  • Gold Mining and Processing: Everything you Need to Know

    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 solution to create a watery, mud-like mixture.
