Engineered membrane separation (EMS~(TM)) systems for acid hydrometallurgical solution concentration, separation, and treatment

摘要

HW Process Technologies has successfully developed and commercialized various applications utilizing Engineered Membrane Separation (EMS~(TM)) systems for the processing of acidic copper hydrometallurgical solutions and wastewaters. Copper hydrometallurgical EMS~(TM) applications include water balance control and increased copper concentration in heap and dump copper leach operations, tankhouse bleed stream treatment to separate/recover copper and cobalt from iron, and removal of PLS/Electrolyte suspended solids/colloids to eliminate "crud" formation during copper SX/EW.
