The copper (Cu) mining and mineral processing industry plays a vital role in economic development and job creation in addition to supplying invaluable resources for modern civilization (Farjana et al., 2019).Most importantly, this sector must meet the growing demand for primary Cu, even as society achieves greater efficiency by reducing extraneous uses, reuse, …
Open pit mining is a technique used to extract copper ore near the earth's surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to …
The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to the metal by the …
Copper mining is an energy-intensive process that requires significant amounts of electricity and fuel. The extraction and processing of copper ore involve various stages, such as drilling ...
Underground Mining, on the other hand, is employed when copper deposits are located deep below the Earth's surface.This method involves creating a network of tunnels and shafts to reach and extract the ore. While underground mining is more expensive and complex than open-pit mining, it is more suitable for high-grade ores found at greater depths.
Copper ore is extracted using two basic methods of mining - open pit or underground mining. 3. Processing of Copper Ore. The first step in processing the ore removed from the mine is to …
The smelting process at Kennecott produces copper, gold, silver, platinum, palladium, lead carbonate, and selenium. Molybdenum production details.
