Nick Wilshaw

CEEC Director 

Nick graduated from the Camborne School of Mines in 1980 with a BSc in Mineral Processing. He then went on to graduate with an MSc from Queens University, Kinston, Ontario.

Nick has been involved in the mineral processing industry since graduating. In his early career he worked for English China Clays, where he was involved with most aspects of Kaolin and Calcium Carbonate processing. Initially working in R&D roles he was involved with developing dry media grinding mills from laboratory scale through pilot to full scale plants. He was integral in the commercialisation of the ECC Sand Grinder into the non-white minerals industry, with initial work on the Century Zinc project and Pasminco Elura. These grinders were subsequently developed into the Metso SMD mills. Nick spent 2 years with ECC in Georgia, USA involved with the technology integration and optimisation of processes following the Georgia Kaolin acquisition. Following his return to the UK Nick spent a period in senior roles in product development and marketing roles for novel products in non-paper applications.

In 2000 Nick started his own consultancy business focusing on industrial minerals and processing. In 2003 he started Grinding Solutions Ltd incorporating consultancy in the industrial & metalliferous mineral processing with a laboratory facility to allow for mineral evaluation. Grinding Solutions has a worldwide client base and carries out media and mineral testing with the aim to determine the most efficient methods for stirred media milling. The business now considers itself to be a world leader in fine grinding focusing on reducing comminution energy and optimising media selection and use in stirred media mills. Grinding Solutions has recently further expanded its business in flotation with the aim to help further reduce processing energy costs.
Their ultimate goal is to develop energy efficient solutions.

Chris Rule

CEEC Director 

Chris graduated from RSM, Imperial College London in 1979 with MSc and DIC in Extractive Metallurgy; earlier obtaining his honours degree, BSc, in Mineral Processing at University College Cardiff.

He has been involved in minerals processing, primarily in the PGM industry since 1980. He has worked for Impala Platinum, Genmin, BHP and Anglo American. His career to date has involved senior operating management positions in South Africa and Zimbabwe; interspersed with extensive periods in senior roles in project/process development, process design and project execution for ore concentrating, smelting and base and precious metal refining for multiple plant installations.

Currently he is Head of Concentrator Technology at Anglo American Platinum, AAP, based in Johannesburg, South Africa. In this role he is responsible for technical operational support, process plant design and optimization and technology development.

He has been heavily involved in initiating and leading a number of fine grinding using stirred milling projects in both mainstream regrind and flotation concentrate regrind applications; mostly IsaMillTM technology; with installed fine grinding units numbering 25 – a total milling power of 68 MW; installed at 10 plant operations.

Current areas of interest include sensor sorting of ROM ore; with an initial trial plant being installed in 2014 utilizing XRF technology; development work with HPGR circuits; multistage energy efficient ore processing circuits and mineralogical routine analyses on routine plant samples.

Simon Hille

CEEC Director

Simon Hille  is the Vice President Metallurgy and Process, Goldcorp Incorporated. Simon is also Chair of the Canadian Mining Innovation Council’s Energy/Processing Group.

Simon has 25 years of industry experience with a strong background in operations and a passion for sharing metallurgical best-practice and technical innovation.
