Project Details


The Sulfolix project involves expanding the El Abra porphyry copper open-pit mine and processing facility. The objective is to develop a large sulfide deposit and extend the mine life by over 10 years to 2023. The project, with an investment of US$725mn for, includes constructing permanent leach pads to treat sulfide ore and replacing the current dynamic leach pads used to process oxide ores. The new leaching facilities will have capacity to process 115,000t/d of ore, and the mine's designed production capacity is 225,000t/y of cathodes. The mine will continue using existing facilities for crushing and SX/EW processing, and will require 550 workers during the construction phase. Sulfolix is run by SCM El Abra.
