Surface Coal Mining and Reclamation. Surface coal mining involves disturbing overlying rock layers (overburden) to expose and extract coal reserves using the area mining method wherein the overburden above the uppermost coal seam and the innerburden between the lower coal seams are removed in parallel strips (pits) across the coalfield until the area is mined.

The Mining ProcessWaihi Gold

A slurry of ground ore water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93 of the gold and 70 of the silver.
