Trona is a sodium carbonate compound that is processed into soda ash or bicarbonate of soda, or baking soda, as it is commonly known. Wyoming has the world''s largest deposit of trona, supplying about 90% of the nation''s soda ash. This mineral is Wyoming''s top export and is shipped to markets around the globe.
Feb 08, 2020· It is usually combined with soda ash to be reactivated and used. Bentonites usually contain some impurities such as quartz and gypsum and may require filtering and purifying before use as a building material. One characteristic of bentonite clay, particularly the sodium type, is its ability to expand when water is added.
Method of converting calcium bentonite to sodium bentonite that is suitable for use as drilling mud or a cement additive. After the addition of a calcium bentonite sample to a prepared soda ash solution at predetermined soda ash/bentonite weight ratios, the bentonite suspension is continuously heated and stirred for up to 24 h. The heating and stirring are crucial towards enhancing the sodium ...
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). Bentonite is subsequently dried (air and/or forced drying) to reach a moisture content of approximately 15%.

Soda Ash is the common name for Sodium Carbonate Na 2 CO 3. It is used primarily to remove calcium from make up water and to treat calcium contamination, primarily from drilling anhydrite. Over treatment of soda ash may result in excess carbonate, detrimental to bentonite drilling fluids.
Soda ash can often be purchased in the detergent section of stores as washing soda, sal soda, or natron. (Sodium bicarbonate, called baking soda, is not the same thing). Soda ash dissolved in water before adding bentonite will improve the bentonite properties by adjusting the pH and the ''''hardness'''' of the water to the ideal range for ...
