What is a theoretical grade

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 influence of microwave pre

After flotation, each concentrate was pressure filtered and dried overnight at a , seen that the increasing power and treatment time both improve the grade and recovery achieved, with the best result being that achieved at 12 kW for 05 s When considering the initial recovery, for a given flotation time of 1 min, recovery increases with both ....
