Copper - A Metal Used Through The Ages. Copper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age.
11-04-2017· 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.

hydrometallurgical process for processing copper sulphide concentrates to metal. The basic concept of this process is to allow processing of concentrates on site at the mine, to minimize downstream costs, including freight on concentrate. Although it has outstanding environmental features, the CESL Process also has to be competitive with the existing smelting industry, which has offered very attractive terms to
The main ingredient in the production of steel is iron ore mined from Earth. Over 2,000 million tons of iron ore is mined mined a year - about 95 percent is used by the steel industry. Iron ore is the world's third most produced commodity by volume - after crude oil and coal - and the second most traded commodity - only beaten by crude oil.

According to Gorai et al. (2003), about 2,2 tons of copper slag is generated for every ton of copper production. Approximately 24,6 million tons of copper slag is generated each year from world copper production (Gorai et al., 2003). It is usually disposed in uncovered dumps in the vicinity of a copper …
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
