Extraction of Copper Oxide (I): Purified CuSO4 Solution
Heating and melting are frequently used to extract copper (Cu) from its parent ores [1,2,3,4].Roasting, smelting, and conversion are the three phases of the heating and melting process for primary copper ores [5,6,7,8,9,10,11].Significant amounts of copper are lost as dust in the first and second phases; this dust is referred to as waste copper dust (WCD).
