Minerals Engineering International (MEI) is a family run business based in the beautiful Cornish town of Falmouth, in the extreme South-West of England, and only a few miles from the UNESCO World Heritage site of the Camborne-Redruth mining area, once the world's greatest producer of copper and tin.


"MEI is the glue that binds the international mineral processing community together"
Prof. John Ralston, founding Director of The Wark and South Australian of the Year, 2007

MEI was founded in 1998 in order to disseminate information to the mineral processing community via:

  • High quality international conferences. Since their inception, MEI Conferences have developed a reputation for bringing together groups of high profile academics, researchers and industrialists, to discuss the latest developments in mineral processing and extractive metallurgy.

  • The Internet. MEI Online was launched in January 1999, to provide a central source of information for minerals engineers around the world. It acted as a portal for all things mineral processing, publishing news items, recently refereed publications, conference announcements and reports etc. In 2023, MEI took the decision to discontinue MEI Online as it was felt that the internet, especially social media, had moved on since the 90s and MEI Online was no longer needed.

  • Minerals Engineering. This internationally recognised, peer-reviewed journal is published by Elsevier Science, and was edited by Dr. Barry Wills of MEI until 2022, when Pablo Brito-Parada took over. Papers from MEI Conferences are published in a special issue of the journal.

Dr. Barry Wills

Barry Wills

Barry's career in mineral processing began in 1969, when he left Leeds University to work for 4-years in Zambia with Nchanga Consolidated Copper Mines Ltd. On his return to the UK, he worked for a year as a senior development engineer with Johnson Matthey Ltd, before taking up the post of Senior Lecturer at the Camborne School of Mines in Cornwall, where he was actively involved in the squash and cricket teams, as well as diving on some of the many shipwrecks around the Cornish coast. During his time at Camborne he found time to write the text-book Mineral Processing Technology, and in 1988 founded the Minerals Engineering journal. Barry left CSM in 1996 to work with CSM Associates on the organisation of minerals engineering conferences. In 1998 he joined forces with Amanda to form Minerals Engineering International (MEI).
In 2014 he was the recipient of the International Mineral Processing Council's Distinguished Service Award, and in 2017 with the IOM3 Medal for Excellence. He is an Honorary Professor of the Central South University, China
