what is the process of gold mining

The entire process of gold mining can be broken down roughly into four steps prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. But the search today is more systematic and precise.
