Welcome to the World Mineral Statistics electronic archive from the British Geological Survey (BGS). The BGS, and its predecessor organisations, have compiled production and trade statistics on a wide range of mineral commodities since 1913. From 1992 the information is contained in one of the largest and most comprehensive databases in the world;
Mineralogy is the systematic study that deals with the characteristics of the individual and group of minerals. The mineralogy has many more scientific branches. The first detailed narratives considering all the minerals at that time authored by Dana (1951), and with …
minerals is to a large degree related to the increased production of calcium carbonate slurry for paper. The total production value of Norwegian industrial minerals reached around 2370 mill.
mineralogical study also helps in the modal distribution of ore and gangue minerals which decides the grade of ore. Grain size of the minerals and their textural relationship helps in deciding the size reduction and liberation in mineral processing. An effective
1. Minerals should be used in a planned and judicious way. 2. Wastage of minerals in the process of mining & processing should be minimised. 3. Modern technology should be used for the exploitation of minerals. 4. Export of minerals should be minimised. 5.

and description of minerals. James D. Dana (1813 –1895) articulated a feasible classification of minerals based on the chemistry that had previously been proposed by Bezzelius (1779-1848). Although the microscope was used to study minerals early in
