Mineral Resource - an overview | ScienceDirect Topics

Metallic mineral deposits (often referred to as 'ores') are rocks that contain economically valuable concentrations of metals. They are found in ore bodies that can be formed in different ways, for example, through hydrothermal, magmatic, metamorphic, sedimentary, and precipitation processes ( Brown, 2014; McKibben, 2005; Mungall, 2005; Ramanaidou and Wells, 2014 ).
