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.

Easy tests to perform at home include the streak test and the acid test. Difficult tests include the hardness test (requires specific tools like a Mohs hardness kit) and the specific gravity test (requires precise measurements and calculations).
A geologist might use a piece of tile to identify a mineral because the unglazed surface of the tile can serve as an effective tool for performing a streak test. This test involves rubbing the mineral across the tile to observe the color of the streak it leaves behind, which can be a key characteristic for mineral identification. The streak color can differ from the mineral's appearance, providing additional information for accurate classification. This simple method is practical and widely used in fieldwork and laboratory settings.
In some rock, it is not possible to visually detect a mineral. Tests must be done to identify the minerals which compose the rock. Such tests would include: reaction to acids, specific gravity, texture, and color.
Yes, you can usually identify the mineral salt by its taste. However, with most minerals one would apply a series of tests, eg hardness, flame test, colour, density, streak, shape in order to identify the mineral.

to identify a mineral
Hardness test: Determine the mineral's resistance to scratching using the Mohs scale. Streak test: Rub the mineral against a porcelain plate to observe its powder color. Acid reaction test: Apply a weak acid to see if the mineral fizzes or reacts, indicating its chemical composition.
Many igneous rocks can be identified by the position of their minerals.

Many minerals have similar color, and mineral color can be altered by trace amounts of impurities or by weathering. A better indicator would be the mineral's streak, which is the color of the mineral when powdered, although this characteristic can't be used alone in mineral identification.
The least destructive method would be to simply identify the desired mineral specimen by eye and pick it up.
