Rare Earth Elements Found In Jamaican Mud

stevegee58 writes "Jamaica was once home to a thriving bauxite (aluminum ore) industry. While Jamaican bauxite mining may have fallen on hard times, it seems that the bauxite tailings in the form of red mud are rich in rare earth elements. Japanese researchers have discovered rare earth elements in high concentrations in this red mud and have already invested $3M in a pilot project to extract them. Perhaps Chinese dominance of rare earth deposits is on the wane as global manufacturers continue to search for and find other deposits of these valuable minerals."

    Rare earths are NOT rare. They are in fact abundant in the crust.

    The problem with these materials is that deposits of rare earths are usually associated with stuff like Thorium. This makes the mining waste rather annoying.

    China has been willing to ignore this problem thereby cornering the market. Now they are getting the idea that being the world depository of rare earth mining waste may not be a good idea and are declining to sell to every Tom Disk and Harry at cut rate prices.

      There is a major difference between talk and prototyping. We built small scale prototypes of liquid thorium salt reactors forty or fifty years ago, but politics shut down the development when money was requested to go the next step and build a prototype to scale. We could pick up where we left off in less than a year if money were committed not to paper research that delays the project indefinitely but to prototyping and practical engineering, actually building one or more of the damn things and tinkering as we go to solve engineering problems in situ, not in theoretical analysis.

      We could revive the last working thorium design in at most a year or two -- it didn't take that long to build the first time. We could be working on scaling it up in parallel, so that we had a working scale model in four or five years tops. We could be building working full scale LFTR power plants by 2020, and could solve both the "carbon problem" and the world's energy poverty problem by 2030 to 2040 and coast to world peace and abundance by 2050. The cost through the working scale model is on the order of a few billion dollars, tops. We used to spend that much in Iraq every week.

      Or we could continue to dick around investing billions into wind power that requires the rare earth magnets that come from processing Thorium rich salts somewhere and that don't generate power when the wind doesn't blow, which is most of the time. We could continue to drop billions down the rat-hole of defending "free" access to major oil deposits under the guise of defending national security or promoting personal and religious freedoms for people living half a world away. We can make bankers and corporate interests rich with complex 'carbon trading' schemes that so far have had zero effect on global CO_2 levels at enormous annualized costs, costs so great that they probably single handedly caused the European banking crisis (or could have ameliorated it in any event). We spend more money on long-shot always a decade away fusion energy than we do on LFTR, and burned more federal money on solar cells in one failed company than it would cost to get started on LFTR.

      There is a singular lack of urgency in thorium based energy research and investment. Too many people make too much money within the status quo.

    Finding "rare" earths isn't that difficult. In this country, the problem is that rare earth elements (technically lanthanides) are invariably associated with the other f-series elements (the actinides), specifically thorium. Mining rare earths produces thorium oxide as a byproduct, and "disposing" of this ought-to-be-valuable stuff is a real difficulty. In China, it's less of a problem, for two reasons. First, it's apparently OK to dump radioactive waste in your local waterway, and second, the Chinese government doesn't shun all things nuclear. Like reactors, and bombs, and Oh Yes, thorium deposits.

    Now, finding rare earth deposits with almost no thorium in them is a real feat, and getting the US government to find ways to store thorium would a world-class miracle.

    Are you saying that the issue is that there's no way of storing thorium acceptable to the regulators, or that you want to have the government responsible for handling the cost of storage? Because those are very different things: The first case is legitimately the regulator's fault, but the second case is businesses just trying to make the taxpayers pay their costs of doing business.

    Uhm why not just put the Thorium back into the mine, where it came from?

    That is often impossible in an active mine, and in a strip mining situation there is no "mine" to put it into.

    By its nature mining takes solid consolidated rock in which nasty materials are locked up (which is why they are there to be found in concentrated form) and turns it into powder from which is now easily leached or transported by water and wind. It is possible to find ways to secure the tails, but that costs money and drives up prices (making the product less competitive) or cuts into profits, both of which mining companies hate. Only strict outside (usually government) oversight keeps mining companies from turning most every mine site into a leaky, ugly toxic waste dump.

    North Carolina has Uranium as well, but there is so strong a NIMBY movement that any politician that suggested that we mine it and achieve energy independence in the state would find himself going to hell in a handbasket. Thorium too -- in the form of Monzanite Sands, which are -- surprise -- around 24% lanthanum, about 17% neodymium, and full of other useful stuff as well. The minute somebody realizes that national "rare earth shortages" are complete bullshit caused almost entirely by our reluctance to treat Thorium as a potentially useful nuclear fuel instead of as a pollutant, there will be hell to pay, but in the long run North Carolina has more than enough heaven in it to compensate.

    Personally, sitting as I am a mere fifteen or twenty miles from Shearon-Harris (a pressurized water nuclear plant with one of the largest nuclear waste cooling pool facilities in the world) I'd be thrilled if our state took a hell of a risk and directly invested in the promotion of rare earth mining with the deliberate extraction of the associated Thorium and in the further investment in Thorium based nuclear reactors that produce "no" nuclear waste in comparison with Uranium Oxide, but between NIMBY and corporate interests that currently make shit-piles of money providing UO fuel or coal based energy, it will be a cold day in Half Hell, NC before that happens.
