The electrolyte produced in the elution process will be transferred to an electrowinning cell equipped with stainless steel mesh cathodes. The circuit will comprise a pre-leach tank and six CIL tanks. calculations. potable water and gland water. operating in closed circuit with a cyclone cluster. after which it will be pumped to the tailings dam.
