Recovery Of Pyrite From Copper Tailings By Flotation. Sep 01, 2019nbsp018332considering that at 10 min of flotation the recovery is greater than 90 and that a longer flotation time decreases the pyrite grade in the concentrate this time will be defined as the optimum time for the cleaner stage. the cleaner concentrate will be fed to a recleaner stage and the cleaner tailing with a 10 pyrite

grade-recovery data scatters around a common hyperbola. This can be used to gauge the validity of the assumptions made. Normalized cumulative mass pull is determined from the fitted values of the maximum recovery and maximum grade. This may serve as an alternative performance indicator of the floatation row. BI0543

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

Flotation tests were carried out aiming at the maximization of carbon grade and recovery in the concentrate, while minimizing silicon content. The effect of pH, collector, and sodium silicate (depressant) dosage was investigated on two feeds of different granulometry (− 90 μm, 90–420 μm) and optimum conditions were determined. For pH 8 and kerosene dose of 500 g/t, carbon grade and

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.

When you try to raise the grade, you practically trying to recover valuable minerals more selectively. there are two ways; either you minimize the concentrate mass, or you add cleaning steps for concentrating the concentrate. In the first case, you can not recover many valuable minerals, and in the second one, you will losing valuables at each cleaning step. So, your recovery is down.
