Maelgwyn recently sponsored Minerals Engineering International’s Comminution 18 conference in Cape Town, South Africa. Maelgwyn’s Managing Director Mike Battersby presented a paper at the conference entitled “The Ro-Star ultra-fine grinding mill-theoretical, technical and practical development”. The paper was very well received with considerable interest being shown at Maelgwyn’s supporting stand. The stand showcased Maelgwyn’s entire technology range including Imhoflot pneumatic flotation and Aachen reactors for pre-oxidation and refractory gold processing.
