Froth flotation - Wikipedia

Grade-recovery curves. Grade-recovery curves are useful tools in weighing the trade-off of producing a high grade of concentrate while maintaining as low of a recovery rate as possible, two important aspects of froth flotation. These curves are developed empirically based on the individual froth flotation process of a particular plant.

Flotation - Metallurgist & Mineral Processing Engineer

This is an overview of setting up and conducting a flotation rate test. The test is a means of determining the flotation characteristics of an ore. It is conducted in a laboratory scale cell usually with a volume of two point five litres. The intention is to generate relationships of cumulative recovery, mass pull and grade versus time and use these to evaluate the floatability of metal ...

What is a theoretical grade-recovery curve? An example.

The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process.

Flotation - ScienceDirect

The scavenger section of the flotation circuit is given higher reagent dosages and long flotation time to float as much valuable mineral as possible and maximise recovery. On the other hand, the cleaner stage experiences milder flotation conditions of lower pulp density and lower reagent concentrations to reduce entrainment in the froth and to ensure only the high-grade particles will float.

Froth flotation circuit design and basic testwork ...

Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed, (directly related to ore grade).
