minéral métallique

CONT: ... metallic deposits were formed by hot solutions coming from the interior of the Earth which emplaced the metallic minerals in rocks that had consolidated in a much earlier geologic time. ... In the other cases, metal-bearing solutions seep through permeable sedimentary rocks ... and precipitate the metallic minerals in pore-spaces or fractures or by replacement of non-metallic minerals.
CONT: Of the three classes of economic minerals (metallic minerals, mineral fuels, and industrial minerals), metallic minerals are those that may be used as a source of one or more metals. There are over 300 metallic minerals, the majority being sulfides and sulfosalts (60%) followed by oxides (25%) and native elements (10%).
