Readit NewsTo determine how much seawater is needed to obtain 1 gram of lithium, you can set up a proportion:
Given: 1 liter of seawater = 0.17 mg of lithium x liters of seawater = 1,000 mg (1 gram) of lithium
Using cross-multiplication:
x = (1,000 mg * 1 liter) / 0.17 mg x ≈ 5,882.35 liters
Thus, you would need to process approximately 5,882.35 liters (or about 5.88 cubic meters) of seawater to obtain 1 gram of lithium.
In practice, extracting lithium from seawater is more challenging due to its low concentration and the presence of other elements. Techniques have been proposed and researched, but as of my last update in 2021, they were not commercially competitive with other sources of lithium like mineral deposits.

We definitely want HN to credit the original sources and (even more so) researchers but I'm not sure what the best move here would be, or whether we need to change anything.

This is just the first google result, there are countless others. And it is quite common knowledge.

Please instead of downvoting, see if this is fine from your point of view. No affiliation at all, I just don't like this kind of marketing.
Thanks for posting though.
