AMC is back at MINEX 2018 again this year with the fourth installment of our masterclass series and a presentation at the podium. The conference will take place 2-4 October in Moscow. This year we will focus on the practical side of developing and executing geometallurgical programmes during studies as well as for production improvement of existing operations. To complement the class, Ian Lipton will also present at the Business podium on the topic of geometallurgy.
AMC will again have a booth at the conference, and all those presenting will be available during and after the conference to engage clients and industry professionals in discussions on any topics of interest. Drop by to discuss any topics and to drop in your business card for a chance to win a premium bottle of Australian wine.
MASTERCLASS: GEOMETALLURGY: THE KEY TO UNLOCKING VALUE
Tolstoy Hall, 2 October 2018, 1.30 – 3.00 PM
Join us to explore the link between the geology of a deposit and the processing characteristics and how to benefit from those links!
Mark Chesher: Geometallurgy: the key to unlocking value.
Geometallurgy is becoming more prominent as companies recognize the benefits to be gained in matching the process plant to the expected ores. Studies are on-going at a variety of operating mines, and the lessons learned are being applied in studies to tailor processing and mining facilities to the life-of-mine ore types to optimize process flowsheet and economic benefits. This presentation will set the scene of the current general industry status and introduce the geometallurgy concepts to be explored in more detail throughout the Masterclass.
Rob Chesher: Transforming operations with geometallurgy examples of how geomet is used.
Geometallurgy is transforming mine operations and mine profitability across the globe. In this presentation, Rob Chesher discusses various ways that mining companies are exploiting the natural geological characteristics of their orebodies to increase throughput and reduce operating costs. With improved sensors and modelling capability, technologies such as mine-to-mill optimization and ore sorting are finding new applications and turning waste into ore. These step-change improvements are based on geometallurgical characterization of the orebodies and recognition of strategic opportunities. Recent developments and some case histories will be presented.
Ian Lipton: Predicting the comminution response of ores using Equotip hardness tester
The geometallurgical approach to orebody definition and mine planning seeks to map the response of ore to blasting, comminution and mineral extraction in three dimensions. The production-scale response cannot be measured directly but can be estimated from tests conducted on individual samples. This paper examines the use of the Equotip 3 hardness tester, a small, portable device that has been demonstrated to be an effective tool for the measurement of rock hardness. The tester is non-destructive and can be used during a drilling campaign to acquire large amounts of data from regular drill core at low cost. Case histories from two very different mineral deposits are presented; the Bowdens silver project in Australia, and the Chertovo Koryto gold deposit in Russia. Equotip surveys were carried out as part of geometallurgical programmes that integrated traditional logging and sampling with geochemical and metallurgical testing. The relationship of the Equotip data to geological logs, geochemistry, and bench scale comminution test results is examined.

PODIUM PRESENTATION- Session 11: Connecting Metallurgy to Geology
Tolstoy Hall, 4 October 2018, 2.30-4.00 PM
Join Ian Lipton to find out why geometallurgy is the foundation for optimizing mining projects in the twenty-first century!
A project that does not consider the geology of the deposit, mining, processing and waste disposal in a holistic manner, is unlikely to be delivering the best financial return to its owners. In this presentation, I present a framework for geometallurgical studies and discuss sources of geometallurgical data. Examples are provided to show how geological and metallurgical data can be correlated and used to establish predictive relationships. This allows the response of the ore to the processing flow sheet to be forecasted. Modeling these predictive relationships in three dimensions allows a project to be optimized using all the characteristics of the ore that drive cost and revenue, not just the grade. Importantly, geometallurgy can be applied from discovery, through pre-feasibility and feasibility and in to day to day operations, to improve project design, increase profitability and reduce risk.
