I well waste some time to show you thast link. I am bussy today but I promiss you I will find it.
That dow sorbent is Burbas old sorbent.
In a recent press release, Universidad de Santiago de Chile stated that your technology is the “only one capable of separating lithium without leaving a significant impact on the environment.” Walk us through what differentiates your approach.
When you look at lithium extraction, one hears a lot about direct lithium extraction (DLE), and many start-up companies preach that as if it’s some new thing. The DLE concept actually began at Dow Chemical in the late 1970s and the 1980s, so that idea has been around for a long time.
Basically, it is about having a technology that can selectively pull lithium from the brine and let everything else go by. We are using a proven form of direct lithium extraction that is based on an absorbent that a friend of mine and I invented back in the 1990s. We have improved it since then, but it was groundbreaking at the time.
This material will selectively recover lithium from a saturated brine. And the selectivity is astronomically high.
The reason that matters is because there is not that much lithium in even the best resources. In that Atacama brine that everybody loves, you have about 2,000 parts per million lithium. If you look at Alberta, you are talking about 50 to 80 parts per million.
The lithium concentrations are low and you have to have something that will pick up the lithium and leave behind everything else.
We have improved our process so that – and we still have to prove this – but we are expecting to see recovery rates substantially higher than 60%. And we are hoping for recovery rates in the range of 90% to 95%.
