Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy

Copper ores generally contain sulfides or oxides and copper in the 0 5 to 2 0 percent range Because of the greater value of copper metal, refining ores at these levels is profitable Refiners crush copper sulfide ores mechanically and use froth floatation to bring copper containing particles to the surface of a water solution The material is then heated to over 930 degrees Fahrenheit to burn

Whatever method is used to manufacture copper from its ore, its final purification is by electrolysis Figure 6 Slabs of impure copper blister copper, together with thin sheets of pure copper metal or stainless steel or titanium are immersed in a solution of copperll sulfate 0 3 mol dm 3 and sulfuric acid 2 mol dm 3

Ways to Separate Metal From Ore Sciencing Jan 9, 2018 The process of separating a metal from its ore is known as smelting to the high tech, and are applied to a variety of materials, including aluminum, iron and copper

methods used to separate copper ore from other Copper Ore Types: Sulfides vs Oxides Investing Apr 21, 2011 Depending on which minerals the copper is bound to, the rock is processed in different ways in order to extract the valuable copper

Copper is much rarer, but fortunately can be found in high grade ores ones containing a high percentage of copper in particular places Because copper is a valuable metal, it is also worth extracting it from low grade ores as well

This method is used in copper and nickel production Iron, ferrochromium, lead, magnesium and ferrous compounds are produced by reduction of the ore with charcoal and a flux limestone, the smelting process usually taking place in an electric furnace See also the Iron and steel industry chapter Fused salt electrolysis, used in aluminium production, is another example of a

Methods of extraction Many metals are found in the Earth's crust as ores An ore is usually a compound of the metal mixed with impurities When the metal is dug up, a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is The more

After this stage the enriched ore now contains about 25 copper by mass and is called copper concentrate It is valuable enough to ship to other plants and other countries for processing For example China, Germany and Japan are major copper producers that use

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes, which will ultimately be made into products for everyday use

Copper extraction refers to the methods used to obtaining copper from its ores The conversion of copper consists of a series of chemical, physical, and electrochemical processes

The single most important method used for the recovery and upgrading of sulfide ores, thats how G J Jameson described the froth flotation process in 1992 And its true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are increased by

In modern world copper is produced by processing the ore to obtaining copper concentrate which is a major raw material for smelters In general, the technological process involves drilling, mining, ore processing, ore flotation for concentrate recovery and rehabilitation of damaged areas

For example copper acetate is reacted with chemicals to separate the copper, ore and residue This mix is reduced, which involves placing it under extremely high temperatures, injecting a reagent such as hydrogen or carbon dioxide, and melting away the metal
