The gold loaded steel wool is manually removed periodically, subjected to acid digestion, drying and smelted to obtain bullion buttons. The bullion buttons thus obtained from table concentrate and steel wool are cast into salable bullion bars weighing 5 to 11kgs having a purity of 88-91% of gold, 8-11% of silver and balance impurity.
