The drill bit that was used originally to discover the crude oil was faced with industrial diamonds . Fluids ,used for ease of well drilling, are almost entirely made from barite, bentonite, attapulgite, mica, and perlite. Clays and zeolites are necessary in the catalytic cracking process to produce gasoline and lubricants from crude petroleum. On our way to work we are literally riding on industrial minerals. Concrete pavement is composed of cement and aggregates .
Cement is manufactured from limestone, gypsum, iron oxide, clays, and possibly pozzolan.
The building we are about to enter is made from or of industrial minerals. If it is a concrete or stone or brick building.it is made entirely from industrial minerals. If there are steel structural members , the steel production process required fluorspar for fluxing, bentonite for pelletizing, and perhaps chromite for hardening. The making of steel requires the use of high grade refractory bricks and shapes made from bauxite, chromite, zircon, silica, graphite, kyanite, andalusite, sillimanite, and clays. Fiberglass batts may be used for insulation in office buildings, just as they are in our homes.
