Gold

Vein, or lode mining, is the most important of all gold recovery methods. Although each ounce of gold recovered requires the processing of about 100,000 ounces of ore, there is so much gold deposited in rock veins that this method accounts for more than half of the world's total gold production today.

Gold Recovery : 8 Steps (with Pictures) - Instructables

The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery ...

Gold | Geoscience Australia

Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold. This is referred to as 'native gold'.
