Flotation Time On Concentrate Grade And Recovery

Flotation Circuit: Concentrate Grade and Recovery

Jun 19, 2013 · 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

For example shown here is the recovery time for niobium in a carbonate and sulphur flotation stage. Recovery is rapid and the float reaches a plateau after just three minutes. In this case eight concentrates were collected at half minute intervals up to a total of four minutes.

Flotation - Metallurgist & Mineral Processing Engineer

This is an overview of setting up and conducting a flotation rate test. The test is a means of determining the flotation characteristics of an ore. 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 time and use these to evaluate the floatability of metal ...

1 Froth Flotation – Fundamental Principles

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 metal achieved

What is a theoretical grade-recovery curve? An example.

Oct 26, 2009 · From the example here if we looked at Cu recovery the theoretical grade recovery curve would correspond to figure 5. In this case the maximum grade of Cu is restricted by the host mineral, hence to chalcopyrite the Cu grade cannot exceed 34.63% in the concentrate, even assuming 100% recovery of chalcopyrite.

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.

A study of selective flotation recovery of rare earth ...

Flotation rate test measures flotation performance in terms of mass pull, recovery, and concentrate grade. The variation in recovery of mineral particles over time is characterised as the flotation kinetics of the mineral , . The results obtained are used to describe the flotation performance of a mineral under flotation conditions at a time.
