Method for achieving enhanced copper flotation

May 05, 1992 · In froth flotation, ground ore is typically fed as an aqueous slurry to froth flotation cells. The chemistry of the slurry is adjusted such that certain minerals selectively attach to air bubbles which rise upward through the slurry and are collected in froth near the top of a flotation cell.
