Presentation Transcript

Slide 1: 

People’s Public School Bhanpur, Bhopal Session: 2011-12 Subject: Social Science Top ic: Mineral And Energy Resources Submitted To: Mr. Habib Sir Presented by: Deepak saxena , Ajay pandy , Anamika asati , Akshat rai , Vinay gautam , Amaan khan.

Introduction:: 

Introduction: In this presentation we are going to talk about our minerals. Their different types. We will also be discussing about the occurrence of different minerals and also how to conserve them. And then we would have a look towards the data of 2003-04 production of various minerals in various states.

Slide 5: 

MINERALS Energy Minerals Non-Metallic Metallic Ferrous Containing Non-Ferrous Precious Mica , Salt , Potash , Sulphur , Granite , Limestone , Marble , Sand Stone. Etc; Coal , Petroleum , Natural Gas Classification Of Minerals:

Metallic Minerals:: 

Metallic Minerals: Can be classed into three types: Ferrous Containing : Minerals that contain iron in them are said to be Ferrous Minerals. Eg:- iron ore, manganese, nickle . Non-ferrous : Minerals that dose not contain iron are called Non-Ferrous Minerals. Eg:- copper, lead, tin. Precious: those minerals that occur natutrally and have high economic value are known as Precious Minerals . Eg:- gold, silver, platinum.

Slide 7: 

Iron ore Copper Gold Metallic Minerals

Non-metallic Minerals:: 

Non-metallic Minerals: Minerals that appears to be dull and not really reflective can be said Non-Metallic Minerals . Eg:- mica, salt, potash, sulphur, granite, limestone, marble etc.,

Slide 9: 

Non-Metallic Minerals Gold Mica Sand Stone

Energy minerals:: 

Energy minerals: Minerals through which we obtain required energy for our industrial as well as daily purposes is known as E nergy Minerals . Eg:- coal, petroleum and bio gas.

Slide 11: 

Energy Minerals Coal Petroleum Natural Gas

OCCURRENCE OF MINERALS: 

OCCURRENCE OF MINERALS

Modes of occurrence:: 

Modes of occurrence: In igneous and metamorphic rocks. In sedimentary rocks. While decomposition if surface of rocks. As alluvial deposits.

1.In igneous and metamorphic rocks: 

1.In igneous and metamorphic rocks Minerals may occur in the cracks, crevices, faults or joints of these rocks. In most cases they are found when minerals in their different forms are forced upward through cavities towards the earth surface. They cool down and solidify as they rise up. Eg:- copper, zinc, lead.

2.In sedimentary rocks:: 

2.In sedimentary rocks: Here minerals occur in beds or layers. They form as a result of deposition and getting concentrated in the horizontal strata. Eg:- coal, gypsum, potash salt.

Clay stone:

3. While decomposition of surface of rocks: 

3. While decomposition of surface of rocks In this the removal of soluble constituents take‘s place and leaves residual mass of weathered materials that contains ores. Eg:- Bauxite.

Bauxite extraction: 

Bauxite extraction

4.Alluvial deposits: 

4.Alluvial deposits Minerals can also occur in sand of valley floors and the base of hills. These are called Placer Deposits . Minerals found here can not be easily corroded by water. Eg:- gold, silver, tin.

Alluvial deposit around Hudson bay:

Slide 22: 

USES OF MINERALS IN VARIOUS INDUSTRIES:

Slide 23: 

Copper in chemical industries Manganese in paints Silicon, limestone etc in paste And fluoride in cleaning teeth's iron in automobiles Mica in electronic industries

Slide 24: 

Limestone in Cement industry Coal for power generation Natural gas in petrochemical industry as raw material & energy source Fuel from petroleum for automobiles

Slide 25: 

CONSERVATIONS OF MINERALS:

Slide 26: 

We need to conserve our mineral resources because even if they are more in quantity they are gonna to be come to an end some or the other day. Even if they are renewable resource the took millions of year to get renew. That’s why we need to conserve our mineral resources.

Slide 28: 

1.Distribution of Coal, Oil and Natural Gas

Slide 29: 

2.Distribution of Iron ore, Manganese, Bauxite and Mica

Slide 30: 

3.Distribution of Nuclear and Thermal power plants
