  • Materials handling issues require special attention when heap leaching
  • Crushing can be highly problematic with screen blinding and low through with cone crushers
  • Agglomeration with cement is mandatory when processing WSO for percolation and heap stability
  • The amount of cement is that required to achieve minimum percolation not to make hard marbles
  • Gold recovery can be very high with WSO
  • Column testing is mandatory to confirm leach kinetics, percolation, slumping and reagent costs
