Petrolithium is a new approach that focuses on concentrating lithium and other elements from abundantly available wastewater (brine) that accompanies oil and gas production.

Long known to contain valuable elements, wastewater brine is plentiful, yet currently treated as a waste product that is either injected deep underground or stored in giant tanks after it is separated from oil.


  • Ability to utilize existing O&G infrastructure
  • Cleans brine while separating valuable minerals
  • Allows for scalable capital deployment
  • Simplifies permitting process
  • Eliminates solar evaporation step

MGX has developed a proprietary, low-energy design process that is patent-pending. The process rapidly concentrates lithium and other elements from brine.

MGX has successfully concentrated lithium from heavy oil evaporator blowdown wastewater using its rapid recovery process. The process has also been independently confirmed by the Saskatchewan Research Council.

The technology was chosen as winner of the Base and Specialty Metals Industry Leadership Award at the 2018 S&P Global Platts Global Metals Awards. Hosted by S&P Global Platts, a leading global energy, metals and commodities information provider, the annual awards program honored exemplary performance in fifteen categories spanning the entire steel, metals and mining complex.

MGX and its engineering partner have fabricated skid-mounted, commercial-scale lithium extraction units for deployment into oilfields. The units integrate with existing oil and gas infrastructure and are specifically designed for highly-mineralized brine associated with oilfields.
