Toronto, ON, Canada (February 21, 2019) S.H.O.T., or Selective Heat Ore Treatment is the end result of a collaboration to develop a new clean technology (cleantech) solution designed to transform how energy is used for crushing and grinding rocks in the mining industry.
Jenike & Johanson Ltd., the lead partner in the S.H.O.T. team, has brought together a diverse group of partners to present this technology to Canada at the Crush It! Challenge.
Impact Canada’s Crush It! Challenge, run in cooperation with the Centre for Excellence in Mining Innovation (CEMI), Goldcorp, and Natural Resources Canada (NRCan), challenges the mining industry to transform how energy is used for crushing and grinding rocks in the mining industry.
Consisting of three qualifying rounds, the challenge has already narrowed the field of competitors to twelve semi-finalists for Round 2. Semi-finalists will present their cleantech ideas to the challenge jury on March 3, 2019 at the #DisruptMining event held at the PDAC (Prospectors & Developers Association of Canada) in Toronto.
If successful in becoming one of the six finalists for Round 3, the team is eligible to receive $800,000 to prove their cleantech concept and will submit their technical report in November of 2020 in the hopes of being named the grand prize winner, in March 2021. The grand prize of $5 million will be awarded to fund the commercialization of the game-changing solution for cleaner, more efficient rock processing.
Who is the S.H.O.T. team?
- Jenike & Johanson Ltd. (Toronto) – Challenge Lead Partner – Specialized engineering firm focused on providing solutions to solids handling and processing challenges. J&J developed the science of bulk solid flow and remain the world leaders in its commercial application. non-linear flow scale-up must be considered in order to converge on the best commercial solution to move S.H.O.T. to industrial reality.
- SGS Canada Lakefield (Lakefield) – SGS is the world’s leading inspection, verification, testing and certification company providing leadership and innovation in the chemical, energy, and mining industries. SGS will house and operate the microwave testing to S.H.O.T.-treat samples at energy inputs of 0.3-3 kWh/t. SGS will provide pre- and post-treatment metallurgical characterization, including comminution, mineral liberation analysis (MLA), and flotation testing, and will assess the impacts on downstream processes.
- The University of Nottingham (UoN) (Nottingham, UK) – Microwave engineering with 200+ scientific publications, 180+ patents, 50+ PhD graduates in microwave processing and the design and scale-up of mineral processing microwave technologies. UoN holds the original intellectual property (IP) in microwave fracture together with a portfolio of key supporting IP.
- Teledyne Dalsa Inc (Waterloo) – Global leader in the design, production, installation and support of microwave generators for large-scale processing. Teledyne has developed experience and IP for the design, production, installation and support of internationally compliant and future-proof microwave generators for large-scale processing. Teledyne microwave technologies would form a key role in the supply chain as this technology moves towards commercialisation.
- Support from Canadian Industry: Teck Resources Limited, Agnico Eagle Mines Limited, RNC Minerals, Sherritt International, and counting*….
What is S.H.O.T.?
Selective Heat Ore Treatment
S.H.O.T. selectively heats the valuable mineral embedded in the host rock (gangue) using short intense bursts of microwave energy, establishing a sharp thermal gradient across the mineral-gangue interfaces to induce micro-fractures and for some ores macro-fractures. This dry, continuous, non-contact conditioning step delivers superior access to the mineral, which leads to significantly reduced comminution and recovery costs, and increased ore throughput and mineral recovery.
- S.H.O.T. uses a mass-flow materials handling system, based on flow properties, to present the ore to the applicator for the precise duration required.
- S.H.O.T. can be applied across a range of metals including copper, lead/zinc, nickel, gold, uranium, platinum group metals, and potentially diamonds.
What does S.H.O.T. deliver?
The impact of S.H.O.T. is different at every site.
- Improved accessibility to mineralization within competent ores
- Reduced energy
- Lower cost per tonne at higher throughput
- Up to 24% savings in specific comminution energy
- Reduced steel media and wear liner consumption
- A coarser primary grind – selective breakage helps liberate valuable minerals closer to their native grain sizes
- Reduced mineral losses from overgrinding
- Reduced material handling issues associated with fine materials
- Potential for heap leaching at coarser size which in some cases may make heap leaching a financially viable process option.
- Reduced negative impact on the environment
- Reduced carbon footprint
- Coarser tailings – more efficient water recovery and reduced risks associated with fine waste disposal
- Reduced slime and reduced reagent consumption
- Potential to magnify improvements by combining with other technologies, such as bulk sorting (avoid grinding some ore) or coarse flotation (Eriez HydroFloat™)
- Potential for reclassification of resources as reserves
