Solved: A Froth Flotation Process Is Used To Concentrate C

A froth flotation process is used to concentrate copper ore. It is a twostage process that involves one rougher stage and one cleaner stage. The cleaner tailings return to the rougher flotation. Both stages are nonreactive unit operations that operate at steadystate.
