Upon inspection of the list one would notice the absence of China, Russia and India. These countries use similar, but in most cases more elaborate classification schemes. The difference between a resource and reserve basically boils down one thing: a feasibility study. Not included in the classification, but often mentioned is a mineral occurrence.

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) …

Classification is also based on whether the deposits are magmatic, metamorphic, or sedimentary in origin, as well as the geological age during which they formed. Finally, ore deposits can be classified based on whether their main minerals are metallic, non-metallic, radioactive, or petroleum. Read less. Read more. Gallery. Report.

3. A CLASSIFICATION SCHEME FOR ORE DEPOSITS A very simple classification of ores is achieved on the basis of igneous, sedimentary/surficial and hydrothermal categories. This subdivision is very similar to one used by Einaudi (2000), who stated that all mineral deposits can be classified into three types based on process, namely …

The main goal is the find out the type of ores to be extracted from the given minerals. This technique has a wider scope than just identifying things. It can also be used to find the type of soil to extract the ores. This versatile method is not restricted to single ores and can be utilized for different ore deposit models and dataset types.
