Calcite is a mineral made from carbonate and calcium. Halides - Halides contain a halogen element as the main element. Table salt (NaCl) is a halide mineral made from the halogen chlorine (Cl) and sodium (Na). Oxides - Oxides are minerals where the main element is oxygen. Chromite is an oxide mineral made from iron, chromium, and oxygen.

A mineral's specific gravity (SG) can be determined by dividing its weight in air by the weight of an equal volume of water. For instance, quartz with a density of 2.65 is 2.65 times as heavy as the same volume of water. SG = mineral mass/water mass. Cleavage.
