Gold Dore Bars smelting

Gold Dore Bars smelting

A dore bar is a semi-pure alloy of gold, usually created at the site of a mine. We normally perform the smelting from gold nuggets into dore bars at the buyer’s request and in his/her presence. Sample essaying is conducted at any government gold testing facility to determine the purity.

Professional mining companies recover gold and other precious metals in quantities sufficient enough to pay refiners to do the smelting for them. But what can smaller scale recreational gold miners do? Consider melting or smelting your gold, silver, and other metals yourself! But first understand that there is a big difference between melting and smelting.

Melting means to change something from a solid to a liquid by the application of heat. When the heat is removed, the melted material returns to its solid state. Its chemical content has not been changed. Smelting, however, is a metallurgical term. It refers to “burning off” the impurities that your gold might be mixed with, resulting in nearly pure gold.
