Punjab, despite being known primarily for its fertile agricultural lands, houses a diverse range of mineral resources. These resources, though not as abundant as in some other states, play a crucial role in the state's economy and contribute to various industries. Let's delve into the details of mineral resources found in Punjab:
Major Minerals:
Coal: Punjab has significant coal deposits in the Salt Range, specifically in the districts of Attock, Jhelum, Chakwal, Khushab, and Mianwali. The coal is generally of sub-bituminous quality and is found in the Patala and Hungu Formations of Paleocene age.
Bauxite: Bauxite, the primary ore of aluminum, is found in the districts of Khushab and Chakwal.
Fire Clay: This type of clay, resistant to high temperatures, is found in the Salt Range and is used in the manufacturing of refractory bricks and ceramics.
Silica Sand: Found in Hoshiarpur district, silica sand is used in the glass industry and construction.
Quartzite: This hard, non-foliated metamorphic rock is found in Hoshiarpur and Ropar districts. It is used in construction and road building.
Minor Minerals:
Punjab also has a variety of minor minerals, including:
Building Material: Sand, gravel, and stone are extensively quarried for use in construction.
Celestite: This mineral, a source of strontium, is found in the Salt Range.
Chalk: Used in the production of cement and lime.
China Clay: Also known as kaolin, it is used in the ceramic industry.
Gypsum: Found in the Salt Range, gypsum is used in the production of plaster and fertilizer.
Rock Salt: Extensive deposits of rock salt are found in the Salt Range, particularly in the Khewra Salt Mine, which is one of the oldest and largest salt mines in the world.
Sulphur: Recovered as a by-product from fertilizer plants.
Distribution of Minerals:
The distribution of minerals in Punjab is not uniform. Most of the mineral resources are concentrated in the Salt Range and its surrounding areas. The northern and central parts of the state, which are primarily alluvial plains, have limited mineral deposits.
Mineral-Based Industries:
The presence of these mineral resources has led to the development of several mineral-based industries in Punjab. These include:
Cement Industry: The availability of limestone and chalk supports the cement industry in the state.
Ceramic Industry: The presence of fire clay and china clay has led to the growth of the ceramic industry.
Glass Industry: Silica sand is used in the production of glass.
Construction Industry: Sand, gravel, and stone are essential raw materials for the construction industry.
Fertilizer Industry: Gypsum and sulphur are used in the production of fertilizers.
Challenges and Future Prospects:
While Punjab has a diverse range of mineral resources, there are some challenges associated with their exploitation:
Limited Reserves: The reserves of some minerals, such as coal and bauxite, are limited.
Environmental Concerns: Mining activities can have negative environmental impacts, such as deforestation, soil erosion, and water pollution.
Illegal Mining: Illegal mining is a problem in some areas, leading to revenue loss and environmental damage.
