Abstract:From the perspective of pulp rheology, this paper investigates the trends of pulp rheology and mineral flotation rate in different carbonate and sulfate concentrations by measuring the rheology and related flotation tests. The results show that carbonate and sulfate can significantly reduce the apparent viscosity and yield stress of the pulp with the increase of concentration, and have a dispersing effect on the mineral particles. At the same time, the addition of carbonate and sulfate can promote the flotation recovery of chalcopyrite and serpentine.However, it mainly achieves the effect of relatively suppressing serpentine by accelerating the flotation rate of chalcopyrite and reducing the MgO content in the concentrate. There is a negative correlation between serpentine flotation rate and pulp viscosity.
