Placer Mining is the extraction of alluvial mineral deposits, either in pits or in river beds. It is usually applied to heavy minerals including gold, other metals and gemstones. Techn iques range from panning, in the ASM sector, to hydraulicking where high-pressure water jets, called monitors, fed by pumps, are used to excavate and transport the material, mixed with water, to a processing plant.

Opencast Mining - an overview | ScienceDirect Topics

Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 ).
