Copper Mining and Extraction Sulfide Ores

About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and

PDF 1 Froth Flotation - Fundamental Principles

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 - 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

Flotation of oxidized copper ores - Inspiration

In accordance with the invention, copper is recovered from an aqueous pulp of an ore containing both oxidized and sulfide copper minerals by continuously monitoring the EMF of the pulp, and adding a water-soluble sulfide to the pulp in an amount from 0.05 to 7 pounds of containd sulfur per ton of ore whenever and for so long as the pulp EMF is above about -30 millivolts with reference to a standard silver-silver

Copper's Role in a Low Carbon Economy

Maximizing copper production will also likely be critical to meeting the needs of a low-carbon future. While smelting is still a primary method of copper ore beneficiation, advancements in solvent extraction – electrowinning, or SX-EW has opened up opportunities for previously uneconomic ore bodies to be efficiently processed.

Flotation Developments & Best Practice - International Mining

In this case, the hypogene ore carried a range of copper sulphides including chalcopyrite (26.3%), bornite (50.9%), and chalcocite (17.1%), with minor covellite, occurring at a very small mean grain size of 7-27 μm. It would be uneconomical to grind the ore down to these sizes to deliver good liberation before flotation.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
