How are clays processed?

Clays usually are transported by truck from the mine to the processing plants, many of whichare located at or near the mine. For most applications, clays are processed by mechanical methods,such as crushing, grinding, and screening, that do not appreciably alter the chemical or mineralogicalproperties of the material.

How are interlayer cations formed on hydrated clay mineral surfaces?

formed on hydrated clay mineral surfaces, particularly those in the interlayer region of swelling 2:1 layer type clay minerals. One emerging trend is that the coordination of interlayer cations with water molecules and clay mineral surface oxygens is governed largely by cation size and charge, similarly to a

What are the primary pollutants in clay processing operations?

The primary pollutants of concern in clay processing operations are particulate matter (PM)and PM less than 10 micrometers (PM-10). Particulate matter is emitted from all dry mechanicalprocesses, such as crushing, screening, grinding, and materials handling and transfer operations.

What is the role of cation adsorption complexes in clay mineral surface geochemistry?

Their role in clay mineral surface geochemistry ranges from critical to subordinate as the layer type shifts from 1:1 to 2:1 (9, 11, 12). Cation adsorption complexes can be classified as either inner-sphere or outer-sphere (3). An inner-sphere surface
