what are the stages of extracting minerals Description

Copper mining. The main stages. -

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 5kg of copper per tonne of rock (0.5% by mass). Ideally, the

However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminium is bauxite - which contains from 50 - 70% of aluminium oxide. Note: We always treat bauxite as if it was aluminium oxide for chemistry purposes, although it is actually more complicated than that in reality. Copper is much rarer, but fortunately can be found in high-grade

Mineral Extraction - an overview | ScienceDirect

Mine wastes are produced at two stages during the mineral-extraction process: during mining, when waste rock or spoil is produced; and during further processing of the materials extracted, which creates a further set of mineral wastes, generally much finer than simple spoil and referred to as tailings.

The Extraction of Copper - Chemistry LibreTexts

Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper (II) sulfate solution. Concentration of the copper (II) sulfate solution by solvent extraction.

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is, where

Copper Mining and Production Processes Explained

In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and iron sulphides. These account for about 80% of the world's known ores.
