·Typical equipment for crushing to about 20 cm are gyratory and cone crushers Then wet grinding Finland Flash smelting has been the most widely adopted copper matte smelting process since 1970 More than 40 furnaces have been installed to replace reverberatory furnaces or at new smelting operations Nowadays the Outokumpu
·The process varies slightly depending on the type of ore that is being mined Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 8 inches water and steel balls and further reduce the particles to the optimum size for the flotation process which follows About 80% of copper from ore is generated
3 ·smaller sizes Depending upon the feed and product particle size the crushing operation can be classified as follows 1 Primary crushing The feed material is usually the run of mine 2 Intermediate crushing or secondary crushing The feed material is usually product of a jaw crusher 3 Fine crushing or coarse grinding
·1 Introduction Polysilicon is one of the basic raw materials of electronic information industry and emerging energy industry [1] [2] As one of the most dominant materials for the photovoltaic industry more than 80% of commercial solar cells are made of polysilicon [3] [4] Therefore how to assure the manufacturing quality and reduce the
