Lithium is produced from a variety of geological sources, e.g., minerals such as spodumene, clays such as hectorite, salt lakes, and underground brine reservoirs etc. In order to simplify, two broad categories of lithium sources will be defined and used throughout the paper, namely rock and brine sources. Rock sources will cover lithium contained in rocks; specifically, Rock sources include mineral sources such as spodumene, amblygonite, jadarite, as well as clay sources of lithium such as hectorite. Typical mineral deposits have a lithium content of around 0.5%–2% Li. Often the lithium from minerals is concentrated to around 2%–4% Li and used in the ceramics and glass industry. Lithium rock production began with lithium minerals back in 1899 in the USA. Lithium is also referred to as ‘white gold’. With the impending advent of the widespread use of electric cars, trucks plus the millions of rechargeable consumer electronic devices that utilize lithium-ion batteries, it is no wonder that numerous exploration companies have turned their attention to the vast Lithium Triangle in Argentina, Chile and Bolivia. It has been estimated that South America’s Lithium Triangle hosts about 54% of the world’s lithium resources. Africa accounts for less than five per cent of the total Lithium reserves. There are two sources of lithium – hard rock (the mineral spodumene) and lithium brine that formed in desert climates where there is a slow inflow of lithium and other metals and salts but no outflow. Gradual evaporation over thousands of years slowly increases lithium grades to an economic level. Top three lithium-producing countries in the world in 2019-20 are Australia (1st, which produced 42,000 tonnes), Chile (which produced18,000 tonnes) and China (3rd, produced 7,500 tonnes). Recently, India has also show interests in investing in this region and India and Bolivia are in talks about having a joint manufacturing base for the batteries, both Chile and Argentina are in talks about exploration and exports of Lithium. The government has formed `KABIL’ consortium which has three state-owned companies: National Aluminum Company (NALCO), Hindustan Copper (HCL) and Mineral Exploration Corp Ltd., (MECL). It has been set up to help in the process of acquiring this most strategic mineral globally. 1 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Cancel the best answer Leave an answerCancel replyYou must login or register to add a new answer.
