Copper Recovery by Solvent Extraction Techniques
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.
