Copper Smelting and Refining Process Pan Pacific

After about 10 days of electrolysis, the cathode is lifted out and stripped from the stainless steel plate, resulting in the completion of refined copper (with grade of 99.99%) as a final product. The refined copper is shipped in stacked bulks, which are 1m in length and width and approximately 80kg in weight.

Copper Production: How Is Copper Made?

2019-9-26  The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
