Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.

2 Hydrometallurgy is the recovery of metaIs from ores using water-based solutions. As early as 6000 B. C., native copper–the pure metal—was foundas reddish stones in the Med- iterranean area and hammered into utensils, weapons, and tools. Around 5000 B. C., artisans discovered that heat made copper more malle-able.

To put it simply, a mining company pays a royalty on a monthly basis, which is a percentage of its sales. If the price of copper is $6 000 per tonne, and the royalty rate is 7.5%, a mining company will receive a maximum of $5 550 for that tonne, with the balance (i.e. the $450) being paid over to Government as a royalty.

The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance.

In addition, huge quantities of copper are known to exist as "deep-sea nodules" scattered on the ocean floor, although high recovery costs has thus far prevented their commercial exploitation. Chile and the USA are, respectively, the world's two leading copper-producing nations, Chile having overtaken the USA in the early 1990s.

Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today's price, US$5,842/tonne, if that material could be reprocessed and an extra ...

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).

Mining copper 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 (ndida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.
