Lean 6 Sigma tools in mining

  • 1
    Takt time.
    Represents the frequency (or 'rhythm') at which your process must produce output, in order to meet target.
  • 2
    Control limits.
    Represent how well your process is capable of performing now, when it operates 'normally', and how much variation you can expect.
  • 3
    Out of control points.
    Show the abnormalities in your process, which represent quick opportunities to improve your process and reduce variation.


  •     This is an excellent level of improvement. Now we need to apply these methods to all our processes.

aorist Mine Lean 6 Sigma & Process Management

Improve the 'rhythm' of the processes in your mine and minimise variation to get the results you need.

Having processes that consistently produce what they should, when they should is critical to successfully increasing output and reducing costs in complex and inter-dependent mine processes. Through our years of experience in helping clients manage the rhythm of their processes more effectively and in minimising variation, we can help you increase output, reduce costs, and consistently meet your promises around production targets.
