- Statement 1: Correct. Extracting one ton of lithium demands about 500,000 liters of water, which can lead to significant depletion of water resources in arid areas, adversely affecting local communities and ecosystems.
- Statement 2: Correct. The Atacama salt flat in Chile is indeed sinking at a rate of 1 to 2 cm annually due to the extraction of lithium brine, which involves pumping salt-rich water to the surface and using evaporation ponds to recover lithium.
- Statement 3: Incorrect. Lithium mining, particularly from hard rock sources, is energy-intensive and requires substantial electricity for processes like crushing, grinding, and chemical separation. This energy often derives from non-renewable sources, increasing carbon emissions and the overall carbon footprint of lithium production.
Thus, the correct statements are 1 and 2, making Option B the correct answer.

Analysis of Statements on Lithium Mining
Lithium mining has garnered attention due to its environmental implications. Let's break down the three statements to understand their validity.
Statement 1: Water Usage
- Extracting one ton of lithium requires approximately 500,000 liters of water.
- This statement is correct. Lithium extraction, particularly from brine sources, is water-intensive. The process often leads to significant depletion of local water resources, which can affect surrounding ecosystems and communities.
Statement 2: Land Subsidence
- The Atacama salt flat in Chile is sinking at a rate of 1 to 2 cm annually due to the extraction of lithium brine.
- This statement is also correct. The over-extraction of lithium brine has led to land subsidence in this region, affecting both the environment and local agriculture. The salt flat is a critical habitat and its degradation poses ecological risks.
Statement 3: Carbon Footprint of Hard Rock Mining
- Lithium mining from hard rock sources has a negligible carbon footprint.
- This statement is incorrect. While hard rock mining might have a lower water footprint compared to brine extraction, it is not devoid of environmental impact. The processes involved in hard rock mining, such as blasting and transporting materials, contribute to significant carbon emissions.
Conclusion
Based on the analysis, the correct answer is b) 1 and 2 Only. Statements 1 and 2 accurately reflect the environmental challenges associated with lithium mining, while statement 3 misrepresents the carbon footprint of hard rock lithium extraction.
