Volcanogenic Massive Sulphide Deposits: Long Term

Volcanogenic massive sulfide deposits are major sources of copper and zinc, and contain significant quantities of gold, silver, lead, selenium, cadmium, bismuth, tin and more. Volcanogenic massive sulfide (VMS) deposits are as impressive as they sound. Formed as far back as 3 billion years, these geological marvels represent a large portion of

Apr 29, 2016· The mill feed is supplemented with sulphide ore conveyed from Coldelco's nearby Radomiro Tomic mine. Radomiro Tomic is primarily a heap leaching operation which processes oxide copper material. As a cost saving measure, Radomiro Tomic does not have its own sulphide processing plant but instead conveys sulphides to Chuquicamata.

MINING

What's in an Ore? There are many types of Copper Ore found throughout the world. About 80% of all Copper extracted comes from Sulphide Ores. A typical Ore contains only 0.5% to 2.0% Copper. It is a measure of the value of Copper that it is worth extracting it from such small concentrations. The Ore is a mixture of minerals and rock (called Gangue).
