Final Clean

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.

The Milling Process

The milling process has evolved from wheat being ground between two large stone wheels (although this process does still occur in a few mills). In a roller mill the practice centres around separating the three components of a wheat seed – the white endosperm, the outer bran layers and the wheat germ.

2017-9-7Gold/silver base metal concentrate deportment. Smelters typically pay 95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.

Melting is the process of changing a solid to a liquid using heat. Once this process is completed, the melted material cools and becomes a solid once again. Smelting, on the other hand, involves changing the chemical content of the material. When you smelt, you are "burning off" the other materials that your gold is currently mixed with
