Copper metal ore

Copper ores are mined widely, most notably in Chile, Peru, China and the United States but also in parts of central Africa and in Mexico and Indonesia; unusually the metal is also found in its pure form, which in part accounts for the antiquity of its use. Copper has high thermal and electrical conductivities and is very widely used in electric cabling, in electrical motors and in printed circuit boards

    Photograph credit: USGS. (Public domain.) 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 cathode

    Pyrite and chalcopyrite, both sulfide minerals, are the primary copper ore minerals, but chrysocolla (copper oxide/hydroxide) and malachite (copper carbonate) are found and mined from oxidized ore zones. Although copper minerals are by far the most important ore minerals, the mine also produces lesser amounts of sphalerite (zinc ore), galena (lead ore), and molybdenite (molybdenum ore)

    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

    The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts

    Copper is an unreactive metal, it reacts only slowly with the atmosphere. This means that huge lumps of copper metal are found buried in the ground as nuggets. This is called native copper. The largest nugget of native copper ever found came from Minnesota, USA and weighed over 400 tonnes. Native copper isn’t mined because there is so little

    The patina that forms on copper and bronze is copper carbonate. The majority of metal ores are oxides, carbonates, or sulfides (the combination of metal with sulfur.) In extreme heat and relatively fresh air, i.e. in a kiln, they all remain or turn into an oxide. In the case of carbonates, the heat drives off the carbon dioxide and substitutes

    Jan 25, 2020 The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels
