Success Story - MagoSense


Ernest Henry Mining wanted to alter the pulp chemistry to improve the flotation performance in its plant.

In collaboration with our German partner, KIMA Process Control, we have developed a technological solution that grants you unprecedented visibility into the inner workings of your operating mill. Leveraging wireless data transmission, power supply and overall system robustness, these technical functions have already been proven and are widely adopted by leaders in the cement industry.

Our digital tool, MagoSense, is designed specifically for the mining industry, based on an existing, proven and used technology. Primarily developed for use on Semi-Autogenous Grinding (SAG) mills, it can operate on any type of tumbling mills and is adapted to the harsh mining environment.


After a series of promising laboratory test work, the decision was taken to convert the ball mill media charge from forged steel to high chrome media.


The improvements in the pulp chemistry resulted in an increase in copper and gold recovery of at least 1.3% and 1.0%, respectively. The additional copper in concentrate production reached up to 1430 tpy and 2840 ounces of gold per year, representing a $12.8 million USD increase in gross profit. Additionally, laboratory test work also indicated that the use of high chrome media could lead to reductions in pH during rougher, which would see no negative impact on the plant’s performance. In fact, once applied, this strategy realised an annual cost saving of $700,000 USD by reducing lime consumption.
