The Sepro Leach Reactor is a high yield processing solution designed to drastically improve mineral recovery from gravity concentrate. Combining long-term production value with low operating costs, the SLR is installed after concentration in a circuit to maximize gravity treated ore. Extensive test work of the SLR on site has shown over 99% of the target mineral is recovered through a simple, fully automated process that is easily incorporated into recovery operations. Sepro designs and supplies complete, customizable recovery circuits incorporating leaching, gravity concentration, agglomeration, and electrowinning based on project requirements. Laboratory units are also available for SLR testing which generate reliable data for scale up to commercial operation. Pilot scale machines are also supplied for field test purposes.
