We study geologic processes that concentrate known mineral resources at specific localities in the Earth's crust, and assess quantities, qualities, and areas of undiscovered mineral resources, or potential future supply. Minerals Information and Material Flow. Characterization and Identification of Critical Mineral Resources
Some minerals are even used to make hormones or maintain a normal heartbeat. Macro and Trace. The two kinds of minerals are: macrominerals and trace minerals. Macro means "large" in Greek (and your body needs larger amounts of macrominerals than trace minerals). The macromineral group is made up of calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur.
