More specifically, the improved process is a method for recovery of metal values by froth flotation from metallic sulfide mineral ores comprising copper and molybdenum, including the steps of a forming an aqueous mineral pulp from the ore b subjecting the pulp to rougher flotation to provide a scavenger feed and a rougher concentrate.
The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons 1 in most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.
