  • Flotation Circuit: Concentrate Grade and Recovery

    2013-06-19  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.

    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.

  • 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 ...

    The flotation recovery rate: ... Mineral processing theory rate of recovery (%) = concentrate grade * (raw ore grade - grade of tailings) / ( raw ore grade * (grade of raw ore concentrate grade - grade of tailings)) * 100% = amount of metal theory recovery (g) / processing ore metal quantity (g) * 100%. The actual dressing recovery rate (%) = gold concentrate gold ore gold content (g) / (g ...

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

    2009-10-26  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 cleaner concentrate will be fed to a recleaner stage and the cleaner tailing with a 10% pyrite grade will be recirculated to the rougher stage. The pyrite flotation in ...

    The amount of airflow directly affects flotation performance and so has a major impact on the metallurgical recovery and grade of the concentrate. In addition to bubble/particle interaction, air also helps to control the speed at which concentrate is removed from the cell. Increasing the air feed produces more bubbles, leading to a greater probability of bubble/particle interaction, which in ...
