AT LAST! A COMMERCIAL-SCALE CONTINUOUS CARBON ELUTION CIRCUIT

摘要

Over the years, the chemical processing industries have continued to move from batch to continuous processing in order to obtain better quality control, simpler designs, and often reduced capital and operating costs. One exception to this trend has been the carbon elution circuits in the gold industry. Although some success have been achieved on a pilot scale, no continuous elution circuit using Anglo American Research Laboratory (AARL) methods has ever been used on a commercial scale until now. This paper describes the continuous elution circuit which was recently commissioned at a major gold project. The paper also presents the economic justification for the selection of the process over conventional batch technology.
