Basics of an open pit mine
Several benches may be in operation simultaneously in different parts of, and at different elevations in the open pit mine. 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.

Copper Smelting Process
· Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of % purity. Copper can be recycled indefinitely without the base metal being compromised ...

Leaching Process
The process of heap leach mining occurs when the ore is placed on a liner and the chemicals are then added to it with the help of the drip system. This process is extensively used in today's largerscale operations of mining since it generates the desired concentrates at a comparatively lower cost when compared to the traditional methods of processing like vat leaching, agitation, and flotation.

Focussing on the gold industry, Gekko replace highenergy whole ore treatment of gold by carboninleach (CIL) methodologies with beneficial lowenergy process solutions. Harnessing both gravity separation and floatation, as well as dramatically reducing the initial mass to be processed by preconcentration, Gekko flowsheets increase the grade for downstream intensive processing.

How iron is made
The Ore Extraction and Refining Process Before iron ore can be used in a blast furnace, it must be extracted from the ground and partially refined to remove most of the impurities. Leaning on his long tongs, this young iron puddler's helper posed for this photograph in the early 1860s, when the Sons of Vulcan was a young union.

Environmental Risks of Mining
There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA], 2005). However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well.

Iron Ore Reduction
Simulation results indied that the 2step process would use less fresh hydrogen than the 1step process at the same operating condition. This is because the 2step process requires less fuel than the 1step process as the water vapor generated by combustion in the ironmaking reactor is smaller, which decreases hydrogen required to satisfy the specified excess driving force.
