Open Pit Mining Most active tungsten mines are of moderate scale (production of a few 100,000t of oore per year), and thus the few operations that use open pit mining techniques are of a much sma ller scale than for example copper or iron ore mines Currently, open pitting is u sed for example at Los Santos (skarn, Spain).

Mines are either open pit mines or underground operations Open pit mines are most commonly used, 83 percent of copper mines in the US are open pit14 This method is used because a greater amount of ore can be processed and the processes offer more safety and access for mine workers 15 In open pit operations, the fist step is the removal of .
