Mineral Resources and Extraction in India

India is rich in various mineral resources, and the extraction of these minerals is concentrated in different states depending on their geological distribution. The question asks about the state that is a major producer of both gypsum and silver ore.

Gypsum Production in India

Gypsum is a soft sulfate mineral primarily used as a fertilizer and as the main constituent in many forms of plaster, drywall, or sheetrock. India is among the leading producers of gypsum globally.

Key facts about gypsum extraction in India:

• A significant majority of India's gypsum production comes from one state.
• This state has vast reserves of high-quality gypsum.
• Gypsum is crucial for agriculture (improving soil structure) and the construction industry.

Silver Ore Extraction in India

Silver is a precious metal often found in ores along with other metals like lead, zinc, copper, and gold. While not as abundant as some other minerals, silver extraction is economically important.

Important points regarding silver ore in India:

• Silver extraction often occurs as a byproduct of mining other base metals.
• India has limited primary silver mines, with most production linked to lead-zinc or copper mining.
• Despite this, one state accounts for a major share of the nation's silver production.

Identifying the Major Producing State

Let's consider the options provided and their prominence in the production of gypsum and silver ore:

• Bihar: Known for minerals like mica (historically), iron ore, and bauxite, but not significantly for gypsum or silver ore.
• Rajasthan: This state is famously rich in a wide variety of minerals, including lead, zinc, copper, and also hosts significant deposits of non-metallic minerals like gypsum. It is the dominant producer of both gypsum and zinc-lead ore (from which silver is often extracted as a byproduct).
• Jharkhand: A leading producer of coal, iron ore, bauxite, mica, and copper, but not primarily known for major gypsum or silver extraction.
• Odisha: A major hub for iron ore, bauxite, chrome ore, and manganese ore, but not a significant producer of gypsum or silver ore.

Based on mineral distribution and extraction data, Rajasthan is overwhelmingly the leading state in India for the production of gypsum. It also contributes the largest share to India's silver production, primarily derived from the mining of lead-zinc ores in the state.

Conclusion on Major Extraction Area

Considering both gypsum and silver ore extraction, the state that accounts for a major part of their production in India is Rajasthan.

Additional Information: Mineral Belts of India

India's mineral resources are concentrated in specific belts:

• North-Eastern Plateau Region: Covers Chota Nagpur Plateau (Jharkhand, West Bengal, Odisha, Chhattisgarh). Rich in coal, iron ore, bauxite, mica.
• South-Western Plateau Region: Extends over Karnataka, Goa, Tamil Nadu uplands, and Kerala. Rich in ferrous metals (iron ore, manganese), bauxite, and limited coal. Lacks in mineral fuels.
• North-Western Region: Covers Rajasthan and parts of Gujarat. Rich in copper, zinc, gypsum, silver, lead, mica, and rock salt. Also known for building stones. The Himalayas also have mineral deposits but are largely inaccessible.

The North-Western region, particularly Rajasthan, is prominent for non-ferrous metals and non-metallic minerals like gypsum, aligning with its significant extraction of both gypsum and silver ore.
