Smelting Key Terms. Roasting . In the case of carbonates and sulfides, a process called roasting drives off the unwanted carbon or sulfur, leaving an oxide, which can be directly reduced. Roasting is usually carried out in an oxidizing environment. Reduction. Reduction is the final, high temperature step in smelting.

Using Borax Flux to Refine Gold - Manhattan Gold & Silver

Aug 07, 2013 · With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
