How does gold change from the time it is collected to the time it is ready to sell?

Gold undergoes several processes from collection to sale. Initially, raw gold is extracted from mines and then refined to remove impurities, often through techniques like smelting or electrolysis. After refining, the gold is alloyed, shaped into bars or coins, and hallmarked for purity. Finally, it is packaged and presented for sale, either through retailers or in the wholesale market.
