• A key discovery
Discovery of the concept of Bubble Surface Area Flux (Sb) as part of Barun Gorain’s Ph.D. thesis. Sb is a key driver to mineral recovery in the flotation process. This has allowed a scientific way to flotation plant design and optimization.

• Advanced Mine to Mill at Cortez: corporate lead by Barun Gorain
High Commendations – Operations
Advanced mine to mill application at the Barrick Cortez Mine, by Malcolm Powell, SarmaKanchibotla, Vladimir Jokovic, Marko Hilden, Benjamin Bonfils, Anand Musunuri, Pamela Moyo, Sam Yu, Jace Young, Paul Yaroshak, EmrahYalcin, and Barun Gorain. This paper was presented at the 14th AusIMM Mill Operators’ Conference 2018 in Brisbane, Australia.
The CEEC Medal Evaluation judges commented that this was an outstanding paper building on the commonly applied mine-to-mill optimization where grade deportment and dilution, as well as blast movement during high-intensity blasting, are considered and evaluated.
