Though Edison's inventions in ore concentrating contributed much toward the methods currently used, the only item of immediate value to himself was the titan roller-crusher, which he turned to use on his next project, Portland cement, for which it is still used today. All this happened in the late 90's.

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

The ore is first ground into fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt. Froth Flotation Method: This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in the water.
