The Nice Salt Lake isn’t an apparent place to develop a lithium mine. The Salton Sea boasts lithium concentrations of just below 200 elements per million. Argentina, the place Lilac has one other take a look at facility, has assets of above 700 elements per million.
Right here on the Nice Salt Lake? “It’s 70 elements per million,” Raef Sully, Lilac’s Australia-born chief govt, tells me. “So when you had a soccer stadium with 45,000 seats, this might be three folks.”
For Lilac, that is truly a function of the situation. “It’s a really, superb demonstration of the potential of our know-how,” Sully says. Exhibiting 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 location, although. “Utah is a mining pleasant state,” says Elizabeth Pond, the vp of communications. And although the lake water has low concentrations of lithium, extracting the brine merely requires operating a hose into the water, whereas different places would require digging a properly at nice value.
After I accompanied Sully to the take a look at website throughout my tour, our route following unpaved county roads lined with fields of untamed sunflowers. The power itself is little greater than an assortment of transformed transport containers and two cellular trailers, one to function the principle workplace and the opposite as a area laboratory to check samples. It’s off the grid, counting on diesel mills that the corporate says can be changed with propane items as soon as this location is transformed to a everlasting facility however might finally be swapped for geothermal know-how tapping right into a sizzling rock useful resource positioned close by. (Photo voltaic panels, Sully clarifies, couldn’t provide the 24-7 energy provide the ability will want.) However it will depend on its connection to the Nice Salt Lake by way of 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, produced from a patented materials that pulls 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 protected 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 answer, in the meantime, is stockpiled in tanks on website earlier than transport off to a processing plant to be became battery-grade lithium carbonate, which is a white powder.
“As a know-how supplier in the long run, if we’re going to have many years of lithium demand, they need to place their know-how as one thing that may faucet a bunch of markets,” McBride says. “To have a know-how that may doubtlessly economically get better several types of assets in several types of environments is an attractive proposition.”
This testing floor received’t keep this fashion 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 solely with me recommend a smashing success, notably for such low-grade brine with quite a few impurities: Lilac’s tools recovered 87% of the accessible lithium, on common, with a purity price of 99.97%.
