Artisanal and Small-Scale Gold Mining Without Mercury

In direct smelting high-grade concentrate is heated until the gold melts. The liquid is then cooled to form a solid mass of gold dore, a semi pure gold alloy, that can reach upwards of 95% purity. To perform direct smelting, a miner, community mining consortium, or processing shop employs a crucible, a high temperature bowl designed for smelting.

What Is Smelting? - Manhattan Gold & Silver

Smelting Defined. Smelting is the process of extracting a metal from its ore. Hearing this, you might picture simply separating a piece of metal from a huge chunk of rock, but there's more to it. Ore is not just a mixture of rock and metal. The metal found in an ore is often oxidized so you need a chemical transformation to strip the oxygen away.
