18-10-2022Generally, it is gradually formed by the weathering of copper sulfide, and the minerals formed in this way are called secondary minerals. Copper ore contains more than 88.8% copper and is an important copper ore mineral. But due to its small distribution, it is only a minor copper ore in terms of utilization.

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is

The Mining Process. 1. Mining – Open Pit and Underground — To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

13 Copper or 'red metal' can be combined easily with other metals to form alloys. An average home could contain up to 180kg of copper. One of the most important aspects of copper is that it can be recycled easily, and 80% of copper ever mined/produced is still in use. The electric vehicle (EV) boom has bolstered the demand for copper significantly.
