Lithium, an essential element in nature, has recently been discovered as a high-grade resource in Nigeria. The exciting find follows the reputation of Greenbushes mine in Western Australia, known as the world’s largest hard-rock Lithium mine. Countries like South Korea, China, Japan, US, and Belgium rank as the largest importers of lithium, with their demand ever-increasing.
Understanding the Composition of Lithium
Lithium specializes in two minerals, spodumene and lepidolite, usually found in unique rocks named rareCand greisens. The element is described as high grade when it contains 1-13% oxide content, a notable increase from conventional exploration levels of 0.4%. The grade percentage offers a measure of lithium concentration in minerals or rocks, where a higher grade indicates greater economic viability. Such high grades are a rarity for metals like lithium.
The Various Applications of Lithium
The strength, machinability, and translucency of the chemical compound Lithium disilicate (Li2Si2O5) make it a widely preferred material for dental ceramics. Lithium’s adaptability extends to alloy making, forging crucial parts in motor engines, aircraft, and armor plates. Additionally, lithium plays a significant role in powering rechargeable batteries for mobile phones, laptops, digital cameras, and electric vehicles. Some non-rechargeable batteries also use lithium for devices like heart pacemakers, toys, and clocks.
Different lithium-based batteries include Lithium-cobalt oxide, Lithium-nickel-manganese-cobalt, and Lithium iron phosphate, among others. Each type offers unique performance levels, cost-effectiveness, safety, and popularity, with particular attention given to clean energy applications.
Lithium’s Rising Demand for Clean Energy
As more countries outline plans for phasing out fossil fuels in favor of zero-emission electric vehicles, the demand for lithium intensifies. In less than a decade, from 2010 to 2019, lithium production increased globally from 28,100 metric tonnes to 86,000. The pressing challenge lies in sufficiently supplying the market with lithium.
Lithium Reserves in India
India’s Atomic Minerals Directorate researchers have announced lithium reserves estimate of 14,100 tonnes on a small land patch in Southern Karnataka’s Mandya district. This discovery marks India’s first ever Lithium deposit site.
India’s Pursuit to Reduce Lithium Imports
To promote local electric vehicle (EV) industry growth and decrease its reliance on imported lithium, India has embraced a multi-modal strategy. State-run Khanij Bidesh India Ltd collaborates with authorities in Argentina, Chile, Australia, and Bolivia – countries known for their rich lithium reserves – to secure overseas lithium and cobalt mines. Furthermore, India is exploring urban mining to keep recycled materials in circulation, reducing the need for fresh lithium inputs and consequently, the import requirements.
Trivia: Comparison of Metals’ Weight
An interesting comparison reveals lithium as the lightest known metal, while osmium holds the title for the heaviest. Light metals are characterized by low atomic weight, whereas heavy elements typically have high atomic weight. Osmium, with an atomic number of 76 and an atomic weight of 190.2 u, boasts the greatest density of all known elements. Lithium, however, is lightweight with an atomic number of 3 and an atomic weight of 6.941u.
