Copper mining. From ore to copper.SchoolScience
· 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). The most common copper

· Copper mining. The main stages. Copper minerals and ore are found throughout the Earth s crust. They occur in both sedimentary and igneous rocks. The outer 10km of the crust contains 33g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock. Copper mines are only set up where there is more than

Processes. Copper is found in natural ore deposits around the world. This page explains the production route taken from extraction of 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.
Chat OnlineInnovations Introduction to Copper Mining Extraction
· 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.

That there are underlying reasons for lack of success is apparent to anyone familiar with the host rocks in the field. The rock-types commonly regarded as favorable are described. The observation that Cu mineralization is virtually confined to the fragmental flow-tops is related to the ratio of flow-top thickness to the total thickness of an individual flow termed the skin ratio.

· Copper Chemistry. " For nearly 5000 years copper was the only metal known to man. Today it is one of the most used and reused of our modern metals." Humans first used copper about 10 000 years ago. A copper pendant discovered in Northern Iraq is thought to date back to around 8700 BC.
Chat OnlineSelective copper diffusion into quartz-hosted vapor
Recent experimental studies have raised concerns that Cu concentrations in quartz-hosted fluid inclusions from magmatic-hydrothermal ore deposits do not represent pristine concentrations in the trapped fluids but are modified by post-entrapment diffusional exchange through the host quartz. New microanalyses of fluid inclusions hosted in topaz show significantly lower Cu concentrations in

How is the mineral separated from the ore one method is froth flotation- ore is mixed with water to form a slurry chemicals and air bubbles are added (the minerals will float to the top by the air bubbles where they can be collected) What type of mining removes the top layers of soil and rock horizontally to expose the resource strip mining.

· The unwanted waste rock (gangue) falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25 copper
