Choosing mineral flotation collectors from large nanoparticle libraries
A secondary goal was to demonstrate a high throughput strategy for designing nanoparticle flotation collectors. As a first step, herein we focus on two of the properties – colloid stability and hydrophobicity. These are a generic requirement for all mineral flotation operations, whereas mineral affinity is specific to the mineral type.

Effect of Pulp Density on Gold Flotation Recovery
The recovery of free gold and/or gold associated with other sulfide minerals is inherently a slow process relative to other types of sulfide mineral flotation. Thus avoiding any operating condition that inadvertently slows down the rate of flotation, including reagent overdosing, should be avoided if at all possible.
