Digital productivity solutions for the mining industry

Our digital productivity solutions are designed to optimise mining processes and improve output and throughput while minimising downtime. Our smart sensor technology supports mining production processes from mining, crushing, and grinding through to flotation. This enables mines to optimise processes and maximise profits.

Key to our value offering is the ability to match smart sensor technology to precision diagnoses that identify errors or inefficiencies and produces actionable insights for improvement.

Our smart sensor -based digital productivity solutions optimise mining processes by providing:

  • truck load metrics including payload estimation, truck load volume, PSD and ore characteristics;
  • ore size and volume metrics including liner wear, bulk density, reduction ratios and crusher protection;
  • mill size and volume metrics including mill fill estimation, mill diagnostics and conveyor condition; and
  • pulp and froth metrics including froth and pulp states, grade and recovery estimation.

By matching our smart sensor technology to enterprise-grade diagnostic tools, we provide mining operations with process advisories, asset maintenance reminders and warnings, and violation warnings.

Our new line of people and workplace monitoring solutions further add value to mining operations by improving workplace safety through tracking PPE violations and event detection.
