leaching circuits, even when the ore is finely ground. The cause of low gold recoveries can be either through the presence of naturally occurring 'preg robbing' carbonaceous materials or gold physically 'locked' in sulphide minerals. The majority of gold ores are classified refractory because the gold mineralogy is contained in sulphides.

DIY Cone Mold (w/pics and questions) | Gold Refining

There is no method for separating gold from silver, or other precious metals, when smelting. The ore containing the metal when melted will form an amalgam – an alloy of gold and silver, or whatever precious metals are in your concentrates. Let the refinery separate precious metals – it9s really the easiest and cheapest in the long run.
