Proprietary Programs and Database

  • Empirical Mill Sizing Program
  • KINCALC®:  Program to calculate flotation kinetics from test data.  This program is commercially available in 2003 and 2007 Microsoft excel versions in Windows XP. To date, Anglo Platinum has purchased a 5 user version and a single user version has been purchased by Barrick, Canada and Magotteaux, Australia, (more details of KinCalc® may be found in the “Downloads” section),
  • EMC has recently purchased Mathematica (www.Wolfram.com) which is a very flexible and mathematically powerful application for computations.  In EMC’s view, it has a simpler and more user friendly operating system than Microsoft. Currently KINCALC® is being reprogrammed into Mathematica. Zimplats (Zimbabwe) have purchased a single-user copy of KinCalc in Mathematica.
  • SUPASIM®  Flotation simulation program - customised by Dave Wiseman Pty Ltd to run in LIMN.  The program is used to design and optimise production scale plant.  Pilot scale test campaigns have been designed and simulated prior to testing so that the best circuit(s) are run – thus saving time and money.  The Supasim program is currently not for commercial sale (more details of Supasim may be found in the “Downloads”section),
  • Milling database of some 220 milling situations of all types and configurations from 0.31mØ pilot to 12.2mØ operating plant scale covering PGMs, BMS, Copper, Nickel, Iron Ore and Talc ores including slag, tailings and matte,
  • Flotation database and simulations of some 60+ operating plants and over 3,500 rate and batch/locked cycle tests covering PGMs, BMS, Copper, Nickel, Tin, Rare Earths, Talc and Phosphate ores including slag, tailings and matte.

Accuracy of SUPASIM® Flotation Simulation Program

Plant simulations use two-component Kelsall flotation kinetics generated from laboratory scale rate tests.  Accuracy is best illustrated by the graph below which compares plant and simulated recovery.  Circuits simulated range from simple rougher-cleaner-recleaner to more complex two stage mill/float (MF2) producing three final concentrates with ultrafine grinding of second stage cleaner tailings.
