New ways of extracting copper from low grade ores are being researched One of these is called phytomining What does phytomining involve Using high powered lasers to blast the copper from the low grade ore Using plants to absorb the copper compounds from the ores then burning the plants
The copper ores were mined from copper sulphide deposits where the upper layers contained mostly copper oxide and copper carbonates Continuous mining extended the amount of sulphide and therefore the ore needed to be roasted oxidized prior to extracting a copper metal from an ore by heating Chen 2022 Oudbashi and Wanhill 2022
The ore is then ground finely before the copper bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material or gangue Depending on the type of copper bearing minerals in the ore and the treatment processes used the concentrate typically contains between 25 and 30 copper
There are many sources to increase value in an integrated mining metallurgy context The optimal strategy for concentration of minerals from the ore is one of these sources The elements of mining metallurgy operations from resources infrastructure mining site processing and metallurgy are mutually dependent and reinforce and interact positively with each other to generate a

How is lead mined and extracted Lead is extracted from ores dug from under ground mines Next the lead powder is put through a flotation process that involves mixing the lead ore with water the addition of pine oil and the introduction of air bubbles and agitation which forms an oil froth containing the lead ore on the surface
Copper Mining and Extraction Sulfide Ores 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 Ores near the surface can be quarried Contact
Jul 28 2022The rock is then crushed by powerful machinery Metal is extracted from the crushed ore by one of two major methods smel ting or electrolysis Smel ting uses heat to separate the valuable metal from the rest of the ore Smel ting usually requires a reduction agent or another chemical to separate metal from its ore
This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores in four basic steps 1 froth flotation 2 thickening 3 smelting and 4 electrolysis
Aug 9 2022Copper from Cu2S can be obtained from its ore simply by heating in air I First step is the heating of sulphide ore of copper in the presence of an excess of air This process is known as roasting II The second step is the self reduction of copper How do you get copper ore Look for igneous rocks
