Copper extraction Wikipedia

OverviewConcentration (beneficiation)HistoryRoastingRefiningConcentrate and copper marketingSee alsoBibliography

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals being less than 2% of the total volume of the ore rock. Thus, all mining operations, the ore must usually be beneficiated (concentrated). The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of

Iron ore Wikipedia

OverviewSmeltingSourcesMine tailingsExtractionProduction and consumptionAbundance by countrySee also

Iron ores consist of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond, at high temperatures. Thus, the iron o

Copper extraction Wikipedia

Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. [9] The smelters were initially located near the mines to minimize the cost of transport. This avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the copper-containing minerals.
