5. The Non-Silicate Minerals
hematite
sapphire
The oxides are a family of minerals having structures consisting of close-packed oxygen atoms with metal or metalloid atoms occupying the spaces in between.
ruby
magnetite
Examples of oxides include:

6. The Non-Silicate Minerals
galena
cinnabar
The sulfides are minerals in which sulfur is combined with one or more metals.
Examples of sulfides include:
pyrite
sphalerite

7. The Non-Silicate Minerals
gypsum
baryte
The sulfates minerals have a crystal structure in which a sulfur atom is in the center of a tetrahedral arrangement with four oxygen atoms at the corners.
glauberite
anglesite
Examples of sulfates include:

8. The Non-Silicate Minerals
calcite
dolomite
The carbonate minerals contain the carbonate group, CO3, which is a carbon atom located with an equilateral triangle of oxygen atoms.
malachite
azurite
Examples of carbonates include:

9. The Non-Silicate Minerals
gold
copper
The native elements are minerals formed of a single chemical element.
diamond (carbon)
sulfur
Examples of native elements include:

14. Mineral Resources
Mineral resources are Earth’s storehouse of useful minerals that can be recovered for use.
Mineral reserves are already-identified deposits of minerals that can be extracted.
Ores are useful metallic minerals that can be mined at a profit.
Economic factors may change and influence a resource.

17. Metallic Mineral Resources
Gold, silver, copper, mercury, and lead are examples of metallic mineral resources.
Concentrations of these desirable materials are produced by both igneous and metamorphic processes.
