Seshat Consultants

Expertise: Drill/Blast & Mine-to-Mill Brisbane, Australia

Seshat Consultants is led by Dr. Sarma Kanchibotla, who 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 2002 Sarma received the AusIMM Mineral Industry Operating Technique Award for implementing the Mine to Mill project. Sarma has also implemented several large 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.

Sarma is now working on the Next Generation of Mine to Concentrator technology. The main aim 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.

Expertise: Comminution – Debottleneck AG/SAG/Ball mills and provide solutions to operations that are mill-limited to not sacrifice the primary grind (and recovery), and save energy along with OPEX for operations that are mine-limited.

Dr. Sanjeeva Latchireddi is the Managing Director of EEMS with over 25 years of experience. Sanjeeva is one of the world’s top comminution experts and an inventor of a novel pulp lifter with many commercial applications across global milling operations, achieving significant improvements in mill throughput and energy savings. He is recipient of AusIMM Mineral Industry Operating Technique Award in 2004 for invention of novel pulp lifter and its successful implementation in grinding mills.

EEMS is serving the mineral processing industry with guaranteed deliverables across a wide range of commodities using its patented and industrially proven technologies, to increase throughput of milling circuits, to optimize energy consumption and reduce OPEX for improved productivity and grind size.

EEMS’s Holistic modeling approach utilizes its proprietary models to identify bottlenecks related to Energy Spectra, Transport and Particle Breakage processes, and recommends and integrated solutions to ensure efficient milling conditions to achieve maximum grinding in AG/SAG and Ball mills.

The company leverages the skills and in-depth knowledge of its founders, proprietary modelling tools (FlowMOD®) and experience to measure, model, design and supply performance enhancing patented discharge systems (through VEGA Industries Ltd) to debottleneck AG/SAG and Ball mill circuits.

Surface Science Western

Expertise: Mineral surface characterization London, Ontario, Canada

https://www.surfacesciencewestern.com/about/our-team/
Dr. Stamen Dimov and Dr. Brian Hart – senior research scientists – from Surface Science Western (SSW) have been instrumental in providing expertise in mineral surface characterization to various global mining companies including Barrick Gold. SSW provides a variety of analytical services to the mining industry related to the discovery, characterization, and processing of valuable minerals. Some of the areas SSW has established itself as a “go-to place” for analytical services within the mineral processing sector include:

  • Determining the concentration and distribution of precious metals at low concentration levels (ppm-ppb range) in various mineral phases
  • Surface chemistry in relation to flotation selectivity: flotation scheme optimization and process control
  • Extraction technology: issues involved with sulfide oxidation in autoclaves and gold losses during leaching in response to preg-robbing by in situ organic material

As a consulting and research laboratory, SSW is also actively involved in research and development for the mining industry. Part of their mission is to work together with research partners from the mining industry to develop new applications and commercialize them as routine diagnostics tools.
