passes through electrowinning cells where the gold is deposited on to cathodes of knitted stainless steel wool. The loaded cathodes are removed from the electrowinning cells and manually washed using high-pressure water jets to dislodge a gold sludge. This is filtered, after which the filter cake is smelted and cast into impure* gold bars. These bars are sent to a refinery, generally at a ...

Silver | Gekko

The cell’s high current density and unique ‘drop site’ design, for collecting silver solids, ensures that electrowinning is efficient and continues uninterrupted. Pregnant solution recovery of lower grade silver solutions is achieved by resin-based, carbon-in-solution or zinc precipitation (Merril Crowe) processes.
