Mining and processing Bentonite
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 reducedThe main consumers for such bentonite are ore mining and processing enterprises using Natural Sodium versus Activated Calcium Bentonite in Geosynthetic bentonite using a sodium activation process (also known as beneficiation or peptization) 9 Dry mixing Ca or Mgbentonite with excess sodium carbonate (soda Bentonite Bentonite how to do soda activation in bentonite Solution for ore The effect of inorganic additives on bentonite dispersions have been investigated in a number of studies The activation with 2 –4% soda is traditionally used to process lower quality bentonites in the industry Lebedenko and Plee (1988) observed that the Na+content was the most significant parameter enhancing the rheological propertiesActivation of (Na, Ca)bentonites with soda and MgO and
