|Title:||Effect of flotation reagents on the wet grinding of celestite concantrate|
|Series/Report no.:||B22F 9/00, B03D 1/001|
|Abstract:||In this study, the grinding of celestite concentrate in presence of grinding aids, used for celestite ore, flotation has been investigated in a laboratory wet-ball mill as a function of time and concentration of grinding aids. In the experiments, Aero-801, sodium oleate and sodium silicate have been used as grinding aids at the concentrations of 10, 100 and 1000 g/t. While sodium oleate and sodium silicate have beneficial effect in longer grinding times at concentrations of 100 and 1000 g/t, they have adverse effect on grinding at all grinding times at concentration of 10 g/t as evident from particle size. <i>d</i><sub>80</sub> values of ground products are coarser than that without grinding aid. Aero-801 is the best among the grinding aids tested for the concentrations studied. Considering the fineness of the ground products desired, 100 g/t concentration of Aero-801 appears to be proper for grinding of celestite concentrate.|
