    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

Using today’s compact mining equipment, copper ore is extracted from the mine.After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes.
