The open pit method is often the easiest and the most inexpensive form of mining. Bauxite mining, which commenced in 1916 in Linden, Guyana, has left many abandoned pits upon closure of mining activities; subsequently pit lakes have been formed. Globally, Acid Mine Drainage (AMD) is a common water quality problem for pit lakes.

Improved grade control in open pit mines: Mining …
Grade control in hard-rock open pit mining is the process of determining the destination for the mined material. Numerical studies are undertaken to show how grade control can be improved, that is, less ore sent to the waste dump and less waste sent to the mill. The improvements in four aspects of grade control are proposed: (1) the grade ...

Grade Control
In some mining operations, one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation, this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical types.
