The extraction of gold is often thought of as the dramatic activity of extracting precious metal-bearing ore from deep underground. The ‘real value’ of gold occurs during the refining process; that is, where raw and impure materials are converted into pure, 24 karat gold that is suitable for trade, investment, and manufacturing. The gold refining company establishes the final quality and purity of the gold, which determines its compliance with international standards and its desirability in the marketplace.
