Copper Smelting Process - Furnaces Used, By

Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a by-product. 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. .

GCSE CHEMISTRY - Extraction of Copper - Thermal .

2017-3-27  Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
