Learning to identify rocks can be difficult when you are first started. Once you get the hang of it though you will start to notice patterns and similarities that will help you to identify rocks and minerals. A good way to start is by purchasing a book about rocks and minerals as well as doing some research on the web.
Mining minerals has way more than two advantages, but since you asked for 2, they create jobs (for miners) and not to mention the countless uses of the atual minerals and profits.
Minerals will have many different characteristics which can be used together to identify them.Density or specific gravity would be one element of the identification.You might also use: Color & Texture Melting Point Reactions with various chemicals. Identification of reaction products.
Physical mineralogy is the specific focus on physical attributes of minerals. Description of physical attributes is the simplest way to identify, classify, and categorize minerals, and they include:crystal structurecrystal habittwinningcleavagelusterdiaphaneitycolorstreakhardnessspecific gravity
The way a mineral naturally breaks is called its cleavage. The number and orientation of cleavages can help identify a mineral. For instance, micas have a single cleavage, and break up into flat plates. Pyroxines have two cleavages at 90 degrees to each other, and break into square prisms. Calcite has three at 120 degrees, and naturally breaks into rhombs. Different minerals may have the same cleavage, but it helps to narrow down a mineral's identity.
the least accurate way to identify a mineral
The observable color is the least dependable method of mineral identification.

Luster is not a good property for identifying minerals because many minerals look similar. Your best way of knowing which mineral is which is by measuring their hardness.

color im honest
Color alone is not the best way to identify a mineral because many minerals have the same color or more than one color. Mineral color can be highly variable and it can change depending on surroundings.

Streak test because minerals can vary in color, size and shape but their streak color will always be the same for that specific mineral. Calcite comes in many shapes and colors, but its streak is always white.
