Hard-Rock Mining vs. Brine Extraction

Canada’s lithium mining predominantly focuses on hard-rock deposits, particularly spodumene, which is found in pegmatite formations. This method involves conventional mining techniques: drilling, blasting, and excavating ore from open pits or underground. The extracted ore is then crushed and milled to produce a concentrate, typically containing 6% lithium oxide. This concentrate is then shipped to chemical processing plants, often located in Canada or overseas, for conversion into lithium carbonate or hydroxide. This process is capital-intensive and requires significant infrastructure, but it offers faster production cycles compared to brine extraction. In contrast, brine extraction, common in countries like Chile and Argentina, involves pumping lithium-rich groundwater from underground salt flats into vast surface ponds. Solar evaporation concentrates the lithium salts over a period of 12-24 months. While this method has a lower upfront capital cost and can be more energy-efficient due to reliance on solar evaporation, it is geographically limited to arid regions and can have its own environmental considerations, including water usage and land impact. The choice of extraction method significantly influences a company’s operational costs, production timelines, and environmental footprint.

The transformation of raw lithium ore or brine into battery-grade lithium carbonate or lithium hydroxide is a critical, high-value step in the lithium supply chain. This refining process is where significant investment and technological expertise are concentrated. For spodumene concentrate from Canadian mines, the process typically involves calcination at high temperatures to convert it into a more reactive alpha-spodumene. This is then leached with acids to extract the lithium, followed by purification steps to remove impurities and produce either lithium carbonate or lithium hydroxide. Brine operations, after solar evaporation, yield a lithium chloride concentrate which is then further processed to produce lithium carbonate. This carbonate can be converted to lithium hydroxide through reaction with caustic soda. The purity requirements for battery-grade materials are exceptionally stringent; even trace impurities can negatively impact battery performance, lifespan, and safety. Therefore, big lithium mining companies are investing heavily in advanced chemical processing and quality control measures. Establishing robust refining capabilities within Canada is a key strategic goal, aiming to reduce reliance on overseas processing and capture more value domestically.
