Testimonials

We’re proud to have worked alongside some of the largest mining companies in the world.

  • We have been experiencing in the plant an extended period of more frequent SAG mill overloads and reduced throughput. This is why one of the measures we took was to validate ore hardness compared to our previous data using the HIT machine. With these results you just sent us, we can see that the ore sampled in mid-October was on average more competent in SAG milling and softer in BM compared to our available data. Thanks again for your support with this!

  • We worked together with Toni back in 2008 for an expansion project of Codelco Andina - located in the central part of Chile. It was a challenging project because the nature of the requirement, addressed by the customer. In a few words, we needed to assess the extra fragmentation resulting from an ore pass, for the blasted material coming from the Open Pit and traveling into an Underground Mine. Because in this particular operation, the primary crusher and the mill itself was located underground in both cases. SimSage's approach was state of the art at that time and Toni conducted a detailed analysis of the particle size distribution transformation due to the free fall of blasted material increasing the fines fraction the customer was looking for and improving the SAG throughput. Not just a very qualified person, also a very kind guy to work with. I absolutely recommend SimSage services and I look forward to future collaborations.

  • We first consulted Toni for a major upgrade of our mill grinding circuits. His input was one of the key factors enabling us to save costs and time on the major project. Tony possesses a strong combination of hands-on experience and technical grinding simulation expertise and we continue to consult him on other initiatives at our operation.

  • ME Elecmetal has been using the services of Dr. Toni Kojovic for several years. His input has benefited our organization on many levels: internally as an expert reviewer and trouble shooter of proposed and installed Mill Liner designs; and externally as a respected comminution resource for our valued clients. As a global company, ME Elecmetal is committed to providing our clients with unsurpassed products and services and Dr. Kojovic has been a contributor in achieving this goal. In addition to being the keynote speaker at our Annual Customer Workshop in Chile, as a comminution expert, we invited him to present specialist topics to three of our customers, El Teniente, Los Bronces and Escondida. Dr Kojovic's expertise, and the success of his presentations has greatly enhanced the service that we provide to our clients and we hope to build on this model of client engagement through a sustained collaboration with Dr. Kojovic.

  • In 2015, SimSAGe was invited to help Antamina develop a crushing protocol for drill core samples to enable estimation of the ore breakage hardness as part of our standard geochemical sample preparation. The particle size distribution of the resulting crush was used to derive a model which proved to be robust and predictive for the Bond Work Index, now routinely incorporated in the Antamina block model.
