  2. Natural Gas  Natural gas, played vital role as main

    energy source to the rapid development of Bangladesh, production and consumption has been increased drastically during last decades.  There are 27 gas fields in Bangladesh till now
  3. Natural Gas • The discovered gas fields are at Sylhet,

    Chatak, Titas, Rashidpur, Kailastila, Habiganj, Bakhrabad, Kutubdia,Begumganj, Feni, Fenchuganj, Jalalabad, Narsingdi, Meghna,Shahbazpur, and Maulvi Bazar • Major gas producing fields are Titas, Kailastila, Habiganj, Rashidpur, and Jalalabad.
  4. OIL  The only oilfield of the country has been

    discovered at “Haripur” in 1986. It has an estimated in-place oil reserve of about 40 million barrels, with a recoverable reserve of about 6 million barrels.  The oil field produced 0.56 million barrels of oil in six and a half years, but production remained suspended from 1994. Bangladesh imports annually about 1.3 million metric tons of crude oil.
  5. OIL  For meeting the total requirement of commercial energy,

    Bangladesh imports yearly about 1.3 million metric Tons of crude oil.  Bangladesh imports annually about 1.3 million metric tons of crude oil. Besides these, another 2.7 million metric Tons (approx.) of refined petroleum products per annum is imported. Condensate is mixed with crude oil.  Major consumer of liquid fuel is transport sector followed by agriculture, industry and commercial sector which is mostly met by imported liquid fuel.
  6. COAL  Accordingly coal has been classified into the following

    ranks:  1. Lignite or brown coal  2. Sub-bituminous coal  3. Bituminous coal  4. Anthracite coal.  Coal first discovered in the country by Geological Survey of Pakistan (GSP) in 1959 was at great depth.  Geological survey of Bangladesh (GSB) continued its efforts for exploration that resulted in the discovery of 4 coalfields
  7. COAL  Commercial coal production at Barapukuria Coal Mine started

    in April 2003 with the expectation to produce 1 million short tons of coal/year.  Coal imported from India, China, and Indonesia is mainly consumed in brickfields both in public and private sectors, and in small industries.
  8. GRAVEL • A loose cluster of rock fragments • Seen

    on roads or beaches • Formed through erosion, weathering and concentrated action of rivers and waves of rocks • Mainly includes mineral quartz • Constructing roads, making concrete or even as decorations

  12. HARD ROCK • Refers to igneous and metamorphic rocks together

    • Igneous rocks are formed from the magma in the Earth’s mantle • Metamorphic rocks are formed when the other rocks have been subjected to heat and pressure
  13. Where is it found? 1.Maddhyapara subsurface hardrock 1974-75 the GEOLOGICAL

    Highways • Bridges & Dams • River Dykes, & embankments • Decoration pieces • Tiles
  15. LIMESTONE • Carbon sedimentary rock • Mainly made up of

    minerals like calcite and aragonite. • These minerals are the crystal forms of calcium carbonate (CaCO3 ).

  17. BEACH SAND MINERALS Beach sand which is a non- renewable

    resource consists of a number of useful minerals like: • Zircon • Rutile • Ilmenite • Garnet • Magnetite • Monazite • Kainite
  18. • Majority of the reserves are found along the sea

    beaches of Chittagong and Cox’s Bazaar district. • There are 17 placer deposits; 15 are in the Cox's Bazar-Chittagong sea beaches, of which 7 are from the Cox's Bazar-Teknaf sea beaches (Cox's Bazar, Inani, Silkhali, TEKNAF, Sabrang and Badarmokam), 7 from Maheshkhali Island, 1 each from Matarbari, Kutubdia and Nijhum islands, and Kuakata. • 20.5 million tons of raw sands which contains 4.4 million tons of minerals.
  19. Glass Sand • Glass Sand contains Silica and iron etc.

    • First discovered Sherpur district (in 1960) by GSP • Area of Glass Sand.

  26. Mineral and Energy Resources of Bangladesh Natural resources are resources

    that exist without actions of humankind. Richness in natural resource is the main indicator of socio- economic infrastructure for any country all over the world. The vital mineral deposits of Bangladesh are natural gas, coal, limestone, hard rock, gravel, boulder, glass sand, construction sand, white clay, brick clay, peat, and beach sand heavy minerals. At present, natural gas is the only mineral commodity significantly contributing to the national economy of our country. Energy and Mineral Resources Department are entrusted to make all approaches associated with the mineral and energy resources of Bangladesh.
  27. Importance of Minerals in Bangladesh Economy Bangladesh being a developing

    country is looking forward to use their natural mineral resources better to make our economy industrialized. Considering “Natural Gas” as the main natural mineral resource of our country. ✓For cooking purposes ✓Industrial development & raw material in Bangladesh ✓Transportation and Communication ✓Power source
  28. Importance of Minerals in Bangladesh Economy ✓Construction of roads and

    buildings ✓Development of Agriculture ✓Solving Unemployment Problem: I. Huge Employment Opportunity II. Transportation in the “raw material industry” and “industrialized product”. III. Making the agriculture sector more productive ✓Higher Standard of Living
  29. Appropriate Strategies to use Minerals and Energy Resources Strategies to

    use natural gas: I. Ensuring fund provision as per plan. II. Ensuring the drilling and development of well as per plan through the uninterrupted work procedure. Strategies to increase supply & use of coal: I. Creating mass awareness and mass involvement regarding the extraction procedure of coal. II. Constructing coal mining plan which is depended with the demand of the country.
  30. Appropriate Strategies to use Minerals and Energy Resources Strategies to

    use others minerals: I. We should create more reservoirs for storing minerals which will help us to meet the future demand. II. The government and the private companies should make maximum use of these minerals. Using our renewable energy resource properly by using the following some strategies: 1. Removing VAT/Tax for all type of solar accessories and wind turbine raw materials to reduce cost. 2. The govt. should make it mandatory to have all commercial buildings to install solar rather than residential buildings. 3. Implementing hybrid system.
  31. Conclusion For a developing country like Bangladesh, the major drawback

    is its expanding population and most the population is uneducated which makes the existing minerals insufficient to mee the demands of ots population. So, to overcome this problem more mineral resources should be discovered both in land and the ocean which would be important for achieving the goal of a sustainable future
