The Nice Salt Lake isn’t an apparent place to develop a lithium mine. The Salton Sea boasts lithium concentrations of just below 200 components per million. Argentina, the place Lilac has one other check facility, has sources of above 700 components per million.
Right here on the Nice Salt Lake? “It’s 70 components per million,” Raef Sully, Lilac’s Australia-born chief govt, tells me. “So should you had a soccer stadium with 45,000 seats, this could be three folks.”
For Lilac, that is truly a characteristic of the situation. “It’s a really, excellent demonstration of the aptitude of our expertise,” Sully says. Displaying that Lilac’s {hardware} can extract lithium at excessive purity ranges from a brine with low focus, he says, proves its versatility. That wasn’t the explanation Lilac chosen the positioning, although. “Utah is a mining pleasant state,” says Elizabeth Pond, the vice chairman of communications. And although the lake water has low concentrations of lithium, extracting the brine merely requires working a hose into the water, whereas different areas would require digging a properly at nice price.
Once I accompanied Sully to the check website throughout my tour, our route following unpaved county roads lined with fields of untamed sunflowers. The ability itself is little greater than an assortment of transformed transport containers and two cellular trailers, one to function the primary workplace and the opposite as a subject laboratory to check samples. It’s off the grid, counting on diesel turbines that the corporate says will likely be changed with propane items as soon as this location is transformed to a everlasting facility however may finally be swapped for geothermal expertise tapping right into a scorching rock useful resource positioned close by. (Photo voltaic panels, Sully clarifies, couldn’t provide the 24-7 energy provide the power will want.) But it surely depends upon its connection to the Nice Salt Lake through that prolonged hose.

Pumped uphill, the lake water passes by way of a collection of filters to take away solids till it leads to a vessel stuffed with the corporate’s specifically designed ceramic beads, constituted of a patented materials that draws lithium ions from the water. As soon as saturated, the beads are put by way of an acid wash to take away the lithium. The remaining brine is then repeatedly examined and, as soon as deemed secure to launch again into the lake, pumped again all the way down to the shore by way of an outgoing tube within the hose. The lithium resolution, in the meantime, is stockpiled in tanks on website earlier than transport off to a processing plant to be become battery-grade lithium carbonate, which is a white powder.
“As a expertise supplier in the long run, if we’re going to have many years of lithium demand, they need to place their expertise as one thing that may faucet a bunch of markets,” McBride says. “To have a expertise that may doubtlessly economically get better various kinds of sources in various kinds of environments is an attractive proposition.”
This testing floor received’t keep this manner for lengthy. Throughout my go to, Lilac’s crew was beginning to pack up the situation after finishing its demonstration testing. The outcomes the corporate shared completely with me counsel a smashing success, notably for such low-grade brine with quite a few impurities: Lilac’s gear recovered 87% of the out there lithium, on common, with a purity price of 99.97%.
