Copper mining. From ore to copper.

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 minerals are

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Extraction Of Copper Mining, Concentration, Smelting

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.

Smelting and Refining Operations

When sufficient copper has been cemented out, the copper rich iron is put into the smelter together with the ore concentrates for copper recovery via the pyrometallurgical route. In the SXEW process, the pregnant leach solution (PLS) is concentrated by solvent extraction, which extracts copper but not impurity metals (iron and other impurities).

12.3 Primary Copper Smelting

Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

Copper Mining and Processing Everything you Need to Know

The Copper Mining Process. During the Industrial Revolution, coal and steam powered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week. At the beginning of the 20th century, the annual worldwide copper demand was at half a million tons.

Use ore sorting equipment to concentrate ores and cut

Use ore sorting equipment to concentrate ores and cut process costs. The entire processing line can be planned in semi mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on site. Additionally, higher prices can be achieved with the concentrate since the ore content is considerably greater.

Copper Mining and Extraction Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
