The length of the grinding time had little effect on the flotation behavior of pyrrhotite in both grinding media system while the change in pH value had a great impact on the mineral floatability. For both systems, the stronger the alkalinity of the pulp, the lower the recovery of pyrrhotite and the pulp potential value was reduced with the increase in pulp pH value.

Abstract Mechanical activation of the 2:1 layer lattice aluminosilicate pyrophyllite is investigated, with particular regard to the implications of this process for gold preg-robbing behaviour. Short-term grinding in a high energy laboratory ring mill increases the adsorption of gold by pyrophyllite in an acidic chloride medium, which would be problematic in the operation of a,

Effect of Dry Grinding of Pyrophyllite on the Hydrothermal,The mixed grinding of pyrophyllite and gibbsite enabled us to synthesize zeolite Na-A monophase.
