Jun 01, 2015· Drilling mud — a mixture of water and bentonite clay (usually) we use to advance a borehole into the subsurface. When planning a project, drillers normally have some idea about the type of mud and additives they will use, and it usually includes bentonite, soda ash and water. There are many additives for so many different purposes that it can be overwhelming, but these additives are often ...

A bentonite binder composition and method of preparation is disclosed. The binder composition is particularly useful for pelletizing iron ore fines. It is prepared by intimately combining and mixing wet bentonite in a stockpile with soda ash, the moisture in the wet bentonite bringing about reaction to form an improved binder after a suitable aging period.

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 ...
