Processing of Nickel Laterite Ores on the Rise

The SX-EW Method. SX-EW, or the Solvent Extraction Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore. This process is often referred to as Leach Solvent Extraction Electrowinning for its employment of a leaching step.
