Seawater Mining at Minera Esperanza by Boris Leal Martinez is a document available to read on EtoBox.
Minera Esperanza mine uses sea water for its operations, obtaining water from the ocean via a 145km pipeline. Using sea water presented challenges for the flotation and sedimentation processes due to higher salt concentrations. However, the mine developed innovations using metabisulfite instead of lime in flotation, and optimized sedimentation. As a result, Esperanza is able to achieve high copper, gold, and molybdenum recoveries and commercial concentrate grades using sea water despite the location
