Copper Ore Types Sulfides vs. Oxides INN

Copper Ore Types Sulfides vs. Oxides. Both ore types can be economically mined, though they are processed in different ways. Copper sulfide ores are typically the most profitable copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted minerals. However, copper oxide ores are more abundant.

Tungsten enrichment in the South China type massive

Abstract. Tungsten is a characteristic element of the South China type massive sulphide deposits that were formed on the continental crust. The high contents of tungsten in these deposits are attributed to the primary enrichment of this element in the basement sequences of the region, providing an indication of the tungsten enrichment in the continental crust.
