Heavy Mineral Separation | Rock Preparation at ESS

Heavy Mineral Separation. Ze Lab and ESS offer various pieces of equipment and chemicals for heavy mineral separation. Our procedure usually starts with a standard separation with our in-house shaking table; we then use heavy liquids to refine our density extracts. We then further separate heavy minerals according to their magnetic properties.

Froth Flotation Process - Mineral Processing & Metallurgy

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
