Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.
04/12/2019 · Most forms of surface mining use heavy equipment such as earthmovers to remove the overburden before bucket wheel excavators or dragline excavators extract the mineral. Surface mining is done in five ways: Strip mining – Strip mining is the most common surface mining method used to mine coal and lignite. The process is done by removing a ...
The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The loion and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
It has been crushed to threeinch size. After weighing and sampling the first operation is to separate the nickel and copper sulphides. This is done by making use of the fact that molten sodium sulphide is completely miscible with copper sulphidc and completely immiscible with nickel sulphide, so .
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of ...

Copper extraction is distinctly profitable when the selling price of copper is above 6/kg. It is unprofitable for some operations when the selling price falls below 3/kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid2011 was ∼9/kg.
Copper is a valuable asset to us and has been used for over 5000 years. It is used in plumbing, electrical wires, money (alloys), jewellery, ornaments and many other different objects. Copper comes from most continents in the world, but the major contributor to copper is Bingham Canyon, USA; it is one of the largest open cast mines in the world.
Concentrating. The copper ore usually contains a large amount of dirt, clay, and a variety of noncopper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.
types of crushers used to extract copper. Primary coal crusher: Used for larger coal size. The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher.

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24
A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. A typical copper ore contains between % and % copper.
