This Arkansas Town Could Become the Epicenter of a U.S. Lithium Boom (msn.com) 53

Posted by EditorDavid from the towns-called-Hope dept.
"If the U.S. is to ease its dependence for lithium on other countries such as China, it may need this quiet corner of southwest Arkansas to lead the way," reports the Wall Street Journal, visiting the "thick-wooded back roads" and "crisscrossing fields where oil drillers gave up long ago" in Magnolia, Arkansas. (Population: 11,105) Exxon Mobil, a new player in the hunt for U.S. lithium, is planning to build one of the world's largest lithium processing facilities not far from Magnolia, with a capacity to produce 75,000 to 100,000 metric tons of lithium a year, according to people familiar with the matter.

The Wall Street Journal reported in May that Exxon purchased 120,000 gross acres in the area for a price tag of more than $100 million. A consultant for the seller had estimated the prospect could have the equivalent of 4 million tons of lithium carbonate equivalent, enough to power 50 million EVs... To push the project forward, Exxon will have to profitably scale up the technology used to siphon lithium from brine, which for years has been an elusive goal across the industry... Exxon believes it can leverage its engineering prowess to become a low-cost domestic supplier of lithium, and has had discussions with battery and EV manufacturers, people familiar with the matter said. The company would also benefit from green-energy subsidies included in the Inflation Reduction Act, which allows for tax credits of 10% of the cost of producing lithium.

Exxon, which is generally bullish about the future of oil and natural gas, is also preparing for a future less dependent on gasoline. Last year, it projected light-duty vehicle demand for internal combustion engine fuels could peak by 2025, while EVs, hybrids and vehicles powered by fuel cells could grow to more than 50% of new car sales by 2050.
"Other companies including Standard Lithium and Tetra Technologies are planning to build capacity in the area..."

      They're going to pump brine out of the ground - I believe by pumping vast quantities of fresh water in first - and then let it evaporate so they can collect the sludge. It should have more that's worth extracting than just lithium.

      I guess the real question is what are they going to do with all the stuff that gets concentrated in the evaporation process that isn't worth separating and selling? And the secondary question would be where they're going to get all the required water and what will be the environmental impact of that?

      I'm crazy but I believe answering those questions to the satisfaction of the EPA and the population ought to be a prerequisite to allowing the operation to proceed. Leaving big ponds of toxic sludge should not be considered an acceptable option.

          Why would you be pumping in freshwater and diluting your brine? That makes zero sense. Deep groundwater is generally already highly pressurized, and if it's not, that's what pumps are for.

          This isn't enhanced oil recovery, where you've already taken out most of what's in a reservoir and are adding in a substance which is non-miscable with your target product to get the rest of it.

        • No, the brine is already rich in BROMINE, which is what they get out of it now, and also happens to have some amount of lithium. All you do is drill down 8000 feet and let the water flow. Dealing with brine is part and parcel for the oil industry, you get salty brine from oil wells all the time. In this case, there was little or no oil but bromine is valuable. And now, lithium is "valuable enough" that someone wants to try to recover it as well.

          • OK, so where will all that bromine-rich water go?

            • They will probably extract the bromine, which is valuable, and then inject whatever is left back into the ground in a different part of the formation.

            And of course, since you're doing selective progressive deposition, you can largely separate them out in the process anyway.

    Mine it with some reasonable care for the environment, process it, make the end product and sell it. Vertical integration. It's better for everyone including the investor class, it just takes a little more time and effort.

          I'm not sure why you think refining lithium out of brine is likely to destroy the environment. Of all of the thousand things we dig into the earth to mine, this is one of the easiest and least destructive.

          What's left behind is mostly salt. Even if they didn't collect that and sell it-- in the US we routinely dump millions of tons of salt on the road every winter snowstorm. Even the worst case disposal of the salt wouldn't hold a candle to the environmental effect of even a mild winter storm.

