The process of extracting copper from copper ore varies depending on the type of ore and the desired purity of the final product. However, generally, the process involves four main steps:...
Four factors are essential to the successful leaching-of any copper-bearing ore: A solution that will attack the copper minerals must get into the body of the ore particles the copper minerals must be dissolved …
At present, this crushing process is widely used in the new cobalt beneficiation plants in Congo (DRC). Cobalt extraction process The Katanga copper-cobalt ore belt in Congo (DRC), with a length of 300km and a width of 100-150km, runs from Kolwezi in the northwest to Lubumbashi in the southeast to the Zambian border.
In some cases, primary crushing takes place underground; in others, a ramp and trucks carry ore to the surface. Extraction and refining The extraction of copper from ore is normally carried out in three major steps.
The first step in the extraction process is mining. Copper ore must be mined using open-pit or underground mining methods. After the copper ore is mined out of the …

The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation.
Many metals can be reduced and extracted in a school laboratory. The easiest are iron, copper and lead. Over several lessons students can be taught how a metal is extracted and reduced from its ore. As you introduce each new example, increase the complexity of the chemistry. This process will continue during GCSE and A-level studies.
