Gold ore is a type of rock that contains valuable amounts of gold. It is typically found in veins or alluvial deposits and can vary in appearance, often showing a yellowish hue due to the presence of gold. Miners extract gold ore through various methods, including panning, sluicing, and hard rock mining. Once extracted, the ore must be processed to separate the gold from other minerals. This is usually done through techniques like crushing, grinding, and chemical treatments such as cyanidation. The final product is refined gold, which is used in jewelry, electronics, and as an investment.
