The article discusses the new technology used by Goldcorp Inc. to improve the treatment of tailings water at Cochenour Wilanour Mine. Results from the pilot test of ACTIFLO technology in removing arsenic, iron and total suspended solids (TSS) showed 97% arsenic removal through the sand-blaster flocculation and clarification process that produced clarified water with arsenic content at 0.023 milligrams per liter (mg/L). It also mentions the process wherein a coagulant is mixed with the water then injected with a polymer and mixed with microsand.
