Primary Secondary And Processed Mining Copper Ore All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market..

Types of Copper Deposits in the World INN. 23-5-2019 Primary and secondary ores; All copper mines have different mineral assemblages. The primary assemblage is the mineralization type that is most prevalent. Most types of copper deposits also have secondary ores, however, and they can add a great deal of value to a deposit.

2015-3-22 Now although primary porphyry mineralization generally has pretty modest grades subsequent weathering and erosion of the porphyry may pretty high grade secondary deposits of copper just below the water table. The oxygen above the water table allows primary copper sulfide such as chalcopyrite to break down to soluble copper salts.

2005-1-15 1. Introduction [2] A primary key to understanding past history of a volcano, and potentially future behavior, is interpretation of surface deposits. However, interpreting the origin of a blocky geologic surface is difficult, especially in instances where ground observations are not possible or where additional evidence that could provide spatial and temporal context for the deposit is ambiguous.
