Silver Gold Recovery Flotation Process

The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class ...

First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.

GRAVITY RECOVERY OF GOLD FROM WITHIN GRINDING CIRCUITS

According to Dr. André Laplante Laplante, 2005 the benefit for every 10% of recovery by gravity usually falls in the range of 0.5-5% of additional overall gold recovery. This rule of thumb is based on a large database of mills from around the world and indi es an extremely strong economic incentive for the use of gravity in flotation mills.
