Hopefully it isn't very expensive, otherwise companies won't adopt it voluntarily

Aspiring’s pilot plant, which opened in February, is in an anonymous industrial estate east of the city. One corner of the main floor is dominated by a large stainless-steel tank, which is connected to a series of smaller tanks arranged in a stepped line. “Apart from our electrolysis system, the hardware is more typical of dairy plants,” says Colum Rice, Aspiring’s chief commercial officer. “The process is elegant but not massively complicated. Our inputs are rock, water, and renewable energy, and our products come with no CO2 emissions.”

Danczyk explains that at the end of the extraction process, they’re left only with a salty brine. “This goes to an electrolyzer, which recycles and regenerates the acid we use for digestion and the base we use to separate the products. It’s a closed loop. We’re using the whole rock, and we’re processing it at low temperature and ambient pressure.”

This sounds great, but scaling electrolysis would require shedloads of renewable energy.

Is this just the precipitation method? The one that's used by like 70% of all manufacturers? And they want to use waste olivines with 10% yield?

They're about to get an expensive lesson in throughout economics.

Also, are they trying to get HCl from salt solution via electrolysis? I didn't know that was possible. Sodium is some 3 volts, you'd dry up all the water before getting to sodium. I'm probably missing something here.

Handwaving away electrolysis as being from renewable energy and the fact that 50 percent of their product is silica that could be used for "Portland cement", lol. As far as where you get the clinker for that Portland, well who knows.

I mean yeah, you can do a lot with electrolysis if you've got unlimited free energy. I don't know what sane person is doing it to recover sulfuric acid of all things from brine.
