copper ore production

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 milling of copper ores …

Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

RTB Bor, Serbia: Copper ore production up, processing costs down Together with , the Serbian RTB Bor mine renewed the processing plant at its largest site, Veliki Krivelj. The result was a higher throughput and better recoveries with less energy consumption per ton of processed copper.

The last reported copper production using ore from within the state was eighteen tons in 1952, valued at $8,712; it mostly used ore from the old Hazel Mine in Culberson County. During the mid-1950s most of the Texas copper mines were inoperative.

The remainder of primary production comes from ores in which copper is present as silicates, sulfates, carbonates and oxides, which have been formed by the weathering and oxidation of sulfide minerals. About 30% of all copper production is recovered from secondary and scrap materials which are recycled.
