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 s

ASARCO ? Refining

Scrap copper comes from manufacturers of all sorts of copper and brass products. The copper is melted and cast into anodes and refined just like ‘new’ copper from the mines and smelters. That other 1% is valuable stuff! Refining removes the impurities from the copper, but those impurities are valuable elements like silver; gold; platinum

What Is Copper Smelting? (with pictures)

May 12, 2020The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities. One of the main side effects of the copper smelting process is the production of waste. Refining copper results in three and a half times as much waste as the amount of copper produced.

60 Centuries of Copper: Smelting, Refining and their Products

The final products of smelting and electrolytic refining are cathodes, cast often in the form of copper wirebars and cakes.* The casting are subsequently worked in various ways into wrought forms. Re-melted cathodes may also be cast into ingot bars suitable for the preparation of alloys.

Smelting Wikipedia

OverviewProcessHistoryBase metalsEnvironmental impactsSee alsoBibliography

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a source of carbon, such as coke—or, in earlier times, charcoal.

Copper Smelting Process Furnaces Used, By-Products, and

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal
