AMIRA International P1202 Far Field and near mine footprints – find the next generation of Tier 1 ore deposits
Paul Maney joins the AMIRA International team as Program Director - Mine to Metals

AMIRA International is excited to announce that Mr Paul Maney has joined as Program Director - Mine to Metal Business Unit.  Paul will be responsible to manage and grow the Mine to Metal (M2M) portfolio on behalf of our membership at AMIRA International, which encompasses mining, mineral processing, and extractive metallurgy value chain.

Paul has extensive experience in operational (mining and processing), strategic and technical roles across gold, iron ore, coal, base metals and mineral sands having worked for explorers, mid-tier producers 
and global mining organisations.  Paul joins us from BHP where he has held leadership roles in Group Technology’s Resource Engineering Technology team looking at tailings, water and energy; and Iron Ore’s Strategy, Development and Planning Department covering product management (quality, strategy and stewardship), metallurgy, processing, laboratories and mine geology.

Based in AMIRA International's Perth office, Paul will be working closely with his global M2M team with 
Mr Terry Braden in the United States, Mr Enrique Carretero in Chile, Mr Jeremy Mann in South Africa, and Dr John Visser, who is also based in Perth.

Paul can be contacted via email at paul.maney@amirainternational.com.
New members join AMIRA International

AMIRA International is pleased to welcome six new companies who have joined as members to enjoy the benefits of collaborative research.

Avanco Resources Ltd is one of the fastest growing copper and gold producers on the Australian Stock Exchange (ASX: AVB). Focused on Brazil, with an extensive portfolio of high-grade assets, from exploration, to development and production, Avanco is well positioned to deliver exceptional growth and returns in the near-term.

Thomspon Creek Metals Company (a subsidiary of Centerra Gold Inc.)  - Centerra Gold is a Canadian-based gold mining and exploration company engaged in the operation, exploration, development and acquisition of gold properties in North America, Asia and other markets worldwide. Centerra has two flagship assets, the Mount Milligan Mine and the Kumtor Mine which are located in Canada and the Kyrgyz Republic. Centerra Gold also acquired Thompsons Creek Metals in October 2016.

Clean TeQ Holdings Limited is the owner of the Sunrise Nickel/Cobalt/Scandium Project in NSW, Australia.  Clean TeQ Sunrise’s unique mineral resource, when combined with their proprietary ion exchange extraction and purification processing technology, positions Clean TeQ to become one of the largest and lowest cost suppliers of key cathode raw materials to the lithium-ion battery market – nickel sulphate and cobalt sulphate.  The Clean TeQ Sunrise Project will also produce significant quantities of scandium for the next generation of light-weight aluminum alloys for transportation markets.

Gengold Resource Capital Pty Ltd is an investment and management group with a track record of creating shareholder value by generating resource discoveries and development successes. GenGold principals have raised over $100 million in equity for exploration and development and are well supported by global banks and broking houses with investor loyalty in key equity markets in Australia, Europe and North America.. Gengold also have strong links to miners to facilitate project joint ventures or sales.

Newgold is an intermediate gold mining company which has a portfolio of five producing assets in top-rated jurisdictions. The New Afton and Rainy River Mines in Canada, the Mesquite Mine in the United States, the Peak Mines in Australia and the Cerro San Pedro Mine in Mexico (which transitioned to residual leaching in 2016), provide the company with its current production base. In addition, New Gold owns 100% of the Blackwater project located in Canada. 
Umicore NV is a global materials technology and recycling group, with about 10,000 employees and a turnover of € 11.1 billion in 2016. Umicore generates the majority of its revenues and dedicates most of its R&D efforts to clean technologies, such as emission control catalysts, materials for rechargeable batteries and recycling. Umicore’s overriding goal of sustainable value creation is based on an ambition to develop, produce and recycle materials in a way that fulfils its mission: materials for a better life.

2017 Ralston Medal awarded to Professor Bill Skinner, Associate Professor Max Zanin and Dr Bellson Awatey


AMIRA International would like to congratulate Professor Bill Skinner, Max Zanin and Dr Bellson Awatey for winning the prestigious 2017 Ralson Medal in Excellence in Physical Chemistry. Professors Bill Skinner and Max Zanin have been long-time collaborators for AMIRA International's P260 series of projects which is still ongoing in its current iteration - P260G Mineral Flotation.

The Ralston Medal for Excellence in Physical Chemistry recognises excellence and innovation in the application of physical chemistry which benefits industry. The medal is awarded biennially to acknowledge the most outstanding journal article in the field of physical chemistry published within the previous five years by staff, students or alumni of The Future Industries Institute or its predecessor, The Wark™. The excellence of the research contribution will be based on novelty‚ significance and impact as judged by the Selection Committee.

The winner of the 2017 Ralston Medal for Excellence in Physical Chemistry has been awarded to Professor Bill Skinner, Associate Professor Max Zanin and Dr Bellson Awatey for their paper entitled “Critical contact angle for coarse sphalerite flotation in a fluidised-bedseparator vs. a mechanically agitated cell”.

The nominated research relates to the challenge of recovering valuable mineral particles, by flotation, at coarse particle sizes. Key activities and outcomes of the work undertaken include:

  • Use of sophisticated surface characterisation techniques to examine the hydrophobicity of coarse particles through contact angle. This was achieved using an in-house built detachment force measurement apparatus (developed in earlier AMIRA P260 research, Xu et al., 2011) and innovative use of an environmental SEM to directly measure water droplet contact angles on the surfaces of individual mineral particles.
  • Successful flotation, using the HydroFloat Cell, of coarse sulphide particles (real ore) from 250 um to ~1.2 mm with high recovery.
  • Demonstrating that the low turbulence in the HydroFloat cell – in keeping with the prediction of the Wark Flotation Model – allowed such coarse particle recovery at critical contact angles far lower than possible in a conventional agitated flotation cell. The implications of this are far-reaching, indicating that far less collector is required, providing an additional, significant saving to operations.
  • Newcrest Mining, also a sponsor of AMIRA P260 and supporter of this work, has subsequently commissioned Eriez Flotation for a HydroFloat pilot scale facility at one of their Australian operations.
  • The value to the industry is in both significant energy savings and improved performance in metal recovery and throughput in the beneficiation of low grade ores.
