Flotation Circuit: Concentrate Grade and Recovery

2013-6-19  Flotation Circuit: Concentrate Grade and Recovery. The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for a given feed ore.

Concentrate Grade an overview ScienceDirect Topics

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

What is a theoretical grade-recovery curve? An example

2009-10-26  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. The theoretical grade-recovery can be readily used to quickly identify potential recovery

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

Case of Study for a PbS flotation circuit. I have worked on a PbS lead ore (2.3% Pb feed), and I got a 50% grade and 60% recovery by applying a flotation circuit (see figure below). Then I wanted to increase both the grade and recovery. After several analyses, I concluded that it is the liberation size that would have more effect.
