Argentinian lithium producer Orocobre (TSX: ORL) recently reported lower than expected lithium production in its third fiscal quarter because weather interfered with its evaporation rates of its lithium brines. This reveals two problems with lithium brine production: reliability and geography. Another source of lithium is rising to met these problems, hard rock lithium mining.
One analyst pointed out that Orocobre’s production problems “clearly demonstrate” that production is not a straightforward process. “Weather events are beyond the control of Orocobre, but this reaffirms that there is still room to improve on the robustness of operations and reduce production variability from we ather impacts,” the analyst stated.
The company reported a 25-per-cent lower evaporation rate compared with the same quarter in 2017 which caused production problems and lithium output to fall 29 percent to 2,802 tonnes of Lithium Carbonate equivalent, from 3,937 tonnes in the December quarter. Its February rates were the lowest since 2011.
Weather has clear impacts on the production at lithium brine operations and with global demand for lithium on the rise, more reliable and consistent methods of production will be required. Lithium brine operations are limited to select climates and regions that can support sufficient weather to ensure economic processing.
Demand for the metal is set to grow by 600,000-800,000 tonnes of lithium carbonate equivalent over the next 10 years, Daniel Jimenez, senior commercial vice president at SQM, said.
