Flotation Circuit: Concentrate Grade and Recovery - MinAssist
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.
Timed Flotation Test & Cumulative Grade Recovery Curve
Apart from conducting a rate test in the correct manner, it’s important to collect the right number of concentrates and at the right times; doing this will ensure that the data you generate maximizes your analysis of flotation response. To properly define the relationship between recovery and time, you need a minimum of four concentrates and four data points on the graph. The timing of these ...
Recovery of pyrite from copper tailings by flotation ...
Sep 01, 2019 · Considering 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 will be ...

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.
Designing flotation circuits for high fines recovery ...
May 01, 2006 · Between them, these operations produce around 1 Mt/y of concentrates by flotation of particles mostly finer than 10 μm, at over 80% recovery. In fact, the best flotation recovery is in the “slimes”. At MRM, 96% of the individual particles recovered are finer than 2.5 μm.
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. The theoretical grade-recovery can be readily used to quickly identify potential recovery ...
