He has 40 years’ experience in the minerals industry in operations, general mine management, technical consulting and corporate development. An early career in various gold, diamond & base metal operations in Africa, Europe, South America and Australia was followed by over 20 years work in commercialising innovative technology.  In 1997 he co-founded MMS with inventor and engineer Dr Rainer Imhof.  Mike is Chairman of a number of associated international companies including Maelgwyn Mineral Services Africa Pty Ltd (MMS 48%) and Maelgwyn Australia Pty Ltd (MMS 100%).  In addition, he is also a director of Greenhills Technologies International Ltd. A privately owned mining and processing company looking to develop gold projects within Europe.

In 20 years MMS has become one of the leading technology development companies in the minerals processing industry. The company has invented, patented, developed and commercialised a range of different technologies and processes in the areas of froth flotation and gold processing. In 2001 MMS won the SmartWales award for the development of the G-Cell pneumatic flotation system. In 2006 the company won the “Celebration of Innovation” award for having the most innovative product to come out of Wales for the previous 25 years.

Mike has degrees in Mineral Processing (Cardiff University, Wales) and Entrepreneurship & Innovation (Swinburne University of Technology, Melbourne Australia). He is a Chartered Engineer and is a Member of the Institute of Materials, Minerals & Mining (London), the Australian Institute of Mining & Metallurgy and the Society of Mining Engineers of AIME (USA).

In 2012 Mike was appointed a director of the Coalition of Energy Efficient Comminution (CEEC) and in 2018 made chairman of the organisation. CEEC is a not for profit industry led international organisation whose aim is the acceleration of awareness of the industry to improve energy utilisation in the major area of comminution (size reduction).

In addition, Mike has previously sat on the boards of both the British Triathlon Federation (BTF) and its associate member, Welsh Triathlon Limited. The BTF is recognised as one of the world’s leading sporting NGB’s in areas of governance and leadership, whilst it has been the most successful triathlon nation at the last two Olympic Games.

Dr Rainer Imhof

Co-founder and Engineering Director

Dr Imhof has a M.Eng degree in chemistry and a PhD in mineral processing from University of Clausthal, Germany. He has over 40 years design, R&D and management experience in coal and non-ferrous process industries. Rainer has previously worked for Uranerz in Germany, researching various beneficiation processes. He then spent nearly 20 years developing technology for various mineral processing equipment suppliers in Germany including EKOF, KHD Humboldt Wedag  (now called MBE Coal & Minerals) and Allmineral. Dr Imhof is credited with the commercialisation of pneumatic flotation, whose early concept had been developed by Prof. Bahr at the University of Clausthal in the 1970’s. During his career Dr Imhof has been involved in the design and supply of many hundreds of flotation plants featuring pneumatic flotation in a whole range of applications including base metal, gold and industrial minerals. Rainer also used his theoretical background in bubble generation, shear and mass transfer to invent the Aachen Reactor for MMS. The development of the Aachen Reactor was specifically focused on solving a problem for gold processing operations. In his career he has had over 20 patents granted in his name covering various devices and processes including pneumatic flotation and mass transfer devices. Rainer is Chairman of GDMB (German mining association) flotation technical committee.

Rainer lives near Hamburg in Germany where he spends his time inventing, designing and improving technology offered by MMS, as well as flowsheet design and equipment selection for the companies projects.

Tim Sambrook

Tim Sambrook

Business Development Manager

Tim Sambrook is the Business Development Manager for Maelgwyn Mineral Services Ltd (MMS). He has 15 years’ operations management experience with both military and mining projects throughout the globe.

After graduating from Oxford with a degree in Chemistry (MChem), he joined the 1st the Queen’s Dragoon Guards (Welsh Cavalry) with whom he conducted long range reconnaissance and strike operations. After meeting his wife he was “persuaded” that he should consider a career with slightly more time at home; it remains his greatest achievement in convincing her that mining would be that more stable alternative.

Graduating Camborne School of Mines (CSM) with a Distinction in his MSc Minerals Processing Course, Tim initially stayed on to continue his research work in high temperature Bioleaching before being recruited to join SGS Minerals as a Project Metallurgist. At SGS, he specialised in fine gravity processing, environmental characterisation and diagnostic leaching. He joined the Drakelands Hemerdon Tungsten-Tin project in 2016 as a Plant Metallurgist with responsibility for retrofit operations and commissioning.

Mineco Ltd recruited him in 2018 to act as the Group Metallurgist looking at optimisation of their existing Pb-Cu-Zn flotation plants and to train the new concentrator staff at the Olovo cerussite project. He was asked to switch to the the Project Manager role in late 2018 to deliver the greenfield Olovo project; in this role he held additionally technical responsibility for the processing plant, dry stack tailings storage facility, staff training and environmental monitoring. The Olovo project was successfully delivered in 2020 and is the first new metalliferous mine in Bosnia in over 40 years. He has thoroughly fallen in love with the Balkans, the people and the excellent food.

He has research interests in fine mineral separation and optimising small – medium scale industrial mining. He is an active member of both AusIMM and IChemE.

Outside of work, he enjoys spending time with his awesome daughter, trail running in the hills and horse riding along the Cornish coast.

He then spent five years in lecturing and research activities at the Hanoi University of Mining and Geology.

Duong became a member of the Institute of Mechanical Process Engineering and Mineral Processing at the TU Bergakademie Freiberg as a PhD student in October 2013. In 2016, he joined the Helmholtz Institute Freiberg for Resource Technology – HIF in the processing group. Duong’s research activities focused on the flotation beneficiation of carbonate-rich phosphate ores, optimizing of flotation of the fine particles with an emphasis on cell hydrodynamics and process mineralogy. He also investigated enhanced mineralogical compositional information using automated mineralogy (Mineral Liberation Analyzer-MLA) and flotation modelling to obtain a better understanding of the model processes.

He also participated in various other research/ projects activities at HIF. These included  1) EU Horizon 2020 Optimore project – Flotation modelling of tungsten-/ Tantalum ores, 2) MultiDimFlot project, funded by the Deutsche Forschungsgemeinschaft (DFG), focused on the design of new flotation machine, 3) BMBF client project “REE Nam Xe” between Vietnam and Germany.

Duong is currently working as a mineral processing engineer  mainly supporting the EU H2020 project – FineFuture, in which MMS is a project partner investigating the applicability of its  innovative Imhoflot pneumatic flotation for ultrafine particles.
