  • Classification of ore minerals

    Ore mineral is defined as a mineral which contains a metallic element in a quantity that can be exploited and extracted for use at an economical cost. clays are rich in aluminum but since metal cannot be extracted from ordinary clays at an economical cost, these are not included among the ores of aluminum.

    Bauxite, an oxide of aluminum, however, is an ore of aluminum, since the metal aluminium can be recovered from bauxite by electrolytic refining at economic cost. the definition of an ore is, therefore, technology dependent. if a technology is developed to extract aluminum from clays at an economically viable cost, at a later date, these could also be included among the ores of aluminum.

  • Classification of mineral deposits geology for investors

    Natural concentration of an ore mineral in a massive rock body is defined as an ore deposit. it may be of any shape and form but its size is of real importance. a small patch or layer of bauxite, say one meter thick and a kilometer long will not make an ore deposit. the deposit has to be of considerable size and volume, often in terms of millions of tons, to qualify as an ore deposit. hence the definition of an ore deposit is also size dependent.

    A few non-metallic minerals are often found associated with an ore mineral. these have to be separated from the ore before the same is processed for extraction of the metal. these associated minerals are called gangue minerals and are worthless. quartz sio2 is a common gangue mineral associated with many metallic ore minerals.
