How Is Platinum Extracted? - Reference
Platinum ore can be obtained through controlled explosions or by advanced mining techniques. Once it has been mined, the platinum is extracted from the ore in the same way. The platinum ore is not pure, so it is first crushed. This produces many tiny particles that can be treated. Air particles then bubble through an aeration tank and adhere to ...

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.
