Gold

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.
