The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together. The gold ore is then pulverized using pressure to create very fine particles. These fine particles are then heated in a furnace to temperatures above 1064 degrees Celsius the melting point of gold.

Step 1: The process begins with drilling of blast holes which are supposed to be at least 40 feet deep and 16-22 feet apart. This is done to check if there is gold at the site or not. Step 2: The holes are then blasted in a controlled manner, to ensure minimum impact to the environment around.

The erosion process of water over time reveals the places in which large gold deposits can be found. Streams that cut through the rocks carry the smaller elements of gold down with them. Because of the malleable nature of gold, it rarely forms into nicely shaped crystals and mostly is found in lumps or irregular masses that filled the cracks ...

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or assays, that measure the gold content. In most cases, the gold is 99.9 percent pure. Workers cast the gold produced during refining into bars.

In all gold plating, the part is polished and cleaned as thoroughly as possible before the electroplating process starts. Gold plating will look uneven and smudged if the surface is dirty, oily, scratched or otherwise damaged. Modern electroplating begins with the creation of a metal salt using the plating metal, typically gold or silver.

The process eliminates the remaining impurities (if any) from the gold. The raw gold experiences a melting process and treatment with chloride. As a result, any impurities remaining with gold convert into chloride, which automatically gets removed from the gold. The result would be 99.5% to 99.99 pure gold.
