The ore is Copper Sulfides with liberation size of 130 um, Pyrite of 100um and Magnetite of 160. since magnetite is the coarsest, can we place the magnetic separator before flotation. Our ball mill is set to produce a P80 of 150 um in the cyclone ove...

Usually one would go for float first and then followed by magseps. Put it magseps prior to float might compromise your C...

Dear All  I need to transfer some phosphate froth concentrate (coming from flotation cells) and feed a dewatering hydrocyclone. What should be my average solid concentration for a correct pumping ? I consider 21% solid (weight basis). Do I need to ...

A slurry pump is best. Froth (air) does not pump.
