But the amount of gold in the earth is extremely small, so that mining is not really worthwhile. Generally there are two types of gold: primary gold (“mountain gold” from mines) and secondary gold (“stream gold”,“nuggets”). Above all the extraction of primary gold is associated with considerable effort. There are various methods to free...
