Stage 1: Crushing and grinding The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. (Courtesy of Rio Tinto.) Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath .

· The first step in this process is crushing and powdering ore in a ball or rod mill. Sulfide Copper Ores . Virtually all sulfidetype copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting. After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with .

A process for abrasively grinding copper comprising (1) cooling the entire copper workpiece to a cryogenic temperature and (2) abrasively grinding the copper workpiece while it is at said cryogenic temperature. The workpiece is preferably immersed in liquid N2 during the abrasive grinding thereby preventing adhesive wear from occurring at relatively high metal removal rates.

copper, iron and silver. In fact most of the silver was recovered from lead ores. To enrich an ore in its valuable minerals it was necessary to crush it into small fragments then pick up the mineral values and discard the valueless minerals. Hence crushing of ores became the first step in beneficiation. In the early years of the schools of mines, teaching of mining and metallurgy, and ...
