Jul 08, 2019 · Solvent extraction Once PLS is leached, it is sent to a solvent extraction plant to remove the copper. The PLS is mixed with an organic solvent that binds to the copper and chemically separates the copper from the rest of the liquid. Then, the copper-bearing liquid is combined with another acid to precipitate the copper from the organic material

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
