Ways of increasing recovery in copper flotation process

May 04, 2021 This study aims to investigate the best route to increase the recovery of oxide-sulfide copper ore. Among various methods, using nanoparticles is more desirable because of their high efficiency. So, ZnO nanoparticles were synthesized and surface modified via anionic sodium dodecyl sulfate (SDS) surfactants. The results showed a recovery increased increase from 27.37 to 38%

    What is a theoretical grade-recovery curve? An example

    Oct 26, 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

    Common Questions About Froth Flotation Process Technology

    Apr 17, 2019 Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation

    Increase Gold recovery in Copper flotation - Froth

    If the gold is combined with the copper than if your current grade is 0.8 g/t (grade), to raise this you need to reduce the overall recovery, and lose copper. If the gold is separate than you need to adjust the scavenger and re-cleaner circuits to get more recovery of the gold by adjusting the reagents. (Note you may lose copper doing this also)
