how copper ore processed flow chart - cuppen-psychologen.nl. 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 useThe most common types of ore, copper oxide and copper sulfide, undergo two …
Process Flow. In copper matte smelting, fine and pulverized burdens (concentrate, solvent, dust, etc.) are uniformly mixed, dried (moisture less than 0.3%), and then stored in the feed bin at the top of a furnace. ... Figure 4 is the schematic diagram of Outotec flash smelting process control system. The main objects of control are copper matte ...

Hint: Blister copper is a metallic copper which has a black blistered surface, as we already know it is the product formed by converting copper mate and the product which is formed is 98.5 percent pure, also called Bessemer copper. Complete step by step answer: Let us first understand what copper matte is, - In simple words copper mate is a combination of copper …
Conventional converting of nickel-containing copper mattes in Peirce–Smith horizontal converters does not conform with the current environmental regulations. A global trend is to change over from conventional batch converting to a continuous converting process producing running slags. The main purpose of the continuous matte converting process is to …
