Fluorite:









 Has a glassy luster and makes cube like crystals and 4 excellent, octahedral.

 Fluorite is used instead of glass in some high performance telescopes and camera lens elements.

Galena:









 Color is lead-gray, has cubes or massive and 3 perfect at 90° cleavage.

 Galena is the most important ore of lead. Silver is often produced as a by-product.









Garnet:









 It’s a glassy lustre, 12 or 24 faced crystals and has a hardness of 7.

 Garnet uses include: gemstone, sand paper.





Gold:









 It has a Gold yellow color, streak that is yellow, and crystal form of flakes, grains, massive

 Most of the gold that is newly consumed or recycled each year is used in the production of

jewelry.

 Matallic lustre and a black colour

 Is one of the minerals that make up a iron ore.

 Is one of the only magnetic minerals.

Malachite









 Malachite has a vibrant green colour with a pearly look.

 Is a copper ore, which makes its uses far more advanced





Mica

Muscovite Biotite









 Muscovite has a white/pink even a translucent colour and a glassy/vitreous lustre

 Biotite has a silver/black colour and a metallic/glassy lustre

 Mica can be used as a insulator for high voltage electrical work

 Muscovite can also used as a see through glass type in high heat machines



Molybdenite









 Molybdenite has a bluish silver look with a metallic lustre and a flaky form

 Molybdenite is the only mineral that makes a molybdenum ore. The ore can be made into a

lubricant

Olivine









 Olivine is named after its olive green colour. It has a vitreous lustre and white streak.

 Olivine is commonly used in jewellery, brinks, and refractory sand.



Pyrite









 Pyrite has a brassy yellow colour and a metallic lustre. It has a cubic crystal form as well.

 The creating of a chemical for the paper industry and a acid for the chemical industry. Although it

as a iron ore because of the acid it makes it useless in most businesses
