This article reviews the South African Gold Mine Elution Process from the perspective of a thermal design engineer present when the elution concept was first developed. The author purchased the original heat-exchanger technology some 25 years later.
It offers a review of the original equipment capital cost optimization study, then reviews the lifecycle cost after a period of around 30 years.
It is a must-read for thermal designers, process engineers and interested parties. The information presented is unique and draws on previously unpublished communications and technology insights.
