dust in bentonite milling

Bentonite treatment is capable of dust reduction over the long term (2-3 seasons). Normal maintenance blading operations can be used on Bentonite treated areas. Soda ash dispersed Bentonite treatment is estimated to be more than twice as cost effective per percent dust reduction than conventional chloride treatments, with respect to time

    Mar 10, 2021 Problems like acid mine drainage are relatively common and persistent problems facing the mining sector. The groundwater near one coal mine in Nigeria had tested positive for iron concentrations in the ca. 1,300 mg L-1 range of iron, at which levels toxicity is a problem. Using a combined coal fly ash, anthracite and bentonite clay regime, these levels were brought down significantly(13)
