mining companies such as First Quantum Mining and Metorex2. The recent global financial crisis, and dramatic down turn in the price of copper has resulted in several other similar projects being suspended pending improved financial conditions. The region is still considered a valuable resource of base metals for future years.
Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is widely used in various applications, including …

The process of mining for silver is broken down into three steps: removing ore from the earth, breaking it down and then flushing the silver from ore. The first step involves drilling holes in the silver-rich areas geologists have previously pinpointed and then inserting dynamite sticks.
As high-grade deposits become exhausted, mining companies must process larger volumes of ore to extract the same amount of copper, increasing costs and environmental impact. Environmental concerns : Copper mining has significant environmental implications, including land degradation, water pollution, and greenhouse gas emissions.
