AXIONIT® Technology

The traditional method of obtaining lithium from hydromineral raw materials is evaporating water in open-air ponds under the sun over an area of tens of square kilometers. This process takes several months to 1.5 years and requires substantial investment.

An alternative to this method is AXIONIT® sorption.
The technology is 2-3 times more economical than the traditional one and allows to extract lithium with concentrations from 5 mg/L directly.

Advantages of AXIONIT® Technology

up to 99% lithium extraction efficiency from hydromineral raw materials

extraction process duration of up to 1 day

sorbent capacity for lithium of up to 4-6 kg/m3

environmentally friendly process
due to the use of water for desorption

applicable in any climate, no dependence on weather conditions

We are Russia’s leading company dealing in lithium extraction.

Our lithium extraction plant in Argentina produces 100 tons of lithium carbonate equivalent a year.
