Types of Minerals

Minerals are divided into two types namely metallic and non-metallic. 1. Metallic Minerals. Metallic minerals exhibit lustre in their appearance and consist of metals in their chemical composition. These minerals serve as a potential source of metal and can be extracted through mining. Examples of metallic minerals are Manganese, iron ore …

The process mineralogy of gold: The classification of ore ...

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked ...

Classification of Ore Deposits

Mineral deposits: Classification. Ore deposits are of such infrequent and random occurrence, of such modest size, and so different in composition in comparison with the generality of rocks, that they probably require an uncommon sequence of geologic happenings to bring about their formation.
