Bentonite Mining Open Pits
OpenPit Mining Methods
· Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the ...

Mining by openpit method will finish by 2015 [6, 7]. Diavik diamond mine which uses openpit method is expected to cease by 2012 and it will become totally underground thereafter [8]. Kanowna Belle gold mine in Australia is the other mine is another example where the transition to underground mining was done by early 1995 [9].

Bentonite
· Bentonite is a clay consisting mainly of smectite minerals, commonly formed by decomposition of volcanic ash or tuff, or sometimes from other igneous or sedimentary rocks. Bentonite is a very plastic clay that shrinks (or swells) markedly in response to the removal (or addition) of water. There are three main types of bentonite:
PHASES OF A MINING PROJECT
Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
