    It is unprocessed in the sense of the poster I was replying to, meaning it is not composed of man made chemicals. It's just rock.
    Sorry to have been careless - but hell, you really didn't know what I was talking about?
    No, it's not. It's one step - one very, very, well paid and profitable step - from that. Inches, not miles, would be the metaphorical unit; single digits the metaphorical number.
    "Obviously" ? Beg to differ.
    Living and learning about hard rock mining corporations (and related industry).

    Minus your exaggerated cartoon of unconcealed mine spoil, crediting the bad guys with some minimum of brains here, that is exactly what will happen in the absence of the regulatory oversight I partly detailed above.

    The expense and the scale of the efforts necessary to impose regulatory oversight on a hard rock mining company is a factor in this proposal, is all. It's part of the calculation.

    Mining companies don't make rock dust. So they have no product to offer to a farmer, legal or otherwise.

    Some do, or will, if presented with the opportunity here.
    Others will outsource - contract with whomever does, preferentially with another subsidiary of the holding company that owns them, or a company with lots of political pull, or a temporary shell company set up to go out of business easily and quickly at need.
    One doubts the farmer will be paying for this "product" at all - they aren't paying for it now, why would they ever?

    But this is digression: Did you have a point?

    To recap: You are (or appear to be) objecting to my observation that the proposal here features obvious opportunities for an amoral and unethical mining company (or - in the spirit of reality acknowledgment - its executive management and major investors) to make good bank by lying and cheating and behaving as mining companies have been behaving since before the term "capital" was invented,

    and that experience tells us the costs of preventing them from doing so will be much larger than the prevailing wisdom seems to assume, while the process of preventing them from doing so will involve a degree of diligence and competence in government oversight and enforcement not often encountered in these circumstances.

    That's all. I like the idea - it's just that it's not necessarily going to be cheap, and funds are going to be limited.

    Yes I had a point, which is a reasonably clear one, so I won't re-explain it.

    climate change control?
    huh wut?
    CO2 ain't climate
    ........................
    damned sloppy use of the language?

    Nope. Most people understand the link between higher CO2 levels and climate change.

    I never claimed that there wasn't a link.
    (it's a set and subset problem)

    You remind me at times of the local fox, which likes to crap outside my front door from time to time, just so I don't forget he's there. What I generally do is wait for a bit for the turd to dry up, then scrape it up and flick it into the road with a trowel.

    You too,
    and
    don't forget to add more crushed carbonate rock dust to your fields
    You too
    can "change the climate"

    No, you're reading the reaction in post 1 backwards.

    Bicarbonate and silica are what you end up with, not what you put on the fields. The rock dust should be metal silicates, which take up CO2 as they change to (bi)carbonates and silica.

    That's point, you see, to absorb CO2 from the air and convert it into carbonate type minerals.

    Ah, good. So you meant "damned good use of the language."

    for a snake-oil salesman--------maybe
    ..............................
    If you want to claim that it could absorb CO2
    why not just say that?

    ...................
    basalt, anyone?

    Great idea! Perhaps in the original post the OP could say that! That it "proposes a man-made adaptation of the geological Carbon-Silicate Cycle* as a way of sequestering significant amounts of CO2 from the atmosphere." Check out the original post and see where you could insert that claim!

    Foxes generally have a better sense of "perspective" than sculptor.

    Because what the paper says is, not only that it can take out CO2 from the air, but also that this ".....is now necessary for the mitigation of climate change."

    This is what I have faithfully reflected in the title and in my contributions to the content of the thread.

    This is where the science now is, today, whether you like it or not.

    This almost reads as self-parody. (Almost?)

    Errors concerning kind and degree are kinda your forte, you know.

    ~30 years back, I saw Douglas Hofstadter deliver a lecture at CalTech on the many varieties of the duck-rabbit illusion. He was focusing specifically on lexical varieties, though I forget his particular name for them. Anyways, during the lecture, I actually created one. Read one way, it said "butthole." Turn 90 degrees clockwise, it read "surfers." (This was 1990, so...) I was pleased with myself--probably a lot more than I should have been. Generally, these things don't cause much confusion for people--or rather, the kind of confusion they do cause is illustrative of their intent. Hence the lifelong obsessions for many an artist, musician (Ligeti, especially--papa (Gyorgy), though probably Lukas, as well), writer, poet, philosopher. If, however, one's "confusion" is of the "denial of ambiguity" kind, one is either trolling, or possibly needs to take that Montreal Cognitive Assessment thingy.

    pssst
    (that was a joke)
    and
    irony
    each year, thousands of tons of crushed carbonate rock are spread on farm fields in Iowa, and more throughout the midwest corn belt.
    Now if the same result can be had from a mineral that absorbs CO2 rather than releasing it
    that would be interesting-------------and, then comes efficiency and cost effectiveness

    .................................
    oh, and
