Minerals & Ores Testing Services

A Mineral is a naturally occurring substance found under the earth's crust, which has been formed as a result of various Geological processes occurring over substantial periods of time. It would not be wrong to mention that almost each & every utility or commercial substance in the contemporary world has been produced from a particular Mineral or a combination of various Minerals. Nothing can be conceived without Minerals. They constitute the backbone of any nation, since the Economic, Infrastructural & Industrial growth, besides the all-important National Security, of a country depends on its reserves of Minerals & the technology to extract & utilize them.

Minerals and Some of their Uses

Minerals have distinct & characteristic Physical & Chemical properties, & are the primary sources of all the naturally occurring Metals on earth. Minerals can be either Metallic or Non-Metallic, depending upon their compositions. A Mineral may consist of either only one Metal or a number of different Metals. The Study of Minerals is called 'Mineralogy'. The important 'General Characteristics' of any Mineral are as follows:

Spectro Analytical Labs Pvt. Limited
  • bulletNatural Occurrence, i.e., not produced 'Artificially' or 'Man-made'
  • bulletConstituent of Rocks
  • bulletInorganic Composition & Usually Abiogenic Origin, i.e., not produced from any living organism like plants & animals
  • bulletPhysical State - Solid; Stable at normal temperature ranges of the earth's surface
  • bulletFixed (or narrowly variable) Chemical Composition; Either a Pure Element, or a Chemical Compound, or a mixture of Chemical Compounds
  • bulletOrderly Crystalline Structure

There are over 4000 Minerals known to mineralogists, who have identified & characterized them based on their Physical & Chemical properties. Some common examples of Minerals are Limestone, Quartzite, Feldspars, Micas, Haematite, Gypsum, Gold, Asbestos, various kinds of gems etc.
