Major Mines & Projects Stibnite Project

Low-antimony mill feed is processed in the gold flotation circuit only, bypassing the antimony circuit. Antimony flotation is designed to remove stibnite (Sb2S3) from the feed stream prior to gold flotation. Reagents are added to activate stibnite and depress the gold-bearing sulfides (pyrite and arsenopyrite) during antimony flotation.
