16.3 Mineral Resources Figure 16.23: Gold-bearing quartz vein from California. Mineral resources, while principally nonrenewable, are generally placed in two main categories: metallic, which contain metals, and nonmetallic, which contain other useful materials.Most mining has been traditionally focused on extracting metallic minerals.Human society has …
3.2 Formation of Minerals. Minerals form when atoms bond together in a crystalline arrangement. Three main ways this occurs in nature are: 1) precipitation directly from an aqueous (water) solution with a temperature change, 2) crystallization from a magma with a temperature change, and 3) biological precipitation by the action of organisms. 3.2.1 …
