     · This technology enabled the expansion of copper supply at an affordable price. Despite the great success of conventional flotation it is known and reluctantly accepted that this technology is very poor for extracting target minerals outside of a narrow particle size range. Typically 5 -15 of recoverable copper is lost due to this inefficiency.
