Bentonite - Wikipedia
One problem with adding bentonite is that it typically contains minerals that affect the color of the mix. Ceramic glazes often contain bentonite. The bentonite is added to slow or prevent the settling of the glazes. It can also improve the consistency of appli ion of glazes on porous biscuit-fired ware. Once a certain amount of glaze water

The beneficiation of lithium minerals from hard rock ores: A
In many lithium ore beneficiation plants it is a common practice to de-slime the ore prior to flotation. De-sprm is typically carried out to remove the −20 µm size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit Bale and May 1989 . As is the case in many operations de-sprm is
Effect of desprm on the magnetic separation of low-grade
In the present investigation magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to contain 22.4% Mn and 35.9% SiO2 with a manganese-to-iron mass ratio Mn:Fe ratio of 1.6. This ore was characterized in detail using different techniques including quantitative evaluation of minerals
