World — Minerals, industries & resource distribution

World mineral and industrial geography asks why a resource is found in one place, processed in another, and consumed in a third. For UPSC, the topic is not a list of mines; it is a chain from geology to markets, technology, law and environmental limits.

• Resource, reserve and ore: a resource is known or inferred natural material with possible value; a reserve is the economically recoverable part under present prices, technology and law; ore is a mineral-bearing rock from which extraction is worthwhile. This distinction explains why Bolivia may have huge lithium resources while Australia leads hard-rock lithium output.
• Mineral classification: metallic minerals include iron ore, copper, bauxite, manganese, nickel, cobalt and rare earth elements; non-metallic minerals include limestone, phosphates, potash, mica and gypsum; fuel minerals include coal, petroleum, natural gas and uranium.
• Resource distribution is uneven: endogenic processes concentrate copper, nickel, platinum group metals and rare earths; sedimentary basins concentrate coal, oil, gas, phosphates and many evaporites; tropical weathering produces bauxite and laterite-hosted nickel.
• Indian constitutional lens: Article 297 vests things of value within territorial waters, the continental shelf and the exclusive economic zone in the Union. Union List entries 53-57 cover oilfields, mineral oil resources, mines and mineral development under Union control, labour safety in mines, and inter-State rivers. State List Entry 23 covers mines and mineral development subject to Union List Entry 54; State List Entry 50 covers taxes on mineral rights subject to Parliament's limits.
• Directive and environmental basis: Article 39(b) asks the State to distribute material resources for the common good; Article 48A directs environmental protection; Article 51A(g) creates a citizen duty to protect the natural environment; Article 21 has been read with environmental quality in several environmental cases.
• Core Indian statutes: the Mines and Minerals (Development and Regulation) Act, 1957 structures reconnaissance, prospecting, exploration, mining leases, auctions, royalty and penalties. The Mines Act, 1952 concerns mine safety. The Environment Protection Act, 1986, Forest Conservation Act, 1980 and environmental-clearance rules determine whether extraction can proceed.
• Recent legal architecture: the 2023 amendment to the 1957 mining law introduced central auctions for specified critical and strategic minerals in Part D of the First Schedule, while the Offshore Areas Mineral (Development and Regulation) Amendment Act, 2023 brought auction-based allocation to offshore mineral blocks.
• Exam trap: geography questions often hide law inside location questions: seabed nodules, offshore hydrocarbons and coastal minerals must be read with Article 297 and maritime zones, not only with physical geography.
