GCSE CHEMISTRY Extraction of Copper Thermal
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. Bioleaching andОнлайн-запрос

Copper production & environmental impact
The solvent extraction process specifically generates a "sludge," or, as it is known in the copper industry, "crud" or "gunk." Sludge is periodically removed from the system, and centrifuged or otherwise treated to remove the organics. The aqueous solutions and the solids are disposed of and the organics are returned to the solvent extraction circuit for reuse. Depending on the characteristics
