Abstract
During the last 15 years about 700 t of gold have been consumed in the manufacture of low voltage electrical contactors, which, over a period of time, have become redundant and thus the gold component has become candidate for recovery. The results of laboratory and batch pilot experimentation, reported in this article, have demonstrated an average gold recovery rate of 95 per cent from used contactors by means of mechanical and chemical processing.
