palygorskite clay processing

Palygorskite Wikipedia

Two companies are involved in the industrial extraction and processing of gellant-grade attapulgite clay within the same Attapulgus deposit: Active Minerals International, LLC, and BASF Corp. In 2008, BASF acquired the assets of Zemex Attapulgite, leaving only two gellant-grade producers. Active Minerals operates a dedicated factory to produce the patented product Actigel 208 and built a new state-of-the-art production process in early 2009 involving portable plant processing at the mine site.

Kaolin, bentonite and other special clays processing

At Verdés, we have a long experience in the supply and installation of machines for crushing and processing special clays such as bentonite, sepiolite, attapulgite (palygorskite) and kaolin. Special clays are those that are constituted primarily by a single type of mineral, and therefore their properties and behavior depend essentially on the characteristics of that mineral.

Enhanced Viscosity of Aqueous Palygorskite

A certain amount of palygorskite and tap-water was mixed and pressed by a vertical extruder. After that, the palygorskite was collected, dried, and ground. Ultrasound Scattering. 25 g palygorskite and a certain amount of tap-water were added into an 80 mL beaker, stirred, and then loaded onto the platform of an ultrasonic cell crusher.

The clay mineral geochemistry of one palygorskite

There are three types of palygorskite clays : (1) weathered palygorskite clays formed by weathering of the basalts, (2) altered palygorskite clays formed by the alteration of volcanoclastic material, (3) deposited palygorskite clays formed by crystalline deposition in the shallow lake basin. However, the last one is the main type of ore deposit while the others cannot be used because of poor quality. The main constituents of the clays are palygorskite
