Buying Lithium In Bolivia: A Comprehensive Guide

Bolivia is home to Salar de Uyuni, the world's largest salt flat, which contains massive lithium deposits—about 50% of the earth's total. The global demand for lithium has surged due to its use in electric vehicles and electronic devices, and Bolivia views its lithium reserves as a transformative opportunity for industrialization. However, extracting lithium requires substantial amounts of water, and the current methods used in neighbouring countries may not be well-suited to the conditions in Bolivia. As a result, Bolivia has sought partnerships with foreign companies to develop new extraction technologies. While there have been concerns about the potential environmental impact of lithium mining and the distribution of benefits to local communities, the successful development of Bolivia's lithium industry could significantly boost its economy.

Bolivia's lithium reserves

Bolivia is home to the world's largest lithium deposits, constituting 50% of the earth's total. The country's lithium reserves are estimated at 23 million metric tons, with the Salar de Uyuni salt flat in Bolivia containing massive lithium deposits.

The global demand for lithium has surged since 2010 due to its use in battery production for electric vehicles and electronic devices. Bolivia views its lithium resources as a transformative opportunity for industrialization and modernization. The country aims to position itself as a global leader in lithium production and the development of new lithium batteries.

However, there are concerns about the environmental and social impacts of lithium extraction. The process requires substantial amounts of water, which could be a challenge for a country like Bolivia, which has a history of social instability due to water scarcity. Additionally, there are concerns about the potential for socioeconomic exclusion and the reinforcement of an extractive model with limited local development.

To address these challenges, the United States has an opportunity to help Bolivia develop its lithium reserves sustainably and productively. The Department of Energy can partner with Bolivian counterparts for academic exchanges, joint research, and development of more efficient and environmentally friendly lithium production methods.

Extraction methods

The majority of commercial lithium extraction occurs in the "Lithium Triangle" of Bolivia, Argentina, and Chile, as well as China. The lithium is extracted from underground brine reservoirs (salars) beneath salt flats. This conventional lithium brine extraction method is a straightforward but time-consuming process. Here is a step-by-step guide:

• Salt-rich water is pumped from the underground reservoirs to the surface and into evaporation ponds.
• Over several months, the water evaporates, leaving a variety of salts.
• Hydrated lime (Ca(OH)2) is added to the brine to remove unwanted elements, especially magnesium and boron.
• Once the lithium concentration is high enough, the brine is pumped to a recovery facility.
• The brine undergoes purification to remove any remaining contaminants.
• The brine is treated with chemicals to isolate desirable products and by-products through precipitation.
• The brine is filtered to remove the precipitated solids.
• The brine is treated with soda ash (Na2CO3) to produce lithium carbonate (Li2CO3).
• The lithium carbonate is washed and dried, creating the final product.

Other methods of lithium extraction are being explored to increase global production. These include direct lithium extraction from geothermal and oil well brines, as well as mining lithium-bearing clays, seawater, and recycled electronics. However, these methods are not yet economically viable or widely used.

It is important to note that the conventional brine extraction method described above may not be well-suited for Bolivia due to high levels of impurities in the brine and the presence of a rainy season, which lengthens the evaporation process. As a result, Bolivia has shown interest in adopting new "direct lithium extraction" technologies that can extract lithium directly from brine without the need for solar evaporation.

Environmental concerns

The environmental concerns surrounding the extraction of lithium in Bolivia are significant. Firstly, the process requires substantial amounts of water—approximately 500,000 gallons per ton of lithium. This is a major issue in a country with a history of social instability due to water scarcity. The impact of lithium extraction on water supplies is twofold: not only does it contribute to water depletion, but it also poses a risk of water contamination. In Chile, for example, lithium extraction has consumed 65% of the region's water supply, leading to extreme water shortages and negatively impacting local farmers' ability to grow crops and maintain livestock. Similar concerns have been raised in Argentina, where natives of the Salta and Catamarca provinces have accused lithium mining companies of contaminating the streams used for irrigation, human consumption, and livestock.

Bolivia's salt flats, where lithium is extracted, are a fragile ecosystem. The extraction process also harms the soil and contaminates the air. The potential impact on the environment is further exacerbated by the fact that the extraction process is energy-intensive, leading to excessive carbon emissions. This is particularly concerning in a country like Bolivia, which faces high levels of food insecurity and malnutrition and has suffered from multiple droughts and floods in recent years.

