Optimizing The Gold Mine By Increasing The Throughput

  • Using advanced analytics to boost productivity and ...

    Sometimes the changes suggested by a YET model can be relatively simple. At one gold mine, the use of an advanced-analytics approach based on sensor data revealed some unsuspected fluctuations in oxygen levels during the chemical-leaching process. Fixing the oxygen supply increased yield by 3.7 percent, worth up to $20 million annually.
