Common gold minerals are: natural gold, silver-gold ore, gold telluride ore, gold telluride ore and so on. Gold is smelted from these minerals. There are three main valence states of gold, namely, Au0, Au 1+ and Au3+. Au0, which is common in nature, is natural gold. Au 1+ and Au3+ both exist or migrate in the form of compounds, and Au 1+ can form complex ion groups with elements such as s, f, Cl, h, o and n, such as [AUS]-, [AU2S3] 4-, [Au (SO4)]-, [au. Au3+ usually combines with Cl-S2-, SCN-,CN-and HS- to form soluble and highly active complexes, which exist in hot water. The hot water solution of this gold-containing compound flows with gold migration and comes to certain occasions (mostly fracture, unconformity and contact zone). When the physical and chemical conditions are suitable and the pH and redox conditions meet the requirements of precipitation of these compounds, gold mineralization begins. After continuous accumulation and finally mineralization, this is the rock gold deposit.