The specific extraction method used in Bolivia, brine extraction, requires excessive land and water use. This process is lower in CO2 emissions compared to hard rock mining but has been criticised for its environmental impact. Studies of Chile's successful lithium mining industry, which uses the same extraction method, point towards signs of environmental degradation. There are concerns that the same could happen in Bolivia, with reports already emerging of fish and livestock damage in rural communities.

In response to these concerns, Bolivia's new president, Luis Arce, has made it a national priority to pursue direct lithium extraction (DLE), which can preserve over 98% of the water supply used. This method offers a more sustainable approach to lithium mining in water-scarce areas. However, it is a relatively new technology, and Bolivia currently lacks the technical knowledge, infrastructure, and economic capacity to implement it without foreign investment and cooperation.

Economic impact

Bolivia is home to Salar de Uyuni, the world's largest salt flat, which contains massive lithium deposits—about 50% of the earth's total. The global demand for lithium has surged since 2010, and Bolivia views its lithium resources as a transformative opportunity for industrialization and modernization. However, the country faces significant economic, political, and technical challenges in scaling up lithium production.

Bolivia's plans to extract lithium have faced obstacles due to the high levels of impurities in the brine and the rainy season lasting several months. The typical method of lithium extraction involves pumping brine into ponds and waiting for the water to evaporate, leaving lithium salts behind. This method has been successful in neighboring Chile and Argentina but is less suitable for Bolivia due to the unique characteristics of its brine and climate.

To address these challenges, Bolivia has sought partnerships with foreign companies to develop new "direct lithium extraction" (DLE) technologies. DLE can potentially extract lithium directly from brine without the need for solar evaporation, reducing water usage and weather dependency. However, these technologies are largely unproven at a commercial scale, and Bolivia would need much more investment to make a significant impact in the global market.

The country has signed deals with Chinese, Russian, and German companies to develop its lithium industry. However, these partnerships have faced criticism and protests from local communities, who worry about the environmental impact of lithium mining and demand a greater share of the revenue. There are also concerns about the potential for socioeconomic exclusion and the negative effects of extractive industries on the environment and biodiversity.

If Bolivia can successfully develop its lithium industry, it could significantly boost its economy. The country's GDP could rise from its current level of roughly $40 billion, with the lithium industry potentially adding $5 billion by 2027. However, Bolivia needs to navigate the challenges of managing rapid industry growth, ensuring transparency, and balancing the interests of foreign companies, local communities, and the environment.

Political implications

Bolivia's lithium reserves are largely located in the Salar de Uyuni, the world's largest salt flat. The country's efforts to exploit these reserves have been marked by a struggle between the government's desire for state control and the need for foreign investment and expertise. This dynamic has played out in the country's partnerships with foreign companies and has had political ramifications, including protests and the ousting of former President Evo Morales.

Bolivia's government has long prioritised state control over lithium and other natural resources. This stance was particularly prominent under the government of Evo Morales, who envisioned using the country's lithium resources for industrialization and modernization. However, the reality of developing these resources has proven complex. Bolivia's salt flats have high levels of impurities and a rainy season, making lithium extraction challenging and costly.

In 2018, Bolivia signed a deal with ACISA, a German company, to develop its lithium industry. However, this agreement was met with protests from the Potosí civic committee, an umbrella civil society organisation in the region. The protesters argued that the deal did not offer sufficient economic benefits to the region and demanded higher royalties and a greater allocation of revenue from lithium mining. As a result, Morales cancelled the deal with ACISA, but the protests continued, contributing to his resignation in 2019.

Morales attributed his removal from office to a ""lithium coup," suggesting that foreign interests sought to punish Bolivia for seeking partnerships with Russia and China. However, analysts dispute this claim, noting that the ACISA deal was favourable for the German company and that China already dominates global lithium production.

Following the cancellation of the ACISA deal, Bolivia shifted its strategy and called for proposals from foreign companies to develop new "direct lithium extraction" (DLE) technologies. This process attracted interest from companies in China, Russia, and the United States. The Bolivian government's partnerships with Chinese and Russian companies, in particular, sparked concerns in the United States, with officials worrying about the potential reinforcement of an extractive model with limited local development.

The United States has its own interests in the region and sees an opportunity to strengthen democratic stability and prosperity in Latin America. By leveraging its technical advantages and hemispheric position, the US aims to help Bolivia develop its lithium reserves productively and economically viably. This approach could also edge out competitors like China, whose transactional approach has been criticised.

However, Bolivia's previous attempts to work with foreign companies have been challenging due to the country's desire for state control and the complex dynamics of the global lithium market. As a result, Bolivia's dream of a lithium-powered economy remains uncertain, and the political implications of managing these resources continue to evolve.
