1. 9C: Minerals as Resources
Native Mineral
1)Metals:
Veins: metals are normally found in cracks in the rock
Placer deposits: minerals erode and wash downstream to be deposited onto beaches
Metallic luster
Good conductors
Remember Native mineral =1 element Can also be found in chunks or nuggets.

2. 9C: Minerals as Resources
Uses:
Gold (Au): Money, wires, tarnish-proof coatings in electronics, jewelry, art.
Silver (Ag): Coins, utensils, best conductor of electricity, photo printing.
Copper (Cu): Plumbing, architectural coverings, wires
Platinum (Pt): Car catalytic converters, future fuel-cell energy technology

2)Nonmetals Uses:
Diamonds (C):
Carat: Shows size of stone. (1ct=200mg)
Used on drills/bits to cut hard materials
Sulfur:
Sulfuric acid used in many industrial processes
Diamonds most often found in necks of volcanoes.
Misconception: Organic: things made of Carbon, well diamond is not from living thing, although it is made of Carbon.
Hope Diamond: largest blue diamond in existence.

4. 9C: Minerals as Resources
Compound Minerals are divided into families:
Remember compound mineral = more than 1 element

5. 9C: Minerals as Resources
1. Silicates: Contains mainly silicon & oxygen
More than 90% of earth’s crust
Feldspar: Most common silicate
Quartz: 2nd most common
Uses: glass, jewelry, ceramics, computer chip manufacturing
feldspar

2. Oxides: made of oxygen and one other element, usually a metal.
Chief resources of major metals used in industry.
Hematite

3. Sulfides: minerals made of one or more metals and sulfur.
Much like oxides.
Galena

4. Carbonates: Minerals containing 1+ metals ions and carbonate ion
Many caves are dissolved out of carbonate rocks
Uses: Cement, Paper, Steel
Calcite, Dolomite

5. Halides: Mineral salt compounds.
Most common: Halite (NaCl)
CaCl2: Used for ice on roads
Uses: Absorbs water from air, fertilizer, photographic chemicals
NaCl
