Lean 6 Sigma Kaizen tools in mining

  • 1
    Kaizen crew.
    The members of your team who will work in the Kaizen event to solve throughput, cost, productivity or defect reduction issues.
  • 2
    Kaizen event.
    Typically a 3 day full-time event, focused on solving a specific issue, during which 80% - 90% of the changes identified to address the issue will be expected to be implemented.
  • 3
    Fishbone diagram.
    The diagram produced by the Kaizen crew during the Kaizen event, which shows the most likely causes of the issue being addressed.


  •     This group approach to problem-solving is extremely powerful. We can harness everyone's brain power, and we all own the improvements, which leads to better sustainability.
    D.B. Plant Engineer
  •     We have solved something here that's been dogging us for years. An excellent approach.
    E.L. Plant Supervisor

aorist Lean 6 Sigma mining Kaizen

Quickly solve problems in your mine to increase output and reduce cost.

Having processes that are largely problem-free is critical to consistent production and successfully increasing output and reducing costs in complex and inter-dependent mine processes. Through our years of experience in helping clients apply Kaizen to rapidly address process problems, we can help you solve problems quickly, and so increase output, reduce costs, and consistently meet your promises around production targets.

Lean 6 Sigma mining Kaizen case study - reducing lime consumption

  • reduction of excessive lime consumption in mining plant in lean 6 sigma improvement project Problem
    Excessive lime consumption to maintain a stable pH value.
  • 1. We graphed the results
    So we could understand performance, and if the problem was systemic.
  • 2. We built the 'fishbone'
    So we could identify the most likely causes of excess consumption.
  • 3. We made some changes
    And tested them quickly to confirm they were likely to work.
  • 4. We implemented and measured
    To ensure the changes we made were effective and sustainable.
  • reduction of excessive lime consumption of over $780,000 p.a. in mining plant in lean 6 sigma improvement project Result
    Lime consumption reduced by $15,000 per week (over $780,000 per annum saving) and pH values remained stable and correct. Businesses typically benefit from a 50 - 100+ times rate of return, when measuring the cost of an aorist Lean 6 Sigma or Lean training course and coaching against the benefits derived from applying it the very first time in their mine.
