In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat..

The following is a process of copper extraction from chalcopyrite ore into pure metal. While oxide ores can be processed using Pyrometallurgical techniques, Hydrometallurgical methods are more cost effective. The copper ore is crushed and ground before it is concentrated to between 20 and 40% copper in a flotation process.

1.2.1 Concentration by Froth Flotation (Chapters 3 and 4 Chapter 3 Chapter 4) The copper ores being mined in 2010 are too lean in copper (0.5–2% Cu) to be smelted directly. Heating and melting their huge quantity of waste rock would require prohibitive amounts of hydrocarbon fuel.

The effect of H 2 SO 4 concentration (0 (water)‒0.5 M) on copper extraction from the concentrate of flotation tailings was presented in Fig. 3. The copper approximately completely dissolved (98%) into water (H 2 O), whereas the iron leaching percentage reached 67%.

Copper process : The concentration of copper in ores averages only 0.6%, and most profitable ores are sulfides, especially chalcopyrite (CuFeS 2) and to a lesser extent chalcocite (Cu 2 S). These minerals are intense from crushed ores to the level of 10 to 15% copper by froth flotation or bioleaching.

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 ...

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. Concentration of the copper(II) sulphate solution by solvent extraction.

The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore: The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers.

In froth flotation process, the pH value of the pulp needs to be paid close attention to at all times. The pH value needs to be measured with a test paper every once in a while to ensure that the pH value remains at a stable value. And the pulp concentration and liquid level need to be stable, ensure scraping, to scrape out the full plate.
