LITHIUM RESERVES FOUND IN MARLAGALLA-ALLAPATNA REGION OF KARNATAKA'S MANDYA DISTRICT
Alongside a move to tap into the global lithium value chain, India has initiated a concerted domestic exploration push for the alkali metal lithium, a vital ingredient of the lithium-ion rechargeable batteries that power electric vehicles (EVs), laptops and mobile phones.
Preliminary surveys by the Atomic Minerals Directorate for Exploration and Research (AMD), an arm of the Department of Atomic Energy, have shown the presence of 1,600 tonnes of lithium resources in the igneous rocks of the Marlagalla-Allapatna region of Karnataka’s Mandya district.
It could boost local manufacturing of EV batteries.
But, India's lithium find is small compared to many major producers, in comparison with 8.6 million tonnes of Chile, 2.8 million tonnes of Australia, 1.7 million tonnes of Argentina or 60,000 tonnes of Portugal.
NOT ENOUGH EXPLORATION EFFORTS
India currently imports all its lithium needs.
The imports of lithium batteries tripled to $1.2 billion in fiscal year 2019 from $384 million in FY17.
Experts say while India requires lithium for its energy needs, there has been no comprehensive effort to map local reserves of lithium so far.
So far, in the absence of local mines for lithium, India has set up Khanij Bidesh India Ltd. to source and acquire mines in Argentina, Bolivia and Chile.
Niti Aayog has set an ambitious goal of building up to 10 large factories to produce lithium-ion batteries over the next 10 years.
THE WHITE GOLD RUSH - "LITHIUM TRIANGLE" overlying Chile, Bolivia and Argentina
Lithium is mined from Jujuy Province of Argentina.
LITHIUM - LARGEST RESERVES
BOLIVIA has massive lithium deposits, which account for 60% of the world’s reserves.
Estimates indicate that the world’s largest deposits of Lithium occur in the Salar de Uyuni salt flats of Bolivia.
Some studies indicate that Salar de Uyuni has 140 Million tonnes of Lithium.

WHERE DOES LITHIUM ACTUALLY COME FROM AND HOW IS IT OBTAINED ?
There are two main sources of lithium:
1) Brine Water
2) Traditional Mines
LITHIUM FROM BRINE WATER
Most of the world’s lithium (87%) comes from brine water.
Among brine water sources, briny lakes known as "salars" offer the highest concentration of lithium as much as 1,000 to 3,000 parts per million.
The salars with the highest lithium concentrations are located in Bolivia, Argentina and Chile.
Lithium obtained from salars is recovered in the form of lithium carbonate, the raw material used in lithium ion batteries.
The production process is fairly straightforward and requires only natural evaporation, which leaves behind lithium along with magnesium, calcium, sodium and potassium.
LITHIUM FROM MINES
The remaining 13% of the world’s lithium is found in traditional mines.
Lithium concentrations in pegmatites of hard-rocks are higher than those found in brine, but the mining process has a higher cost and a larger environmental footprint.
Still, hard-rock lithium mining can be competitive, at least in mines that are already in operation.
Over 145 minerals contain lithium, but only five (spodumene, lepidolite, petalite, amblygonite, and eucryptite) are utilized in lithium extraction.
Of those five, spodumene provides the largest proportion of all mineral-derived lithium.
RECYCLED LITHIUM
The smallest currently available source of lithium is that contained in recycled electronics.
While lithium recycling is not yet capable of yielding lithium pure enough for reuse in batteries.
But it can be used in glass and ceramics, the second-largest lithium-consuming industry after the lithium ion battery industry.
But lithium recycling remains a niche market and only one recycling facility for lithium ion batteries exists in the U.S.
