Telson Mining ready to experiment with metallurgical innovations at Campo Morado

Telson Mining, following a strong quarter of production from the Campo Morado mine, in Guerrero State, Mexico, is making plans to boost throughput and recoveries through the potential use of grinding, leaching and flotation technologies from the likes of Maelgwyn Mineral Services, Core Group and Glencore Technology.

The mine’s throughput averaged out at 58,100 t/mth in the March quarter, with total throughput for the quarter of 174,400 t being 4% higher than the December quarter. Some 11,013 t of zinc concentrate and 1,907 t of lead concentrate was produced over the period, compared with 9,974 t and 1,916 t, respectively, in the previous quarter.

Gold, silver, lead and zinc recoveries all improved, quarter-on-quarter, in the first three months of the year, the company added.

Ralph Shearing, Telson CEO and President, said: “These strong first quarter results continue to reflect our steady progression of improving the throughput and recoveries at Campo Morado. To this end, management intends to initiate a rigorous metallurgical testing program to advance through second phase testing the Leachox™ Process of Maelgwyn Mineral Services and the Albion Process™ of Core Group, both of which returned positive test results in first phase testing.”

He said this metallurgical testing program will also study the ability to increase base metal recoveries at microfine grinding with flotation recovery using Imhoflot Flotation (also Maelgwyn) and Jameson Cell (Glencore Technology) flotation technologies, both designed for such purposes.

“We are confident that additional recovery improvements are available utilising these exciting modern technologies which, if successful, can provide increased revenue streams,” Shearing added.

Maelgwyn’s Leachox Process consists of several Maelgwyn proprietary processes linked together including Imhoflot G-Cell flotation technology, ultra-fine grinding using the Ro-Star mill, Aachen Reactors and Aachen assisted cyanide destruction.

The Albion Process, meanwhile, is a combination of ultrafine grinding and oxidative leaching at atmospheric pressure. The feed to the Albion Process is refractory base or precious metal concentrates, where the sulphides in the feed are oxidised and liberated, allowing the target metals to be recovered by conventional means.

Maelgwyn Mineral Services’ Mike Battersby to lead CEEC Board of Directors

Mike Battersby, a global processing leader, has been appointed Chair of the CEEC Board of Directors.

UK-based Battersby has been a CEEC (Coalition for Energy Efficient Comminution) Director since 2012, bringing board expertise and more than 40 years’ experience in the minerals industry in operations, general mine management, technical consulting and corporate development to the role.

He replaces Joe Pease as the Chair of CEEC Board of Directors, who has served in the position for the past five years.

Battersby’s current board positions include Chairman and Managing Director of the Maelgwyn Mineral Services (MMS) group of companies in the UK, South Africa and Australia, and Director of Greenhills Technology International Ltd.

A chartered engineer, Battersby has operational experience with AngloGold, De Beers and Billiton in Africa, Europe, South America and Australia, plus more than 20 years working in the commercialisation of innovative technology, CEEC said.

In 1997, he co-founded the award-winning MMS, one of the leading technology development companies in froth flotation and gold processing.

He said: “CEEC’s mission is to share the latest energy-efficient comminution and minerals processing solutions to help miners achieve lower costs, reduced footprint, greater productivity, and enhanced business value. I am proud to have been appointed to lead an organisation with such an important mission and an impressive track record.”

“Positive actions on energy and productivity by industry are more important than ever, and CEEC’s work helps industry to collaborate, and identify and implement solutions to these challenges. Comminution, a major cost and energy consumer (3% global electrical energy), is key to tackling these issues.

“As the new CEEC Chair, my aim is to empower industry to apply practical tools to drive these improvements. CEEC’s free energy curves help mines to benchmark and explore best practice options. I look forward to working with the new energy curves team to develop further enhancements, and with industry to create complementary new tools that address the energy/water nexus.”
