Open pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using open pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time.
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. The stripping pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
The Company is making significant progress and is on target to re start copper production in August 2020, following the temporary suspension of copper production due to the impact of COVID 19: Mine Development: Multiple key milestones havepleted ahead of schedule on final configuration of

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
As in all mining operations, the ore must usually be beneficiated concentrated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals such as chalcopyrite, th

Large open pit copper mines can produce up to a million tons of waste and ore per day and can be mined at that rate for decades. Quarrying is similar to open pit mining except the termmonly applied to the extraction of dimension stone and aggregates. Fewer benches are required in quarrying than in open pit metal mining in quarrying, most of the material extracted is marketable. In

Tailings are finely ground rocks and other mineral waste as a result of mineral processing. Due to the way minerals are processed, tailings can contain concentrations of processing chemicals. This can make mine tailings an environmental concern, so proper transportation and disposal are crucial. Consequently, the next step is to pump mine tailings away with slurry pumps into tailings ponds
Haul trucks transport the ore from open pits or underground operations to processing operations. Some ores may be stockpiled for later processing. Rock that is not economical to mine is stored in waste rock storage areas. The grade and type of ore determine the processing method used. Additionally, the geochemicalp of the ore, including its hardness, sulfur
The ore is removed from the ground in either open pit or underground mines. Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open pit 90 of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.
