Develop Next Generation Mining and Concentrator Technologies

The main aim of NextGen Mine to Concentrator program is to achieve a step change in metal production, capital effectiveness, OPEX and energy signatures of the Mine to Concentrator value chain by developing and implementing novel feed preparation methods at the mine and novel comminution, classification and separation processes at the concentrator.

Sarma has over 30 years of industrial and research experience in the fields of drilling, blasting and mine to mill process optimisation. Sarma was involved in the development and implementation of mine to mill optimisation concept at several global mining companies around the world achieving significant improvements in mill performance and energy efficiency. In Y 2002 Sarma received AusIMM Mineral Industry Operating Technique Award for implementing the Mine to Mill project.

Sarma has also implemented several large research projects for Australian Coal Association Research Programme (ACARP) in open pit blasting in coal mines. One of the innovative blast design – called “baby decking” from these research projects has been implemented by several open pit coal mines on a regular basis to reduce coal losses.

Industry Engagement

Sarma worked as General Manager with the Metso responsible for strategic projects implementation and Business Development activities. He worked for Thiess mining contractors as Technical Manager, where he built organisational capability in the design and delivery of Drill and Blast outcomes worked for five years with Dyno-Nobel Asia-Pacific managing the DynoConsult in the east coast of Australia and Asia Pacific. Prior to coming to Australia Sarma worked with a major explosive supplier in India as Manager Blasting Services.

Collaborations

Sarma developed strong relationship with CSIRO and implemented several ACARP projects jointly with them. He is also advisor to a department of science and technology project that is being conducted by the Indian School of Mines, Dhanbad, India. He also worked with the University of Concepcion in the formation of SMI-ICE Chile.
