extraction of copper from ores

Aug 21 2020 · Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore Sulfide ores such as chalcopyrite CuFeS2 are converted to copper by a different method from silicate carbonate or sulfate ores Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper

This process uses aqueous waterbased solutions to extract and purify copper from copper oxide ores at ordinary temperatures usually in three steps heap leaching solvent extraction and electrowinning Heap Leaching is the process of using percolating chemical

Jan 11 2018 · 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

Web search hints Porphyry copper – Nazca subduction – Global volcanism smithsonian Copper can be extracted from its ore by Underground sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore Open pit 90 of ore is mined by this method

Extracting copper from other ores Copper can be extracted from nonsulphide 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 copperII sulphate solution

Copper Ores An ore is a rock containing enough valuable mineral to make it worth extracting In the case of copper it is worth extracting when there is about 2 kg of copper per 1000 kg of ore 02 Copper minerals are found in over one hundred varieties although only a few have been worked for copper on a large scale

Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water to which surfaceactive agents have been added

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

Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water to which surfaceactive agents have been added

The extraction of copper from ore is normally carried out in three major steps The first step mineral processing is to liberate the copper minerals and remove Live Chat Innovations Introduction to Copper Mining Extraction Copper minerals and ores are found in both igneous and sedimentary rocks Mining of copper ores is carried out

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite azurite and chrysocolla but these acids have but little effect on sulphide copper

Extraction of Metals Extraction of Copper Copper is sometimes found as native metal Copper ores include copperII oxide and copperII sulfide CopperII oxide can be reduced by reaction with carbon Some copper ores may contain only small amounts of copper These are called low grade ores and have less than 1 copper but they are still used because copper is so valuable

Copper Mining and Processing Processing of Copper Ores Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and

Extraction and refining The extraction of nickel from ore follows much the same route as copper and indeed in a number of cases similar processes and equipment are used The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production

Extracting iron and copper Ores It is more expensive and wasteful to extract a metal from a lowgrade ore but most highgrade ores have already been used Extraction methods
