Gold is often trapped as fine grains within larger grains of heavy minerals.7 With the local amalgamation method, the fine gold is not liberated. To liberate the fine-grained gold, the heavy mineral concentrate is ground in the washing pan with a rock. The concentrate with a high proportion of gold is then mixed with borax in a small plastic bag.
