The Non-Silicate MineralsThe oxides are a
family of minerals having structures
consisting of close-packed oxygen atoms with metal or
metalloid atoms occupying the
spaces in between.
Examples of oxides include:
hematite sapphire
ruby magnetite
The Non-Silicate MineralsThe sulfides are
minerals in which sulfur is
combined with one or more
metals.
Examples of sulfides include:
galena cinnabar
pyrite sphalerite
The Non-Silicate MineralsThe 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.
Examples of sulfates include:
gypsum baryte
glauberite anglesite
The Non-Silicate MineralsThe carbonate
minerals contain the carbonate group,
CO3, which is a carbon atom located with an equilateral triangle of oxygen
atoms.
Examples of carbonates
include:
calcite dolomite
malachite azurite
The Non-Silicate MineralsThe native elements
are minerals formed of a single chemical
element.
Examples of native elements
include:
gold copper
sulfurdiamond (carbon)

Mineral ResourcesMineral 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.

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.
