Gold smelting is an essential process in the journey from raw material to pure gold. Smelting is the process of heating and melting the gold concentrate to separate it from other impurities and achieve a higher level of purity. This crucial step plays a significant role in transforming the gold concentrate into a more refined and usable form.
