Depending on the distribution of gold and copper in the ore body, there may be the ability to selectively mine the deposit to produce one or more of the following feed streams: 1. Gold ore with low soluble copper (and thus amendable to direct cyanidation) 2. Copper ore. 3. Gold ore with high soluble copper

The specific gravity of copper ore ranges from 2.5 to 3.5, depending on the type and mineral content. Copper ore is a good conductor of heat and electricity. Copper ore is not highly reactive, but can react with strong acids and oxidizing agents. Copper ore can range in colour from metallic red to black, depending on the type and mineral content.

The diverse group of iron oxide copper-gold (IOCG) deposits has been one of the most contentious classes of ore deposits since its recognition as a new type in the mid 1980s to early 1990s. Central to the debates have been the issues of definition, classification, the roles of magmatic versus and non-magmatic sources of fluids and …

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
