July 30, Weekly Geology Guest, Industrial Minerals

July 30, 2017
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
For the next several weeks we will delve into Industrial Minerals, While they are not glamorous, they are terribly important to our modern way of life.

Industrial resources (minerals) are geological materials which are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals) but are used in the industries based on their physical and/or chemical properties.[1] They are used in their natural state or after beneficiation either as raw materials or as additives in a wide range of applications.

Typical examples of industrial rocks and minerals are limestone, clays, sand, gravel, diatomite, kaolin, bentonite, silica, barite, gypsum, and talc. Some examples of applications for industrial minerals are construction, ceramics, paints, electronics, filtration, plastics, glass, detergents and paper.

What is an Industrial Mineral?
An industrial mineral is any naturally-occurring rock or mineral of economic value, exclusive of metallic ores, mineral fuels, and gem stones.   Industrial minerals may be located in igneous, metamorphic and sedimentary rocks (Bates and Jackson, 1984).
Industrial minerals that form from igneous processes include many pegmatite minerals, such as  muscovite, feldspars, spodumene, tourmaline, and beryl, as well as the igneous rocks themselves.  The latter, including granite, diorite, and gabbro, may be valued for their durability and beauty. 
Industrial minerals that are formed as a result of metamorphism include the rocks slate and marble, as well as minerals asbestos, wollastonite, garnet, and talc.
Industrial minerals occur in marine sedimentary rocks (limestone, dolomite, salt, gypsum) and non-marine sedimentary rocks (sand & gravel in stream deposits).
Classifications of Industrial Minerals:
Industrial minerals can be subdivided into two basic groups based on uses:
Fertilizer and Chemical Minerals:
bullet These are minerals essential for growing food (mostly potassium, nitrogen, phosphorus) and in many chemical applications (e.g. salt, sulfur, boron, soda ash).
Construction and Manufacturing Minerals:
bullet These are minerals and rocks that are used extensively in our infrastructure,  mostly in roads and buildings.

We will now start down the Industrial Mineral dusty trail and start with aggregates.

Enjoy the adventure!
