Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.
As a pure natural stone with high usage value, river gravel is formed in the long-term impact, squeeze and friction function. River gravel generally shows the color of black, white, yellow, red, green gray, etc.

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
Recycling of copper is based on a large variety of raw materials ranging from lowgrade copper scrap containing only a few percent Cu to very highgrade copper as well as pure copper close to 100 Cu Table 71 Thus there are several options for recycling processes within both primary plants and secondary plants treating only scrap material
