What is a theoretical graderecovery 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 ...

May 30, 2016 Figures 1 and 2 show how nickel cumulative recovery and grade varied with time during the flotation for the varying dosages of the copper sulphate added to the pulp. The overall consideration shows that at 15 g/ton copper sulphate dosage, nickel recovery improved clearly by a maximum of about 6 % without grade compromise.
