Concepción García-GómezMaria Dolores Fernández, in Comprehensive Analytical Chemistry, 2019. 7.1 Introduction. Cu and its compounds are naturally present in minerals, such as cuprite, malachite, azurite, chalcopyrite and bornite, and have long since been widely used.Cu is an essential micronutrient for plants, and plays a crucial role in plant growth and development.
Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
Nov 19, 2014· Copper extraction techniques refers to the methods for obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes.
The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth's surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods. Once it's removed from the earth, the concentrate is roasted at a temperature of 950 degrees ...

Mining How To Treat Oxide Ore; 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 Most of the copper ores mined today are oxide or sulfide ores.
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.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
· Best Answer: Most copper ores are sulphides and these are turned to the acid rain gas, sulphur dioxide, as the copper is extracted:this acid gas is the cause of a lot of enviromental damage(as at paris mountain as 'J' mentions above).The advantage of copper extraction is that it is a vital,and very profitable material bothh as pure copper in electical equipment and as less pure copper in ...
