The future of Minerals and Mining

Mineral processing plants need to economically and sustainably separate valuable minerals from waste. Numerous challenges exist for the optimisation of mineral processing plants in a cost-effective and energy-efficient manner.

At HRL we recognise that the challenge in improving the overall process is that making even small changes to optimise one section of the flowsheet can have unintended or unwanted impacts on several other sections. The key is to understand exactly what is happening within each area of a plant and with each aspect of the processing being undertaken, which requires a high level of holistic expertise.

At HRL that's exactly what we deliver, with experience across multiple industries. Unlike other service providers, we have decades of practical experience and unique high-tech testing capability along with advanced modelling techniques.

Over the years, we have partnered with some of the world's most reputable resources companies to solve problems and create millions of dollars of value including Rio Tinto, who consider us a strategic network partner.

When it comes to Minerals and Mining, you can count on HRL for Reliability, Efficiency, and Sustainability.
