The Sepro Leach Reactor is an intensive leach reactor developed to treat the concentrates produced by batch type centrifugal concentrators. By using elevated concentrations of cyanide and dissolved oxygen, the SLR is able to achieve high recoveries when treating high grade concentrates.The simple design is based on reliable technologies that have been used in the mineral processing industry for many years. The standard design consists of a conical bottom holding tank and an agitated leach tank. The system is fully automated and controlled by a local PLC. Custom designs are available to suit the unique needs of each application.
