Geology Of Hard Rock Gold Deposits
Many pyrite and pyrrhotite minerals contain gold, which is often recovered when extracting copper from lode vein deposits. The purity of gold is stated in terms of fineness and carats (ct). Fineness is defined as the parts per 1000. For example gold with a fineness of 800 means it is 80% pure gold. Alternatively, gold that is pure is 24ct.
