A new method for mining lithium that is potentially more eco-friendly could facilitate the extraction of this crucial mineral from Western Canada’s deposits. Companies are advancing towards demonstrating the viability of the technology on a larger scale.
Lithium found in underground saline water, known as lithium brines, has been challenging to access using traditional methods. However, with the introduction of direct lithium extraction (DLE) technology, companies may now be able to efficiently mine these resources with potentially reduced environmental impact.
One company, LithiumBank, is particularly interested in Alberta due to its existing infrastructure from oil and gas extraction. Leveraging this infrastructure, they aim to develop lithium resources in the province, holding licenses for two projects located northwest of Edmonton.
Unlike traditional methods used in Australia and evaporative extraction in South America, DLE methods involve chemical extraction of lithium from brines, eliminating the need for solar evaporation. This technology opens up new possibilities for lithium production in regions like Canada where traditional methods are not suitable.
With increasing global demand projected to reach 1.3 million tonnes by 2040, lithium is essential for electric vehicle batteries and renewable energy storage. Compared to other extraction methods, DLE is considered more environmentally friendly, especially when powered by clean energy sources like solar.
While DLE may have high energy emissions during extraction and processing, the use of renewable energy can mitigate this impact. DLE also offers water-saving benefits as most of the extracted water can be returned to the ground. Overall, the development of DLE technology could revolutionize lithium extraction and contribute to a more sustainable approach in meeting the rising demand for this critical mineral.
