Depression of Lead-activated Sphalerite by Sodium Hydrogen Phosphate for Red Dog Mine Operation
DownloadSpring 2019
The inadvertent activation of sphalerite by lead ions have been noticed and studied for decades. In this study, flotation behavior of sphalerite upon lead activation was studied. Sodium hydrogen phosphate was applied as a main depressant to test its effect on improving Pb-Zn selectivity. Surface...

Abstract In this study a complete solution methodology is developed for the simulation of hydrocyclones. A commercial software package, Ansys 12 Fluid Dynamics (Fluent), is used to solve the governing conservation equations. Turbulence is modelled using the large eddy simulation, and the...

The extraction of bitumen from oil sands using non-aqueous extraction (NAE) techniques has the potential to replace currently used water-based extraction techniques. High bitumen recovery rates, lower freshwater requirements, and elimination of afterward tailing ponds are all advantages of...
