The majority of lithium is extracted from lithium found in dry lakebeds called salars – largely in the ‘Lithium Triangle’ area of Chile, Bolivia and Argentina. The brine is pumped into a solar evaporation pond for as much as 24 months, when it is transported to a filtering plant where magnesium and boron can be removed to create high purity lithium.
If high levels of magnesium are found in the lithium brine, it makes it a Herculean task to separate the elements form each other because their ions are so similar.
That is, up until now. MGX Minerals (XMG:CNX)(MGXMF) announced a breakthrough in ingredient removal from lithium brine this week, solving the industry’s nagging and complicated magnesium problem.
