gold refining

Gold refining is the process of purifying raw gold to achieve high purity, typically 99.9% or higher. It involves extracting gold from raw materials, such as ore, scrap, or dust, and removing impurities like other metals or contaminants. Common methods include chemical processes like aqua regia or electrolysis, where gold is dissolved and then separated from impurities. The refined gold is then melted and cast into bars or other forms for investment, jewelry, or industrial use. This process ensures the gold's quality, value, and suitability for its intended application.
