Taconite (IPA: [''tækənaɪt]) is a variety of iron formation, an ironbearing (over 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik ...
The calcium bentonite clays have a high capacity to bind metal ions dissolved in solution. This adsorption, the binding of chemicals to bentonite clay surfaces, is a rapid process and the binding is strong. Once these metals are bound to the bentonite clay they can be rapidly separated from water by removing the bentonite clay.
logical occurrence, mining/processing technology, and uses. They are finegrained minerals of secondary origin and are composed of an alumina silicate structure with additional iron, alkalis, and alkaline earth elements. Clay minerals are classified into two broad groups: specialty clays, which include attapulgite, bentonite, Fuller''s earth,

Mining and processing Bentonite production process features ore mining, sodium activation – if required, drying, and milling Sodium activation is performed to convert calcium bentonite to sodium bentonite, in which calcium ions are exchanged for sodium carbonate Through drying, bentonite natural moisture content of about 2535% is reduced
Cowboy Mining Company (a division of PDSCo, Inc.) is a privately held bentonite mining, processing and packaging operation located in Southwest Texas near Big Bend National Park. We have been surfacemining premium quality sodium bentonite since 1996 and serving customers around the world.
Bentonite deposits are normally exploited by quarrying. Extracted bentonite is distinctly solid, even with a moisture content of approximately 30%. The material is initially crushed and, if necessary, activated with the addition of soda ash (Na2CO3).
Nov 08, 2011· The damage that strip mining does to the land, the cost of fuel to transport the mined bentonite to the drying facility and the use of petroleum products to dry the material make the production of clump litter ridiculously detrimental to the environment. Add to that the fact that used clay litter is not biodegradable and only adds to landfills.
The bentonite which is bare during this process can be as little as 1 1/2 feet or as much as 10 feet thick. This is the material which is mined and processed. Many bentonite manufactures prefer to "field dry" the exposed bentonite prior to hauling it to the processing plants.
