A third set of tests were completed to determine if residual silver and gold recovery using cyanide would be improved if the rocks were first leached using the Rock Kleen, then re-leached using cyanide. Unoptimized test results indicate that recoveries could be improved to the point that up to 90 percent of the residual silver and gold could be recovered. The cumulative results of all the Rock Kleen testing performed to date indicate that the Rock Kleen technology has a high probability to be technically and economically successful for processing silver/gold mine tailings..........Here! They are talking about tailing. Rock Kleen first, then re-lesching using cyanide. Then (maybe?) finish with Rock Kleen to neutralize the cyanide ???? In past PR they talked about Rock Kleen as a bolt on for leaching virgin ore. (Maybe) the same??? Rock Keen first, then cyanide, then finish with Rock Kleen to neutralize the cyanide? Either_ Or, If this could be improved to the point that up to 90 percent of residual silver and gold could be recovered that would be huge I think they need to clear this up a little.
