Energy and Environmental Profile of the US Mining Industry 51 Process Overview 511 Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations In 2000, the principal mining States, in descending order, Arizona, Utah, New Mexico, and Montana, accounted for 99 percent of domestic .
extraction of copper from its ore extraction of copper from its ore XSM excellent mining crushing machinery products or production line design, the company is committed to building the Chinese brand mine crushing and processing machinery, mainly crusher, mill, sand making our products (extraction of copper from its ore) in more than one hundred of the worldsales of countries and regions
About 80% of all copper extracted comes from sulphide or A typical ore contains only 05% to 20% copper It is a measure of the value of copper that it is worth extracting it from such small concentrations The ore is a mixture of minerals and rock (called gangue) The most common copper ,
Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time Copper can then be extracted from the copper(II) sulphate solution But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means
Most of the copper ore produced in Australia comes from underground min At a few Australian mines, copper is leached from a copper oxide ore to produce a copper-rich solution that is then treated by solvent extraction and electrowinning to recover the copper metal
