Gold ores are naturally occurring rocks and minerals that contain sufficient amounts of gold to be economically viable for extraction. These ores are typically found in various geological formations, including veins in hard rock and alluvial deposits in riverbeds. The concentration of gold in these ores can vary significantly, influencing the methods used for mining and processing. To extract gold from these ores, several techniques are employed, such as cyanidation and gravity separation. Once extracted, the gold can be refined and used in various applications, including jewelry, electronics, and investment. Understanding gold ores is essential for the mining industry and the global economy.
