Abstract:
After introductory remarks on physical characteristics, minerals, mineral processing and economic impact, the author will explain the four main methods to treat ores of gold and silver. These are gravity concentration, amalgamation, froth flotation and cyanide leaching. The methods will be illustrated with photos taken by the author during his career in mining and engineering in Latin America and other parts of the world. Note this presentation will take place in the Gehoorzaal, for optimum projection of the photos.
