A copper flotation circuit (shown below) operates with two stages (Rougher-Scavenger)

A copper flotation circuit (shown below) operates with two stages (Rougher-Scavenger) of flotation cleaning. The Cu assays of all streams are listed below. f=0.8%, cl=8.5%, c2=2.5%, tl=0.1%, t2=0.019% Assume a flotation feed rate of 1000 tph, determine the followings: a. Overall grade of flotation concentrate b. Copper recovery and enrichment ratio obtained from the overall circuit f Rougher Scavenger > t1 t2 c1 c2
