To be applicable to this process the ores must contain copper minerals in sulfide form as mineral such as Chalcocite (Cu 2 S) Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore that might contain as little as 0.5 copper to form a concentrate

Non-Sulphide OresCopper

Three different stages are involved when extracting copper from non-sulphide ores. 1. Over a very long time and on a vast scale the reaction of the ore with a dilute acid (such as dilute sulphuric acid) produces an extremely dilute copper sulphate by solvent extraction. 2. a. By solvent extraction the copper sulphate is concentrated.

Copper Smelting Chemistry Tutorial

Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis ( electrowinning ) for low grade ores or by the carbon reduction method of smelting for higher

Nickel processingExtraction and refining Britannica

Nickel processingNickel processingExtraction 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 higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

given below are the steps for extraction of copper from

Given below are the steps for extraction of copper from its ore. Write the reaction involved. (a) Roasting of copper (I) sulphide (b) Reduction of copper (I) oxide with copper (I) sulphide

Extraction Of Copper Mining Concentration Smelting

Copper Mining The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. 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 Ore

What is Sulfide Mining Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area and by exposing sulfides to the air and water in our atmosphere sulfuric acid can be created — threatening to poison the nearby water

Copper Mining and Extraction Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores (11–14) but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Can copper be extracted from its sulfide ore by roasting

Your first equation is partially correct there is a slight mistake. Copper is found in the 1 oxidation state or cuprous form in its ores so the sulfide ore of copper known as copper glance has molecular formula of cuprous sulphide(Cu2S) . Bec

Metals extraction strikes gold IOM3

Speed of extraction is another area that Conti says cannot be beaten. We have been testing sulphide ores and are able to do the entire process from sulphur reduction extraction and recovery to powdered gold in an hour and a half. That same material would take 36 hours with cyanide which only gets an 83 extraction efficiency.
