Maelgwyn Mineral Services says it has officially opened its new combined Maelgwyn Africa and Maelgwyn South Africa premises in Boundary Park in Johannesburg, South Africa.

The new facility offers over 4,000 sq.m of floor space housing state-of-the-art offices, workshops, metallurgical and analytical laboratories, together with a world-class metallurgical pilot facility, the company says.

The metallurgical lab and pilot plant mostly undertake commercial mineral processing evaluations for process design and development purposes to bankable feasibility study level with bespoke solutions and fast reporting times undertaken by experts in the field of minerals processing, Maelgwyn explained.

The laboratory facilities also support the company’s proprietary technologies, including Imhoflot Flotation and the Aachen Reactor. These technologies have found favour across the globe in associated processes such as Leachox for precious metal recovery, Aachen Assist Leach and MMS-CND cyanide destruction.

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.
