The Sepro Leach Reactor (SLR) is an advanced leaching system for leaching precious metal concentrates generated from gravity concentration circuits; this includes gold leaching. Extensive test work of the Sepro Leach Reactor on-site has shown over 99% of the target mineral can be recovered through a simple, fully automated process that is easily incorporated into gold and silver recovery operations.  Not only does the SLR have low operating costs, it also recovers more gold than conventional physical separation methods.

Laboratory units are also available for agitated leach reactor testing which generate reliable data for scale up to commercial operation. Pilot scale machines are also supplied for field test purposes.
