    once mining engineers know where gold is located and what other materials surround it, the mining process can begin. if the gold is located close to the surface, it’s mined with open-pit mining techniques. gold that’s located farther below the surface is collected with underground mining methods. large pieces of ore are made into smaller pieces, and then the sand grain-sized pieces are mixed with a cyanide
