Ores that contain gold extracted by comminuting and followed by leaching with cyanide solution are known as "oxide" or "free milling" ores. However, gold recovery from most ores by cyanide leaching is not effective, with as little as 30 percent, or even lower, of the gold content of the ore being amenable to cyanide leaching.
