Approximately 60% of the activated carbon manufactured for liquid phase applications is used in powdered form. Regeneration of the used granule form of activated carbons can be achieved by washing with organic solvents, mineral acids, caustic soda, steam, or .
Calcined Bauxite Calcined Bauxite Guyanan. Pigmented Bauxite, which is produced inhouse and is available in the main safety colours, is used to give an element of high visibility to antislip and antiskid decorative surfaces. It is used extensively in warehouses, loading areas, high visibility pedestrian and vehicular safety areas.
Calcined bauxite is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 1800 degree Celsius. In this calcination process the high refractory mineral phases corundum and mullite are formed. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance.

May 03, 1977· Hence, use of aluminum oxide or bauxite in amount in excess of about 2% by weight, based on the weight of the trona, is desirably avoided. Calcination of the trona is ordinarily conducted in direct fired rotary furnaces or in indirectly heated rotary furnaces, and both types of furnaces are eminently suitable for practice of the method of the present invention.

Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gasfired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 °C, to remove moisture, drive off volatile matters, increase the density of .
The wet limetreated bauxite may be dried and calcined at temperatures from about 250 to 500 C. High temperature calcination exceeding 500 C. renders the alumina less soluble, so that the desired temperature is about 450 to 500 C. The resulting calcine is then subjected to the usual caustic digestion.

Zadie Neufville. KINGSTON, Apr 6 2001 (IPS) A land use and forest cover study to determine the rate of deforestation and to kickstart a forestry conservation programme here has revealed that bauxite mining is the single largest contributor to deforestation in Jamaica. In 50 years of operation the industry has stripped 5,099 hectares land of trees, including some 3,218 hectares of forest.
