Is halite a mineral or not?
Halide minerals are salts that form when salt water evaporates. Halite is a halide mineral, but table salt (see Figure here) is not the only halide. The chemical elements known as the halogens (fluorine, chlorine, bromine, or iodine) bond with various metallic atoms to make halide minerals. All halides are ionic minerals, which means that they are typically soluble in water.
