We have built Metsim models for the following process flowsheets:

  • Gold ore processing including bacterial leaching and pressure oxidation
  • Lithium extraction and recovery to lithium carbonate
  • Pressure oxidation of sulphides of nickel, molybdenum and copper
  • Rare earths extraction
  • Copper leaching with SXEW
  • Nickel laterite processing by sulphide and hydroxide routes
  • Multiple hearth roasting and calcine leaching of molybdenite
  • Roast leach electrowin zinc refinery with acid plant
  • Sulphur-burning sulphuric acid plant with power generation
  • Vanadium extraction by chloride leaching with hydrochloric acid regeneration by spray roasting and absorption
  • Steam-methane reforming
  • Coal gasification with gas work-up and shift conversion
  • Iron ore beneficiation including crushing, grinding, spirals, cobbers, LIMS, WHIMS and SLon
  • Concentrators for Pb/Zn, copper, gold-bearing pyrite and rock phosphate
  • Synthetic rutile production by the Becher Process
  • Copper smelting by flash furnace or IsaSmelt with slag concentrating, flash converting, electro-refining, slimes de-copperisation, waste heat boilers, gas clean-up and acid plants
  • Anatase processing by hydrochloric acid leaching
  • Power generation utilising gas, coal and HFO including HRSG’s and steam turbines
  • Aluminothermic production of ferromolybdenum
