Strategic minerals are minerals which countries deem to be particularly important for various reasons - it could be for energy needs, for exports or for defense or high tech industry. What makes a mineral strategic can change over time. Arguably, coal was an important strategic mineral during the industrial revolution and during the steamship era. Before it was replaced by oil, navies had to have coal bunkering facilities to fuel their warships. Today, however, although coal is still very important in countries like India and China where it fuels large numbers of coal fired power stations, it is far less important in most European countries because of the shift towards oil and gas and nuclear energy. But in the modern world, with the threat of climate change, and the shift towards an increasingly electrified and digital economy, the minerals which are increasingly important are copper, lithium, cobalt and various rare earths, used for mobile phones, power cables, electric car batteries and the like. And the important issue is that, like oil and gas, they are not equally geographically distributed. Korea and Japan for example have very little in the way of oil and gas. Copper, which used to be mined in the Mediterranean, is now of immense importance because of its high electrical conductivity. Deposits are concentrated in the central African copper belt which straddles Zambia and Democratic Republic of Congo and particularly in Chile and Rio Tinto Zinc also has a mine in Mongolia. The developed worth is now increasingly dependent on copper. Lithium is found in various places but the world's largest deposits are found in the intermontane basins of what is called the Lithium triangle spanning Argentina, Bolivia and Chile. Cobalt deposits are again concentrated in the Democratic republic of Congo, and are characterized by informal, artisanal, and often illegal mining. The rare earth minerals are found in various countries but 80% of the processing is concentrated in China. So, in all of these examples, geography is extremely important in terms of both the distribution of resources, access and ease of extraction. The geography of strategic minerals is likely to become more important in the future.
