copper processing | Definition, History, & Facts |

Solvent extraction using organic solvents is of great importance in the purification of leach solutions and in the concentrating of dissolved copper into smaller volumes. Copper from very dilute solutions was formerly recovered by cementation on scrap iron; this produced an intermediate product that was usually returned to a smelter. Modern solvent extraction, on the other hand, has led to some procedures in
