The purpose of smelting is to enrich most of the copper in the copper concentrate in the matte phase. The gangue, oxides and impurity elements were combined in the slag phase to completely separate the copper matte in the slag phase. In this paper, a mathematical model based on the optimization of copper concentrate cost and the …

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

This will cause a gradual decrease in the copper concentrate grade of traded concentrates, unless efforts are made to make concentrates mineralogically cleaner; that is, the proportion of copper sulfides would have to increase above the current level of 55–60% by removing more iron sulfides and non-sulfide gangue minerals. To achieve this ...
