May 28, 2019 Mining and Production. Bentonite is usually mined opencast, followed by drying, crushing, grinding or screening. Drying may be on drying pads solar drying and or in rotary dryers. Different bentonites are often blended to achieve desired final specifications and performance.
Mining and processing. Bentonite is a raw material present in many countries and mined in open pit quarries. Bentonite deposits are most often quite large, with lenticular beds, only a few meters deep. Bentonite production process features ore mining, sodium activation if required -, drying, and milling.
The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.

The term Bentonite was first used for a clay found in about 1890 in upper cretaceous tuff near Fort Benton, Montana. The main constituent, which is the determinant factor in the clays properties, is the clay mineral montmorillonite. This in turn, derives its name from a deposit at Montm. The term Bentonite was first used for a clay found in ...

Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit. To quantify recovery is a reasonable idea of the initial ore required to have an economical operation. In this part, a reliable sampling representing the ore is a key aspect.

Bentonite minerals occur as lenses or seams containing up to 50 moisture. They are rocklike in nature and usually extracted by opencast mining quarrying. Natural sodium bentonite as the name suggests occurs with sodium as the predominant exchange cation. The name originates from its discovery near Fort Benton, USA.

Generally, the Bentonite mines are open cast mines andBentonite deposits occurs below an overburden ranging from 1 to 8 meters. The overburden, thus excavated is dug out from the pit using JCB and tractor-trailers. After removing the overburden, the Bentonite layer which is in direct contact with the overburden is also removed and discarded.
