Overview Gold Process Mineralogy Part I


This treatise offers a brief but comprehensive glimpse of how microbeam analytical techniques have been applied over the last 20 years to resolve problems in gold ore processing. It covers only those techniques that are being used on a routine basis to study gold occurrences in plant samples. To facilitate the readers’ understanding, the microbeam techniques are introduced (and assessed) from a problem-solving point of view. These microbeam techniques form an intricate part of the comprehensive mineralogical and analytical approach used to establish on a direct and quantitative basis the occurrence of gold in tailings. Gold deportments determined by microbeam analytical techniques will identify opportunities for optimization and provide realistic targets for reducing the gold content in tailings streams. This approach has been applied in a number of gold operations, with the ultimate benefit of improved gold recovery.
