ERS120H5 Chapter 3: Chapter 3 minerals part 1
Document Summary
Industrial minerals serve as the raw materials for manufacturing chemicals, concrete and wallboard. Ore minerals are the source of valuable metals like copper and gold and provide energy resources like uranium. A mineral is a naturally occurring solid, formed by geologic processes, that has a crystalline structure and a definable chemical composition: almost all minerals are inorganic. A material composed of a single or multiple elements held together by chemical bonds: covalent. No electrons are being moved, only shared. Transfer electrons from one atom to another: metallic. Weaker bond, weaker than both ionic and covalent. All the positive nucleus bonded together, cloud of area where electrons can move freely, no sharing: van der waals. Weakest bonds, positively and negative ends on them, and they result in either an attraction or opposite. True minerals are formed in nature, not in factories. Solidification of molten rock or direct precipitation from a water solution, did not involve living organisms.
