Flotation

The electrolytic flotation has mainly been used for small plants with capacity between 20 and 30 m 3 h −1. In dissolved air flotation, the bubbles are produced by controlling the pressure of water saturated with air. Three main processes of dissolved air flotation include vacuum flotation, microflotation, and pressurized flotation.

Livingston Mill

In the late 1940s and into the 1950s, a new company built a 300-ton (per day) flotation plant and ball mill. They were only active for a few short years, and the mine fell idle. This flotation mill is nearly intact and is the first thing we toured. Overall, the mine was successful; over a half million ounces of silver came out of this mountain.
