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. Comparing this ‘theoretical’ curve to actual grade recovery will provide insight in to the efficiency of

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

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

This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a “Grade/Recovery Curve”. This is a graph of the recovery of the valuable

The effect of froth depth on air recovery and flotation
01.10.2012· Although high concentrate flowrates are measured, the low concentrate grades show that this is due to the higher recovery of gangue rather than valuable mineral. As froth depth is increased, longer froth residence times allow for more drainage of unattached material, and it would be expected that this would result in lower froth mobility and mineral recovery.

Recovery of high-grade copper from waste printed circuit . The flotation results show that the copper grade of the concentrate first increased and then decreased with the increase of the grinding time while the recovery gradually decreased from 78 7 to 21 7 Concentrate with 79 1 copper grade and 71 5 recovery was obtained when the grinding time was 3
Froth flotation Wikipedia
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. As the curves are shifted in the positive x-direction (to the right) and the

The mineralogical deportment and size of the gangue presented in these two graphs suggest that the non-sulphide gangue is being recovered to the flotation concentrate by the mechanism of entrainment. The entrainment process is size dependant, with more recovery by entrainment occurring at finer particle sizes due to their lower settling
