinding WikipediaCopper Mining and Processing Processing of Copper Ores

A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting Such comminution is an important unit operation in many processThere are many different types of mills and many types of materials processed in them Historically mills were powered by hand eg via a hand crank working animal eg horse mill wind or water Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday useThe most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively
