Copper extraction Wikipedia

OverviewSulfide smeltingHistoryConcentrationFroth flotationHydrometallurgical extractionConcentrate and copper marketingSee also

Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters

Copper Concentrates Cargo Handbook the world's largest

DescriptionApplicationShipment / StorageRisk FactorsCopper extraction techniques refers to the methods for obtaining copper from its ores. This conversion consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.As in all mining operations, the ore must usually be beneficiated (concentrated). To do this, the ore is crushed then it must be roasted to convert sulfides to oxides, which are smelted to produce...

From Ore to Finished Product 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.

Metal Production from Concentrates Aurubis

Aurubis imports most of the copper concentrates directly from copper mines in different countries. Copper ore is primarily mined in Central and South America, the US and Canada, as well as Africa, Asia, Australia and to a lesser degree in Europe. Copper ores contain about 0.5-4 % copper and are already processed into a concentrate in the mine.

Copper Concentrate Enrichment Process

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.
