The unwanted waste rock (gangue) falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass.

The Extraction of Copper - Chemistry LibreTexts

Copper can be extracted from non-sulfide 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 sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction.

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% 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

How is Copper Made? The History of Copper

26-09-2016  Copper Concentrating: Once the copper ore is transported from the open pit, it must be cleansed of waste materials, such as dirt, clay and numerous minerals that bear no copper. This is called concentrating, and it’s usually accomplished through a method which entails crushing and grinding the ore in order to separate it from the waste materials (rock and other particles).

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

17-08-2020  Copper was discovered and first used during the Neolithic Period, or New Stone Age. Though the exact time of this discovery will probably never be known, it is believed to have been about 8000 bce. Copper is found in the free metallic state in nature; this native copper is the material that humans employed as a substitute for stone.

Copper: introduction to the chemical element -

The remaining ore is then heated in a huge furnace called a smelter, which burns off some of the remaining impurities and leaves a material called copper matte, which is at least 50 percent copper. A second heating process follows in which the copper matte is heated with silica and air to remove more waste, leaving a very refined material called blister copper that can be over 97 percent pure.
