Abstract
A mineral separation process includes wet-grinding the ore to liberation of minerals, oxidizing the slurry using air, hydrogen peroxide or other oxidants and floating the valuable minerals at a pH between about 9.0 and 10.0 with a xanthate as collector, and a combination of a polyamine and a sulfur containing species as depressants for arsenide minerals. This depressant suite effectively depresses the flotation of arsenide minerals with no effect on the flotation of the valuable minerals.
