Sulfate is a compound composed of sulfate ion (SO42-) and other metal ions. It is an electrolyte, and most of it is soluble in water. Sulphate minerals are salts formed by the combination of metal elements (including ammonium) and sulfate. Because sulfur is a valency element, it can produce different minerals in different valence states in nature. When it combines the highest valence S6 + with four O 2 - to form SO42 -, and then with metal cations, it forms sulfate. In sulphate minerals, more than 20 metal cations are combined with sulfate. That is, sulfate containing sulfate is sulfate.
