    Separating the gold from the ore. Smelting involves heating the gold with a chemical substance called flux. The flux bonds with the contaminants and floats on top of the melted gold. The gold is then cooled and allowed to harden in molds, and the fluxcontaminant mixture (slag) is hauled away as a solid waste.
