  • Froth Flotation Principles

    Feb 26, 2017  Lead-Zinc-Gold-Silver Flotation: This Colorado mill, treating a complex lead-zinc ore carrying gold and silver values, uses a Mineral Jig and a “Sub-A” Unit Cell in the closed grinding circuit. The jig recovers coarse and fine heavy minerals (as soon as free) which are difficult to float due to size and specific gravity.
