Instead of minerals I would prefer to use the common description of "Rocks", that is a simple basic particle of the Earth people understand as the 'hard rock' minerals mining business which is a very much needed for the continuing evolution of the Cave Man.
But, the real meaning of "solid mineral material forming part of the surface of the earth" has been expanded to fit a "really solid" hyped ad-sense word advertising concept, or the rock rolled into an entertainment hall of fame. Where both of these perhaps "best uses" may only have 15 minutes worth of fame as a blip recorded on a on a "written in stone" geological record explaining both the raise and perhaps the fall of the "do-do homo erectus" better, known a the first of "mankind"— which itself is a mystical term as the man-race disappeared because they were not known to be "kind" at all. And, sadly, the do-do bird designation has to do with a cancerous stupidity for not appreciating the balance of Creator's experiment know as Earth.
Sisyphus, of Greek mythology, was punished for cheating by endlessly roll a boulder up a hill. Which in my experience is not half as difficult a thing to do when trying to define —and market— the throughly modern minerals I have had experience with since being a part of the 1955 strategic "Uranium Rush" to Moab, Utah.
The was first of then U.S. Office of Minerals Exploration (no longer funded) critical minerals list was Carnotite. Independent prospectors were encouraged to look for a major ore of uranium, with the chemical formula K2(UO2)2(VO4)2·3H2O — with a $10,000 bonus if successfull.
Other targets ores I have hands on, in-the field experience since then: cesium, chromium, cobalt, gallium, gallium, niobium, tantalum, titanium, and the platinum group metals, an unusual rare earth (REE) elements group — and Nepheline Syenite with a chemical Alumina-Silicate formula of Al2O3/ SiO2 / with the REEs lanthanum and cerium, important for strong glass, and niobium and zircon content favorable for sage age ceramics.
So what is the Nepheline Syenite War on Oregon's Table Mountain all about? Uniqueness vs Common Variety. The Department of the Interior, Bureaucrat of Land Management (U.S. Geological Survey / U.S. Bureau of Mines) versus the Department of Agricultural, U.S. Forest Service control over surface rights (USFS mineral soil and standing trees) in conflict with access to (BLM) mineral materials below the surface.
The only other USA supply of natural Nepheline Syenite is from a 3M deposit, in full production of some very advance fire barriers; they also are working on a road asphalt that can be laid direct onto existing dirt roads. They also most likely suppled the materials used in ELON Musks 'brilliant idea' solar roof tiles.
The minerals rights claim-holder, concerned about providing a economical answer for affordable housing, began experimenting with Nepheline Syenite's amazing use in expanding Portland cement into a fireproof (3,000 degrees for 4-hours) affordable replacement of a stick-built-home.
Fortunately/Unfortunately ECO Mining Milling became involved as the US registered contractor of this Swiss Army knife mineral FoamKrete™ when a USFS Plan of Action, mainly wanting a commercial licensed use fee to ECO haul in an EV truck keeping within load limits of the existing FS road system, was filed as :
