Chilean state-owned copper miner Codelco has presented an EIA for a US$496,300 project to take advantage of the sulfuric acid flow of the Potrerillos smelter in order to sell acid on the market, according to the EIA report.
The company added it could also utilize the acid from Potrerillos, at the Salvador division, for internal company use.
Sulfuric acid, which is required in some forms of copper processing, has risen greatly in price during recent years along with the red metal price boom.
According to Chile's state copper commission Cochilco, sulfuric acid in this year's second quarter rose to as much as US$360/t and averaged US$160/t in the period, while in prior years acid was worth a fraction of that.
The Salvador division in northern region III is Codelco's smallest branch, responsible for 25,000t of the company's total production of 675,000t in H1.
