Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.

Dense Media Separation (DMS) Plants. In a Dense Media Separation (DMS) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond (3.52 g/cm3), to which the diamond bearing material is added to begin the separation process of the heavier minerals from the lighter material.

Separating fine gold particles from black sands is one of the biggest challenges that gold prospectors have to deal with. This article will describe a simple and inexpensive method of capturing fine gold. Most small scale prospectors do not need to invest thousands of dollars to capture small placer gold dust. Using fine gold recovery methods, you can retain the vast majority of gold in your ...
