MINERALSA mineral is a naturally occurring substance that is solid and stable at room temperature, represent able by a chemical formula, usually a biogenic, and has an ordered atomic structure. It is different from a rock, which can be an aggregate of minerals or non-minerals, and does not have a specific chemical composition. The exact definition of a mineral is under debate, especially with respect to the requirement a valid species be a biogenic, and to a lesser extent with regards to it having an ordered atomic structure. The study of minerals is called mineralogy.
DIFFERENT KINDS OF MINERALS
TYPES OF MINERALS
METALLIC MINERALS Metallic minerals contain metal in raw
form.Metals are hard substances that conduct heat and electricity and have a characteristic lustre or shine.Iron ore,bauxite,manganese and chromites contain iron.

NON – METALLIC MINERALS
EXTRACTION OF MINERALS Minerals can be extracted by; Mining Drilling Quarrying
MINING It is the process of taking out minerals from
rocks buried under the earth’s surface is called Mining.
2 TYPES OF MININGOpen – Cast MiningMinerals that lies at shallow depths
are taken out by removing the surface layer is called as Open –Cast Mining .
Shaft –MiningDeep bores, called shafts have to
be made to reach mineral deposits that lie at great depths . This is called shaft mining.
2 TYPES OF MINING
DRISTIBUTION OF MINERALS Minerals occur in different types of rocks. Some are IGNEOUS rocks , some in
metamorphic rocks while others occur in sedimentary rocks.
CONTINENT – WISE DRISTIBUTION OF MINERALS
Asia CHINA- Iron ,TIN ,antimony AND TUNGSTEN. INDIA-IRON, MANGANESE, ZINC AND MANY OTHER
MINERALS. INDONESIA & MALAYSIA-THE CONTINENT
PRODUCES MORE THAN HALF OF WORLDS TIN.
EUROPE IRON -ORE DEPOSITS- RUSSIA,UKRAINE,SWEDEN
AND FRANCE. MINERAL DEPOSITS OF
COPPER,LEAD ,ZINC,MANGANESE AND NICKEL ARE FOUND IN EASTERN EUROPE AND RUSSIA.
CONTINENT – WISE DRISTIBUTION OF MINERALS
NORTH AMERICA CANADIAN SHIELD-IRON –ORE, NICKEL,GOLD,URANIUM
& COPPER . APPALACHIANS REGION-COAL WESTERN CORDILLERAS-COPPER,LEAD,ZINC,GOLD
AND SILVER.SOUTH AMERICA BRAZIL-IRON – ORE COPPER-CHILE & PERU SOUTH AMERICA-GOLD, SILVER,DIAMOND, ZINC,MICA
& CHROMIUM MINERAL-OIL –VENEZUELA,CHILE,PERU&COLUMBIA
CONTINENT – WISE DRISTIBUTION OF MINERALS
AFRICA RICH MINERALS-DIAMOND,GOLDAND
PLATINUM.AUSTRALIA LARGEST PRODUCER IN BAUXINE. LEADING PRODUCER INGOLD ,DIAMOND,IRO
–ORE TIN AND NICKLE.ANTARTICA IRON-ORE ,SILVER,GOLDAND OIL ARE ALSO
PRESENT IN COMMERCIAL QUANTITIES.
DRISTIBUTION IN INDIA
USES OF MINERALS Minerals are used in many industries. Minerals which are used for gems are usually
hard. Copper is another metal used in everything
from coins to pipes. Silicon used in the computer industry is
obtained from the quartz. Aluminum obtained from it’s ore bauxite
used in is automobile ,airplanes etc.
CONSERVATION OF MINERALS Minerals are non renewable resource. It takes 1000 of years for the formation and
concentration of Minerals. The rate of formation is much smaller than
the rate at which the humus consumes these minerals.
It is necessary to reduce wastage in the process of mining.
Re-cycling of metals is another way in which the mineral resources can be conserved.
