The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral ore.
Extracting Copper from its ore Low-grade ore is piled on specially treated impermeable ground for ease later to drain away the Cu ion solution. The bacteria can then be sprayed on requiring acidic conditions, a supply of Fe2 and S2- ions, oxygen carbon dioxide and nitrogen and phosphorous containing nutrients.
Jan 01, 2018 Therefore the copper ions obtained from 6.0 g of the ore were later reduced by hydrazones species prepared in situ. However, the mass of the ore used varied depending on the composition of copper in the ore. 184.108.40.206. Kinetics of the extraction and in situ reduction of copper using chicken waste solution
Sep 26, 2019 Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 copper.

processes using dilute sulphuric acid. The first process, vat leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of high-grade oxide ores was decreasing and vat leaching was on the decline.
copper, which are also found in ore deposits of copper, can be converted into a soluble form by leaching, where the chemistry of the process is simple. Copper carbonates and oxides, are present mainly in the oxidation zone - oxide hats above the sulphide deposits. Sulphide copper

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 SO 2 2CuSO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister Copper
