Refining of Gold Obtained by Other Processes (Amalgamated Gold) By far the greater portion of the gold won annually is obtained by amalgamation. Mercury is fed into stamper boxes or pans, so that it will have a chance of coming in contact with the gold as soon as the latter has been liberated by the crushing action of the stampers, or the grinding action of the pans.

Gold can be alloyed with as little as 4% silver to make an alloy that is 75% gold and 25% silver, but this will increase the hardness of the gold. On the other hand, making it too soft (lower than 10%) decreases its ability to be worked into thread or wire; 6-10% is ideal. The melting point of gold alloys ranges from 1800°F to 1900°F.

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along

In both cases, a low melting eutectic (gold-silicon: 363°C) is formed even if the concentration of silicon is very low and this eutectic occurs at grain boundary regions. This means that at temperatures below the solidus temperature, some melting of the alloy occurs locally on grain boundaries.
