Froth Flotation Principles
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.
Column Flotation
Basic Idea Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter-current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice, and allows the user to optimize the performance based on the feed …
The future of flotation
Low grades, complex ores and rising energy costs have prompted the development of entirely new flotation vessels, improvements to existing technology, and new thinking about flotation flowsheets. The froth-free flotation vessel comes by way of Eriez Flotation Division, which patented it in 2002 and marketed it under the name HydroFloat.

Unconventional column flotation of low-grade gold fine …
With low gold grades (0.15–0.4 g t − 1 Au) and a poor liberation, this 3pc cell was able to produce a product (12% gold recovery) with the quality of a rougher flotation concentrate (13 g t − 1 Au). These results could not be attained in the conventional column cell operating under similar conditions.
