    This dust is then mixed with water and reagents in our zinc-lead concentrator's flotation circuit. The reagents help us to separate the valuable mineral content from waste rock. Air is forced through the slurry creating bubbles, which float to the surface and attract and bind to the zinc or lead particles. The glossy, mineral-laden "froth" is then skimmed off the top and dried. What remains
