Copper Ores and Copper Mining Process - Naipu Mining

Copper Ores. Copper occurs in two different mineral groups: sulfide ores, oxide ores (carbonate minerals and silicate minerals), and both ore types can be economically mined. Copper sulfide ores are the most profitable types of ores as they have high copper content, and the copper can more easily be separated from the unwanted minerals.
