MINERALOGY

How well did you know this?

Perfectly

building of rocks that contain elements or compounds found naturally on crust of the earth

MINERALS

How well did you know this?

Not at all

Perfectly

naturally occurring mineral containing a valuable constituent for which it is mined and worked

ORES

How well did you know this?

Not at all

Perfectly

they are named usually by chemical and mineral names

MINERALS

lead sulphide

galena

sodium chloride

HALITE

most abundant of the minerals

SILICEOUS MINERALS

never found in nature but it exist in silicate form

SILICON

they also contain calcium and magnesium which are metals bit not considered as sources of minerals

NON-METALLIC

contains carbonates, sulfates, and other compounds or native elements of sulfur

NON-METALLIC MINERALS

common metal ores

METALLIC MINERALS

found in pure form and do not exist in chemical combination with he other elements

METALLIC MINERALS

they are formed bt the mixture of metallic ore with waste materials

ORES can be called as "GANGUE"

power nuclear from

URANIUM

building infrastructure projects

IRON, & ALLOY such as STEEL

making soap, glass, enamels and washing powders

BORAX

manufacture of cement, mortar, and building materials

CALCITE

making explosive, fireworks and dyes

SULFUR

making pencil as lead

GRAPHITE

making optical instruments

QUARTZ

softest mineral on the earth

TALC

the hardest mineral in the earth

DIAMOND

making pwder for cosmetic, paints, ceramic and paper

TALC

making porcelain and enamel

FELDSPAR

known for their color, luster, and hardness

GEM MINERALS

pieces of jewelry

DIAMOND

10 minerals that are from METALLIC MINERALS

*IRON *NICKEL *COPPER *GOLD *SILVER *CHROMIUM *ZINC *MERCURY *LEAD *PLATINUM

3 examples of NON-METALLIC MINERALS
