Longtime MECS partner, SNC-Lavalin, will provide detailed engineering, procurement and construction (EPC) services for the new plants, each of which is expected to produce 2048 tpd of market-grade sulfuric acid. These plants will replace existing facilities which have become environmentally obsolete.

“MECS technology for Chuquicamata will be designed and custom-built to address the site’s specific needs, especially achieving world-class low emissions and high reliability,” says Kirk Schall, Executive Vice President, MECS. “We are delighted that our best-in-class sulfuric acid production technology will help Codelco’s Chuquicamata site realise its short and long-term emissions targets while supporting the sustainable production of the Antofagasta region’s most valuable resources. MECS looks forward to partnering with both Codelco and SNC through start-up and with Codelco throughout the life of the new facilities.”

Construction of the two new plants will begin in 2017 and is expected to be completed the following year.
