Chapter 7 Energy Use in the Copper Industry

In the traditional view, supergene ore and gangue minerals are the products of reactions between hypogene sulfide minerals and descending, acidic meteoric waters; these processes take place at or near the ground surface in subaerial environments (Guilbert and Park, 1986). In VMS deposits, copper and other metals are mobilized from primary massive

ORE MATERIALS: PRIMARY AND SECONDARY …

Chalcocite has a higher copper content than chalcopyrite and grades of 5 to 10% copper in a laterally continuous horizontal beds are not uncommon. This secondary enrichment may kick start the production of an otherwise mediocre porphyry deposit. Following erosion many porphyries are covered by sediments are younger volcanics.

A Look at the Largest Copper Smelters

A physicochemical model based upon the continuity equation for oxygen in spherical coordinates was developed by Bartlett and examined for leaching of copper sulfide ores. A reaction zone model introduced by Braun et al has been successfully applied to primary copper sulfide ores and more recently to secondary copper sulfides.

Copper - British Geological Survey

Copper is usually found in nature in association with sulfur. 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 …

Copper Toxicity - Copper Toxicity

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

situ leaching of copper ores; from an environmen-tal point of view, this is a questionable produc-tion route. Several different processes can be used for copper production. The traditional process is based on roasting, smelting in reverbatory fur-naces (or electric furnaces for more complex ores), producing matte (copper-iron sulfide), and con-
