Copper holds as much as 90 percent of new copper value. Mini 400 type (the smallest) copper wire granulator can handle up to 80-100kg per hour. This machine is really popular in homemade and small scale recycling business as it's the ideal system to process the cable wire from scrap metal.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
26-08-2015· Copper Mining & Extraction Process Flow Chart. This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).
