AllScan – Slurry Mineral Processing

The AllScan slurry analyser is the new benchmark in online analysis of critical slurry streams in mineral and coal processing plants.

The system does not require any sampling systems normally associated with other available technologies on the market.


Slurry Analyser for mineral processing

  1. The advantage of applying the AllScan as opposed to the Multistream XRF analyser is:
    1. Full stream analysis reducing the effect of sampling bias.
      1. Weighted error (WE)
      2. Integrated error (IE1)
      3. Periodic error (IE2)
      4. Fundamental error (FE)
      5. Grouping and segregation error (GE)
      6. Delimitation (DE)
      7. Extraction error (ER)
      8. Preparation error (PE1)
      9. Preparation error (PE2)
      10. Preparation error (PE3)
      11. All of above = Total error (TE)

Benefits are:

  1. Minimal requirement for pumping and handling of slurry
  2. No agitation of sampled material required
  3. No requirement for flushing circuits
  4. No requirement for fixed cutter cleaners
  5. Minimal requirement for additional piping in the multiplexing applications
  6. Direct online elemental analysis without latency in data provision
  7. No moving parts with little too no maintenance requirement
  8. Significantly lower cost of ownership.
  9. Pro-active control capability without latency in determining:
    1. Elements to be analysed
    2. Frequency of analysis (Assay update time)


  1. Improved yield
  2. Reduced reagent costs
  3. Reduction in waste management and cost
  4. Smaller footprint resulting in reduced structural steel requirement
  5. Improvement in metallurgical accounting
  6. Improved recovery rate through measurement of concentrate and tails in real time
