The main test of apatite is by its hardness, which is a 5 on the Mohs scale. Apatite can be cut as a gemstone, but it is relatively soft. Apatite also makes up sedimentary beds of phosphate rock. There it is a white or brownish earthy mass, and the mineral must be detected by chemical tests. 02. of 05. Lazulite .
Hardness: The resistance of a mineral to scratching or abrasion is termed hardness. To express hardness an arbitrary reference scale (Mohs scale) is used. ... Identification: "Phosphate rock" is a general term applied to natural deposits of minerals valued chiefly for their phosphorous content. Phosphate rock is often called
Phosphate rocks, also referred to as phosphorites, are sedimentary deposits with high phosphorus (P) concentrations. These rocks are one of the primary ore sources for P …
Phosphate rocks, also referred to as phosphorites, are sedimentary deposits with high phosphorus (P) concentrations. These rocks are one of the primary ore sources for P (Fig. 1), which in turn is a critical and non-renewable element for fertilizer production, upon which global fertility depends.The startling limitation of phosphate rock reserves has led to a renewed …
Dolomitic limestone is a carbonate rock of a rough surface texture that has a positive reaction with HCl. The indured phosphate composed of two types, one based on consolidated fine grains and the other with indured coarse grains. Both have a certain important hardness and are not easily friable.

The Mohs hardness scale measures a mineral's resistance to scratching.It is an unbreakable stone that ups the power of Rock-type moves. Rock-type moves are great against Fire, and Flying-type Pokémon, which are very common, so a Hard Stone is usually a powerful item in certain situations.
Hardness: Phosphate rock hardness is generally low, and the Mohs hardness is 5-5.5. Density: Phosphate rock is generally less dense than metallic minerals, with a range of 1.5-3.5 g/cm³. Luster: Phosphate rock luster can be …
solubility increases with increasing acidity, decreasing hardness, and decreasing temperature. Apatite may survive rock weather ing for a time to form a phosphate-rich residuum, but it …
Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals. Apatite has a relatively …
Phosphate mining provides the vital phosphorus element but it also generates an enormous quantity of waste rock [27].A quantity of 15 Mm 3 of phosphate mine waste rock (PMWR) is stored in the mine of Ben Guerir in Morocco. These waste rock contain three potential alternative aggregate for concrete: Flint (F), Phosflint (PF), and Dolomite (D) that were …
Properties of Phosphate Rocks. Anhydrous phosphoric acid forms prismatic crystals, which readily deliquesce in the air. As ordinarily prepared, concentrated phosphoric acid is a clear, colorless, syrupy liquid (specific gravity, 1.83), …
When I first stumbled upon the rock hardness scale, I realized how crucial it is for understanding geology. This scale not only helps identify minerals but also reveals their practical applications in various industries. From construction to jewelry making, knowing a rock's hardness can make all the difference. The Mohs scale, developed in the early 19th century, …
