Nick Wilshaw

CEEC Director 


Nick graduated from the Camborne School of Mines in 1980 with a BSc in Mineral Processing and an MSc from Queens University, Kinston, Ontario. In his early career he worked for English China Clays, involved with Kaolin and Calcium Carbonate processing. Initially working in R&D roles he helped develop dry media grinding mills from laboratory scale through pilot to full scale plants. He was integral in 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 with technology integration and optimisation of processes following the Georgia Kaolin acquisition. After returning to the UK Nick worked in senior roles in product development and marketing 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 and a laboratory facility for mineral evaluation. Grinding Solutions has a worldwide client base and carries out media and mineral testing 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 and BSc (Hons), in Mineral Processing at University College Cardiff. He has been involved in minerals processing, primarily in the PGM industry since 1980. Roles include Impala Platinum, Genmin, BHP and Anglo American, including senior operating management positions in South Africa and Zimbabwe; interspersed with periods in development, process design and project execution for concentrating, smelting, base and precious metal refining for plant installations. He formerly led Concentrator Technology at Anglo American Platinum, AAP, responsible for technical operational support, process plant design and optimization and technology development.

Chris 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. Areas of interest include sensor sorting of ROM ore; development work with HPGR circuits; multistage energy efficient ore processing circuits and mineralogical routine analyses on plant samples.
