AngloGold Ashanti’s research and development programme includes a range of initiatives in geology, mining, processing, engineering, safety, environment, marketing and knowledge management.
A combination of collaborative and in-house research is adopted. Collaborative partners include research organisations, universities, mining companies, mining service providers and contractors.
In addition, AngloGold Ashanti’s wholly owned subsidiary, ISS International Ltd, (ISSI), is a global company specialising in seismic monitoring of mines, engineering structures and earthquakes. The company initiates and undertakes both broadbased and focused research and development to enhance the safety of those working in mining by developing effective monitoring and warning technology systems. ISSI functions on the international stage and its involvement in seismic matters extends well beyond the mining environment.
AngloGold Ashanti is a signatory of the International Cyanide Management Institute (ICMI) and is committed to reaching compliance with the International Cyanide Management Code. All processing operations group-wide have been audited inhouse. Following external audits during 2007, seven operations were certified by the ICMI to fully comply with the provisions of the International Cyanide Management Code.
Extensive cyanide speciation studies have been conducted in collaboration with Mintek in Johannesburg at the various plants in the South Africa region to determine, on both a macro and a micro-scale, the environmental impacts of cyanide in residue material. Continuing projects cover cyanide measurement and control, cyanide recovery and cyanide destruction.
A project evaluating the impacts of hypersaline water and cyanide on wildlife and the environment is under way in Australia in collaboration with ACMER. The results of this project have enabled Sunrise Dam to meet the stringent requirements of the International Cyanide Management Code regarding the management of cyanide in tailings.
The AuTEK project to develop new industrial uses for gold is based at Mintek. AngloGold Ashanti continues to support the catalysis initiative within the programme. This involves gold catalyst development for carbon monoxide oxidation, for use in fuel cells and in photocatalysis. A pilot plant for the production of gold catalyst is under construction. Close working relationships have been established with potential end users. Promising applications include gas masks, catalytic converters for diesel engines and catalysis of a variety of industrial chemical reactions.
