copper ore how to extract

copper extraction and purification - chemguide

Extracting copper from other ores. Copper can be extracted from non-sulphide 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 sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction. The very dilute ...

Copper Mining and Extraction Sulfide Ores

This is either sold for industrial use or used to extract oxide ores of copper by leaching. Stage 4: Smelting with fluxes The calcine is heated to over 1200 °C with fluxes such as silica and limestone. The calcine melts and reacts with the fluxes. Some impurities form a slag (such as FeO.SiO 2), which floats on the surface of the liquid (like oil on water) and is easily removed. (Courtesy of ...

Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing ...

An ore is a rock that contains enough metal to make it worthwhile extracting. The main copper ores are: chalcopyrite bornite malachite. Grinding: The ore is crushed then ground into powder. Concentrating: The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting: This is where the chemical reactions start.

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Copper Smelting Process - Furnaces Used, By-Products,

Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting. The ore is crushed, screened, and washed before being further processed ready to supply the smelting furnace.

Copper Smelting Chemistry Tutorial

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 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores (usually higher grade ores) by direct ...

Why do we extract copper from low grade ores?

Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate. Slow process - it can take years to extract 50% of the metal from a low grade ore.Energy is needed in the elctrolysis step. Then, the copper will be extracted from the leachate by electrolysis or scrap iron.

Where copper ore has been mined there are areas of land that contain very low percentages of copper compounds. One way to extract the copper is to grow plants on the land. The plants absorb copper compounds through their roots. The plants are burned to produce copper oxide. The copper oxide produced from plants can be reacted to produce copper or copper sulfate solution, as shown in
