:: Technology Transfer of AMIRA Thickener Project Increased  

Two sponsor meetings for P266D have significantly increased the technology transfer aspect of the thickener project. The September meetings, held in Brisbane and Johannesburg, also succeeded in exposing the project technology to more than 20 new sponsor representatives. Companies represented at the meetings, facilitated by AMIRA International, included De Beers technical centre and most of their mining operations, Anglogold, Ticor South Africa, Aluminum Pechiney, Angloplats, BHP Billiton and Rio Tinto.

Dr John Farrow, CSIRO, outlined the finalisation of the population balance model of flocculation and demonstrated it could predict the formation and size of aggregates under the full range of process conditions. “A cost benefit analysis currently underway is showing significant returns to sponsors from the project," Dr Farrow said. “There are also new tools for companies to use in the ‘Thickener Expert’ CD available to project sponsors."

The Johannesburg meeting was the first for the project held in South Africa. The meeting included a Project Workshop, a Sponsor In-House Project and site visits to Ticor Hillendale and De Beers Kimberley, which have both recently installed high rate thickening technologies, supplied by GL&V. The site visit allowed close inspection of project site trials at Hillendale. Dr Farrow discussed development of project extension P266E. AMIRA will now prepare a development schedule for the extension and circulate it to sponsors.
