A plant is under construction in the once-thriving copper-mining area of the Northern Cape that will make use of a new low-power South African-developed technology that is able to process stranded copper ore concentrates into 98%-pure copper crystals without the need for any smelting.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and …
As the copper is more soluble in the organic layer than the aqueous, it enters an organic-copper solution and is separated. Sulfuric acid is added to strip the copper from the organic solvent into an electrolytic solution. In the electrolytic process, called electrowinning, the copper plates out onto the cathode.
Silver processing: Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration,
A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").

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 and is called copper concentrate.
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
Buzwagi Mine can process 4.4 million tonnes of open pit ore per year which is much lower grade and, through flotation, remove most of the waste rock and concentrate the minerals into approximately 25,750 tonnes of concentrate containing gold and copper. That is nearly a 200 times reduction in mass which then makes the

How Iron and Steel Work - HowStuffWorks. The refining of iron ore is one of the most historically significant achievements of all time. Find out how iron gets turned into steel and what it's used for.
If the gold concentrate has copper, silicon can form alloys with copper easily avoiding or minimizing the brittle effects. Other problem with silicon is the grain size, it tends to grow. When some corners are brittle, they were cause by silicon.
Copper ore that is rich in sulfides is processed via pyrometallurgy, while copper ore that is rich in oxides is refined through hydrometallurgy. Read on to learn more about copper-refining processes.
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. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

In the hydrometallurgical processes, the ore or concentrate is brought into close contact with a leach solution (frequently sulfuric acid) that dissolves the copper and leaves a residue of gangue (and frequently precious metals).
For special native copper bearing ore bodies or sections of ore bodies rich in supergen native copper, this mineral can be recovered by a simple gravity circuit. Application. Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide.
flotation of the ore pulp, which exploits the different surface properties of the sulfidic copper ore and the gangue [46]. The hydrophobic sulfide particles become attached to the air bubbles, which are stirred into the pulp, rise with them to the surface of the pulp, and are skimmed off as a froth of fine concentrate.
This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6. Refining. Copper from the smelter is melted and cast as anodes, the solution from the solvent extraction ...

Copper in the feed was, on average, 63 percent recovered into a copper concentrate grading 24 percent copper and 1.6 percent lead. On average, lead in the feed was 36 percent recovered into a concentrate grading 55 percent lead. Only 0.3 percent of the copper in the feed was recovered to the lead concentrate.

The slurry of water and pulverized ore is mixed with milk of lime to raise the pH and small amounts of special reagents: a frother to make bubbles, and a collector chemical that causes the copper minerals to stick to those bubbles.
In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.
