Elemental gold is an excellent conductor of electricity and heat, surpassed only by the other members of group 1B, copper and silver. Gold usually forms compounds (and complexes) by giving up either one of three of its valence electrons. It is commonly alloyed with other metals, as in jewelry, in proportions that yield desired hardiness and ...

The Mining Process 1. Mining - Open Pit and Underground — To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Successful gold mining is generally done in two steps: First is sampling or prospecting, and then, production. While some gold-bearing creeks and rivers tend to have gold values dispersed throughout their entire streambeds, there is generally not enough gold to make a small-scale mining operation payoff very well.

The more gold, the faster the process. This is because it is the friction of gold against gold which facilitates the cleaning process. Once the gold is glittery, rinse the soapy water out of the jar, pour the gold into a small (metal) finishing pan, and heat it up (outside and down wind) until the gold takes on a deep, natural, shiny luster.

There are several processes used in gold mining for extracting, and then purifying it. Amalgamation is a mercury based process which works because of gold's willingness to be dissolved by mercury. The mercury is applied on an ore, picks up the gold, and the resulting amalgam is distilled, with the mercury being boiled off to remove it.
