Assuming a copper content of 2 grams per liter in the feed liquor the acid consumption/ton of copper treated is 0. 75 tons i.e. a cost of approximately $29.00 per ton copper. A high proportion of the acid in the bleed can be re-used in the leaching operation, reducing the net cost of acid in a typical operation to only $9 to $10 per ton copper.

The environmental damage is an external cost and is not borne by the owner and as such it will not be part of the extraction decision.
