Lithium Deposits Estimated up to 1600 Tonnes Found in Karnataka

According to AMD (Atomic Minerals Directorate for Exploration and Research), lithium deposits have been found in the Marlagalla area of Mandya district of Karnataka. The announcement for it was made in a written reply to an unstarred question in Rajya Sabha. Union Minister Dr. Jitendra Singh, who holds the portfolio of Science and Technology and Earth Sciences, made this announcement on Friday. He also highlighted that AMD is exploring several other areas in India for lithium deposits.Meanwhile, AMD is carrying out exploration for lithium in the potential geological domains in parts of Korba District, Chhattisgarh. However, the major mica belts located in Rajasthan, Bihar, and Andhra Pradesh and Pegmatite Belts in Odisha, Chhattisgarh, and Karnataka are the potential geological domains in the country for lithium resources.

According to the Royal Society of Chemistry, “Lithium does not occur as the metal in nature, but is found combined in small amounts in nearly all igneous rocks and in the waters of many mineral springs. Spodumene, petalite, lepidolite, and amblygonite are the more important minerals containing lithium. Most lithium is currently produced in Chile, from brines that yield lithium carbonate when treated with sodium carbonate. The metal is produced by the electrolysis of molten lithium chloride and potassium chloride. The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras, and electric vehicles. Lithium is also used in some non-rechargeable batteries for things like heart pacemakers, toys, and clocks. Lithium metal is made into alloys with aluminum and magnesium, improving their strength and making them lighter. A magnesium-lithium alloy is used for armor plating. Aluminum-lithium alloys are used in aircraft, bicycle frames, and high-speed trains.”
In the meantime, AMD’s preliminary survey in Himachal Pradesh has led to the identification of surface mineral occurrences in Masanbal, Hamirpur district, but as per the government, they are not considering establishing any atomic energy plant in Himachal Pradesh. However, they also said that they are in talks with the Russian Federation for expanding cooperation in the peaceful use of nuclear energy, including in the field of small modular reactors.