      Did what? Lithium isn't explosive. Lithium metal is flammable, but nobody is producing lithium metal; they're producing lithium carbonate. Just like how sodium metal is flammable but sodium carbonate is just washing soda.

      And for the record, lithium-ion batteries don't contain lithium metal either. What burns is mainly the electrolyte solvent, generally organic carbonates with combustion properties similar to common hydrocarbon solvents, and indeed, to petrol itself.

    • I didn't read the article, but the summary says it's "$1.5 billion" in lithium, which is like not even worth mining. At $40/kg, that's only 37,500 metric tons, or barely 7% of a single year's global production at recent levels. So a very small amount in the grand scheme of things, probably not worth the investment or environmental damage.

        You should have, because if you did you'd know it's $1.5 billion in lithium ore, which after processing would be about $7 billion worth of lithium carbonate.

    That was my first question. Unsurprising, if you look at the username.

    Geological sources of lithium come in two types - spodumene as a component of granites, and in evaporite brines. If you're talking about mining the granite, you might get a couple of percent yield (and be glad for that) for the tonnage of material you have to dig up, sort, and move. (The actual mineral is about 3.6% Li by mass, but you're going to have to carve away tonnes of non-profitable "gangue" along with the (literal - this iw where the phrase comes from) "pay dirt". The best mine in the world has a 2.4% run-of mine percentage. The other source is lithium rich brines pre-concentrated in evaporite deposits - crystallised-out seawater, or in the case of the Atacama, rainfall evaporated in a desert. I can't find any figures for the typical concentration of lithium in such salts.

    The first stage in isolating lithium from a spodumene resource will typically be roasting the ore (at about 3% w/w Li) to a bright red heat, then extracting it with acid. That's going to produce a lot of nasty waste, whichever way you cut it. The resultant liquor will be a bit "dirtier" than what you'd get out of your "lithium brine", and processing would continue fairly similarly.

    This being in America, I don't believe that the 97% by mass production of finely-crushed acid-soaked rock dust would be easy to get past even the emasculated EPA of today, so it was a safe bet that they'd be looking to process brines. It seems that these brines are in sub-surface salt deposits - which are a common play for hydrocarbon discoveries too. I'd be astonished if Exxon didn't have significant prior art in oil exploration in this area. Possibly over a century of prior art. Hell, in my home country, I could draw a map of prospective areas for this sort of mining on the back of a beer mat, then head off to the Geological Survey to pull the appropriate public records without any expenditure. Exxon's library access and deals with other oil companies in the area will give them pretty good figures to have made that 0.1G$ investment on.

    • This particular location would be brine. Specifically, there are existing oil and gas wells in the region that have been expended, and there are currently activities pumping brine from these wells to extract bromine. Under consideration here is to also extract the lithium from that brine, now that market prices make it economical to do so.

      The process they use for the bromine extraction returns the brine into the (existing) wells so they aren't relying on evaporation pools either.

      • Yeah, as an oilfield geologist, I was interested in the "extraction from primary rock" option. Brine treatment form a salt dome ... Yawn. Drilled a dozen, drilled around the margins of more.

    I am seeing many, many completely misinformed comments.

    This area, Magnolia, Arkansas, has been producing bromine from these natural brines for many decades, and is currently one of the largest bromine producers in the world. The brine also happens to be sort of lithium-rich, but until recently no one wanted the lithium bad enough to try and recover it, so it was just part of the byproduct wastes. Recovery has been tried before and no one could do it and be profitable.

  • Everyone always talks about China, but opening a new mine in the US will not do anything to decrease their hold on the lithium supply.

    This is because less than 15% of the world's lithium supply comes from China. What China has is all of the refining and processing infrastructure. 60% of all lithium is refined there.

    New mines are great and necessary, but if you want to stick it to China, build refineries. You can import lithium ores or salts from Australia (the #1 producer of lithium - about 47%) or Chile (#
