Predicting Flotation Recovery

Jan 24, 2019  Predicting Flotation Recovery. Unfortunately, many milling engineers rely rather heavily on percent recovery as a strict measure of a concentrator’s relative performance. The fallacy of this reasoning is not difficult to see since, by definition, percent recovery is a function of feed assay, tails, and concentrate grade.

1 Froth Flotation – Fundamental Principles

1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a “Grade/Recovery Curve”. This is a graph of the recovery of the valuable metal achieved

Advantages Of Using Gravity Concentration For Gold Recovery

While froth flotation and cyanide leaching both play major roles in gold recovery, the benefits of using gravity concentrators cannot be understated. As a low-cost addition to any circuit, it helps optimize the recovery process and mitigates processing risks due to ore variability. Here are just a few advantages of adding gravity concentrators ...

Enhanced Gravity Concentration for Precious Metal Recovery

1) Elevated Grade. Precious metals become concentrated within grinding circuits. In extreme cases the ratio of grade between cyclone underflow and overflow can be >50. Placing a concentrator on cyclone underflow maximizes the precious metal units that the enhanced gravity concentration equipment sees per unit of feed. For a long time it has ...

Good level control on flotation concentrators - September ...

The purpose of a flotation concentrator is to recover the most amount of valuable mineral to the concentrate, whilst at the same time keeping the quantity of concentrate down to a minimum, which enables the highest recovery of valuable mineral at the desired grade to be achieved. This is known as the ‘grade/recovery curve’ for the concentrator.
