The value of timely decision making, system optimisation and continuous improvement is well understood from productivity achievements gained in industries more broadly. Mining operations are increasingly becoming data rich but remain relatively information poor. Getting information to key people who can drive improvements and translate that to value is the critical step in the industry’s digital transformation. Clarity is developing capability to facilitate digital transformation, by harnessing the significant miniaturisation of computing power to allow complex computation inside sensors and transmission of timely intelligent information. This can be integrated with traditional control interfaces or via Internet of Things (IoT) dashboards. An example is shown of how edge sensing has been implemented on a flotation cell to detect the interface level., and how this has enabled insights and real-time process improvement.
Information systems can now be implemented that allow fit-for-purpose visibility of high value operational issues using one-directional passive information flow to Internet of Things (IoT) dashboards
This becomes a viable alternative to the trending and historian software solutions typically offered by higher-end Distributed Control Systems
The IoT devices are sensor agnostic and can easily be integrated with legacy equipment commonly found in long life-of-mine operations.
This adjunct solution allows improvements to be driven at the supervisor or shift level.
Trevor co-founded Clarity Advanced Control in 2018 to translate science outcomes into industry-implementable products – in particular, to develop and commercialise the next generation of mineral processing instrumentation. He completed an MSc in Chemical Engineering at The University of Cape Town, South Africa. At the CSIR in Pretoria he developed a grounding in fluidisation for energy and mineral processing applications, with key deliverables including scoping, trial work, plant design and commissioning. He joined CSIRO, Clayton, in 2008 where he further developed skills in process engineering, flowsheet development, computational- and physical- modelling in the energy and mineral processing sectors. In this role, he gained a wealth of knowledge in process evaluation, costing, integration and scale-up.
