201722· These can be compared with figures given recently by McGarr et al. Assuming total labor costs of about $24 per ton of copper produced, the overall operating costs of solvent extraction plus electrowinning can be as low as $72 per ton of copper. For cement copper production freight and smelting charges alone usually exceed this figure.

Fundamentally new routes to decouple metal production from greenhouse gases at an affordable cost are required for all major metals. Electrowinning, in particular if it can be directly applied to the metal-containing compound from the ore, is an especially relevant option, providing sustainable and cost-effective power is available.
