Business Challenge

With our client being in it’s final stages of ramp-up to full production of its gold processing plant, their technical team were constantly seeking to help the company’s mining operations increase their profitability and were challenged to find solutions that created sustained improvement without spending additional capital.

Approach

Focusing on areas that would have an immediate positive impact on plant productivity, advanced analytics, combined with technology and expertise where used to uncover hidden value. With a focus on quantifying the proportion of lost throughput opportunity associated with ball mill recirculating load, an opportunity was identified to improve milling circuit throughput via tighter power draw control.

Leveraging the Galaxy Engine™ multiple data sources were fused into an integrated data model. Then with added subject matter expertise, Interlate developed an interactive decision tree, which generated discrete operating states for further interrogation. Further analysis of these states in collaboration with our client’s operations team uncovered a set of power draw operating tactics for the site to use to reduce throughput constraints.

Value realised

In just a few weeks, a 2% improvement in plant throughput was identified resulting in an annual revenue improvement of $4.2M per annum for the client.
