LinkedIn Profile for Endorsements and Recommendations


Hydraulic Tin, Cornwall

I was a vacation student at Hydraulic Tin, Bissoe, Cornwall in 1971.  I had the privilege of working for Richard Mozley on fine tin recovery with Mozley Concentrators.

Rooiberg Tin, South Africa

I was assistant plant superintendent at Rooiberg Tin in South Africa in 1978, and worked with gravity concentration for coarse tin recovery, and flotation of tin fines.


Mufulira, Zambia

In 1972 I started my working life in the copper smelter at Mufulira Copper Mine in Zambia.  Initially I worked on shift, operating the 50MW submerged arc electric furnace, before moving to the converter aisle.  Later I worked on anode casting to optimise anode quality and reduce scrap recycle.

In 1974 I moved to the concentrator, working initially on shift operations.  I later worked on projects to introduce an offline XRF analyser for process control, comparison of large (for the time) flotation cells, liberation and mineralogy in the regrind circuit, concentrate dryer burner type and oil consumption, improvement to vacuum disc filter performance, and metallurgical accounting.

Olympic Dam, South Australia

During the 1980s I was a member of BP Minerals’ Olympic Dam team, working in parallel with Western Mining staff on development of phase 1 of the Olympic Dam project in South Australia.

After the plant was commissioned I monitored production statistics and product quality, comparing results against a process model developed by the BP Minerals team.  This led to identification and elimination of the major production bottleneck.

Copper Concentrate Filtration

With Larox and Outotec I have worked on copper concentrate filtration projects globally, but most notably in Zambia, Botswana, China, Chile, Peru and USA.


Gold in South Africa

I worked on several major South African gold plants during the 1970s.  These were Merrill Crowe plants with residue filtration and zinc precipitation at Doornfontein, East Driefontein, and Venterspost that were part of Gold Fields of South Africa.  Development projects included introduction of an automated cyanide analyser, and commissioning of a particle size monitor as part of a multivariable grinding circuit control.

I later moved to JCI and commissioned one of the world’s earliest CiP plants at Western Areas gold mine in 1980.

BP Minerals

I conducted several gold plant feasibility studies with Seltrust Engineering/BP Minerals office in London.

In 1988 I spent several months assisting with the challenging start-up of a Canadian gold plant with high copper content in the ore.  

Coal-Gold Agglomeration

In BP Minerals I was a member of the team running a pilot plant in Ballarat, Australia in 1987 to demonstrate the viability of coal-gold agglomeration.  I subsequently co-authored several papers on the process and developed a computer model for rapid CGA plant sizing and costing.


My final year thesis at university was on solvent extraction of uranium.  My first hands-on experience was at West Driefontein Uranium Plant in 1978.

West Driefontein

Development projects at West Driefontein included optimisation of polishing filter precoat, and solving a problem with low conversion efficiency in the pyrite burning sulphuric acid plant. 

Western Areas and Randfontein Estates

I joined JCI in 1980, and after commissioning the CiP gold plant, I moved to the uranium plant project as plant manager designate.  I managed the neighbouring Cooke Uranium Plant at Randfontein Estates temporarily, to select and train new operators for Western Areas. 

The WAGM uranium plant was commissioned safely, on time and within budget, including technology not used previously for uranium in South Africa; high speed disc filters; hopper clarifiers; Davy McKee combined mixer settler.

Olympic Dam

During the 1980s I was a member of BP Minerals Olympic Dam team evaluating proposals for the uranium circuit, and removal of uranium decay products from copper, as part of my responsibilities.


Agnew (Leinster), Western Australia

I spent a short time at Agnew Nickel Mine in Western Australia in 1984 during a plant expansion project at the time when the mine was a joint venture between BP Minerals and Mt Isa Mines.  I was responsible for commissioning a new ball mill to increase the capacity of the grinding circuit.

I returned to Agnew as metallurgical manager and relieving resident manager in 1985/6.  The mine was producing difficult, highly oxidised supergene ore that had a very high MgO content.  The priority was to avoid exceeding MgO rejection limits for concentrate.  Simultaneously, drill core from high grade extensions to the mine was tested extensively in the metallurgical laboratory.  My assignment also included commissioning of a new tailings dam at the hottest time of the year, when recovering adequate process water to operate the plant was a challenge.

I drew up a list of plant modifications required to achieve capacity and recovery when the new ore sources became available.  These were implemented once the mine was acquired by Western Mining.

Fortaleza de Minas, Brazil

In 1987 I was seconded to Brazil to supervise a metallurgical testwork programme on drill core from the Fortaleza de Minas nickel deposit in Minas Gerais.

Nickel Concentrate Filtration

Since the mid-1990s I have worked on several projects with Larox and Outotec for the installation of automatic pressure filters for dewatering of nickel flotation concentrate.

Filter Technology and Sales

I joined the Finnish company Larox in 1991 to open their UK office, and to market and sell pressure filters.  This was a temporary departure from the mining industry as my projects were in chemical processes including penicillin, titanium dioxide, precipitated calcium carbonate, fungicide, and oil desulphurisation.  

I conducted a market study for the UK, identified potential industries, and initiated a targeted marketing campaign.  This was followed by process testing, leading to major sales.

I took on the role of managing director of Larox’s mainland European office between 1996 and 1998, splitting my time between the UK and Germany.

I then returned to working on mining projects as business manager for mining and metallurgical applications globally from 1999.  I continued in variants of this role until retirement in November 2015.

I have been involved with filtration projects in Chile, Peru, Mexico, United States, Canada, Australia, China, Kazakhstan and particularly Southern Africa - South Africa, Zambia, Botswana, Zimbabwe, DRC.  

Between 2006 and 2008 I took a temporary assignment as managing director of Larox Southern Africa based in Johannesburg.  During this time we achieved record results, built a strong and motivated team, and achieved compliance with HSE and BBBEE regulations.  I was most closely involved with platinum concentrate filtration in South Africa, and copper concentrate filtration in Zambia.

Larox was acquired by Outotec in 2009, but my role in global support of concentrate filtration projects and sales remained unchanged.

I retired from Outotec in November 2015 and registered Rock Art Consulting as my company for future consultancy.
