Metallic minerals are elements or compounds that are generally hard, shiny, malleable, and usually have good electrical and thermal conductivity and high density.
Cleavage is the way minerals split apart naturally. Some minerals split into cubes, and some are split to irregular shapes. To measure the hardness of a mineral, Mohs scale is used. It is a 1-10 scale. Diamond is rated as 10 in that scale, and very harder than talc, which is rated as 1. Metal. Metals are known to human kind for a very long time.

Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.
A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes.A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids.The study of minerals is called mineralogy..
