Direct lithium extraction: Balancing sustainability and recovery optimization

Figure 1. The DLE process runs without the need for evaporation ponds, and it returns spent brine back to the aquifer.

This lithium production methodology is growing rapidly, drawing interest from environmentalists and producers alike, because it reduces the environmental impact and the cost of lithium production. by Jorge Espinoza and Victor Mwaba Growing demand for lithium compounds for use in the manufacture of rechargeable batteries is constrained by the difficulty of maximizing its extraction from natural sources. There are only…
