Gold extraction is the process of separating gold from its ore, which is the rock or mineral from which it is mined. This typically involves crushing the ore and using various methods, such as cyanide leaching or gravity separation, to isolate the gold. The extracted gold is then refined to remove impurities, resulting in pure gold that can be used for various applications. The most common method, cyanide leaching, involves dissolving gold in a cyanide solution, allowing it to be separated from other materials. Another method, gravity separation, relies on the density of gold to separate it from lighter materials. Both methods are essential in the mining industry for efficient gold recovery.
