Extracting copper from other ores 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.
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 concentrate from around the world.

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.
Here advantage is taken during the extraction of other precious metals such as f.e. copper or zinc where also small quantities of gold are found in the extracted rock. In the process of the electrolytic cleaning of the rock sludge the anode activates the precious metal bearing rock sludge.
Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.
The Sceresini process on the other hand is a two-stage process that utilizes the lower pH limitations of hypersaline water to enhance copper adsorption, with copper being removed in the first stage, thereby allowing optimal cyanide concentration for maximum gold extraction and adsorption after copper …
