What is a theoretical grade-recovery curve? An

26/10/2009 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

THEORETICAL Limiting Grade Recovery Curve

07/02/2014 THEORETICAL Limiting Grade Recovery Curve. To generate a limiting grade-recovery curve, three points are shown for each mineral. The left most end point of the curve represents the feed grade of the composite. The middle point of each curve represents the concentrate grade produced when all of the particles bearing target mineral are recovered.

Timed Flotation Test & Cumulative Grade Recovery Curve

22/11/2016 A recovery time curve which exhibits a step change increase in recovery after a time consists of two separate components. This can be caused by stage addition of reagents mid-way which reactivates mineral or by the presence of a second component that is free to float after the first component has been recovered.

A new approach in separation process evaluation

The evaluation of process economics is of great importance in mineral processing, because the grade-recovery relationship is a key factor in determining the best combination of grade and recovery as a point of process economics. However, in mineral processing the aim is to attain the highest financial return per ton (megagram) of a processed ore in the plant. One of the proposed parameters for

14/02/2021 We observe that as \(\mathrm{Cu}\) grade increases, recovery decreases. This is consistent with the typical grade recovery curve. If recovery is 100%, the grade has to be the feed grade to the process because it is so difficult to get every single particle into the concentrate. We can never get 100% recovery, we can only asymptotically approach 100% recovery. Similarly, we cannot
