Mining Industry Types and Distribution of Copper Ore in

In addition to the abovementioned types, there are vein type, natural copper type, carbonate rock type and skarn types, which together account for 36% of the world’s total copper reserves For China, the skarn type is very important to the copper industry, Northern Chile has some of the largest copper (± gold ± iron) deposits in the world These copper deposits formed from a combination of factors, but are generally associated with intrusiveextrusive magmatism and tectonic activity on the western boundary of the South American plate (Davidson, 1987; Camus, 1990; Sillitoe and Perelló, 2005)The Andes, copper mines and volcanoes of Chile There are two distinct types of copper deposits: sulfide ore and oxide ore Currently, the most common source of copper ore is the sulfide ore mineral Types of Copper Deposits in the World An Investor's
