Determining the Rheological Properties of Mine Tailings
Tailings are leftover mineral byproducts of ore processing. The composition of tailings depends on the composition of the ore and the extraction process used to obtain the ore. Tailings typically consist of finely ground rock, processing chemicals, and small quantities of metals found in the host ore.

Mineral Hardness Britannica
Mineral Hardness Hardness (H) is the resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The minerals that make up the Mohs scale are listed in Table 3. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched
GeoMan's Mineral Identification Tests
To be classified as a mineral, a substance must be an inorganic, naturally formed solid, with a specific chemical formula and a fixed internal structure. For example, coal is not a mineral (it's organic), but snow meets all five (5) requirements and therefore is a mineral.
