Open Cast Mining Advantages. And it’s here that surface mining affords the selectivity of what is processed and what is the waste at the time of the mining. Examples of disseminated ore deposits are porphyry copper deposits, formed by circulating metal rich fluids in fractured igneous rocks, often resulting in a stock work vein arrangement.
Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.
Opencast mining, also known as surface mining or strip mining, has disadvantages that include disturbance of the environment and local ecosystems, exposure of radioactive elements and contamination of freshwater sources.
