  • Install new Warman pumps 300LF on primary flotation concentrate and cleaner flotation feed hoppers to increase pumping capacity.
  • Replace pyrite thickener feed launder with large diameter pipe to increase volumetric capacity.
  • Replace TPP thickener feed drop box with larger drop box to prevent overflows.
  • Install Outotec Flow boosters to primary and rougher flotation cells.
  • Install Sonartrak flowmeters on primary flotation concentrate and cleaner flotation feed pumps.
  • Trial of Cytec defoamer to control spillage from primary flotation concentrate and cleaner flotation feed hoppers by decreasing froth factor and increasing pump efficiency.
