HIGH YIELD TYPE BENTONITE

BENTONITE FOR MINING BOREHOLES

It is used to increase viscosity and to control filtering; it reinforces the bore walls and suspends cuttings.

It increases drilling mud claning ability.

It provides stability to minimize risk of collapse in unstable formations.

It approximately doubles the yield of common bentonites.

It is easy to mix in order to obtain a high viscosity mud.
