Its CLEVR Process offers a cyanide-free gold extraction process that uses sodium hypochlorite with a catalytic amount of sodium hypobromite in acidic conditions to put the gold into solution. Its GlassLock Process is a patented process for the sequestration and stabilization of arsenic often associated with copper, gold, silver or polymetallic deposits.
