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 indicates an extremely strong economic incentive for the use of gravity in flotation mills.
