lithium recovery: https://trace.tennessee.edu/cgi/viewcontent.cgi?article=3421&context=utk_chanhonoproj https://trace.tennessee.edu/cgi/viewcontent.cgi?article=3421... Seems possible; not sure of economic value at this particular point in history. There's a bunch of recent headlines about trivial extraction of lithium from seawater, so might get less economically feasible if those techs pan out. OTOH, even if it's not obviously worth it, you could try burying it all in one place and then 'mine' it once the economics swing towards recovery.
