This invention relates to a method and apparatus for gasifying or liquifying coal. In particular, the method comprises reacting a coal with a molten aluminum or aluminum alloy bath. The apparatus includes a reaction vessel for carrying out the reaction, as well as other equipment necessary for capturing and removing the reaction products. Further, the process can be used to cogenerate electricity using the excess heat generated by the process.

Disclosed is a process for the selective removal of copper compounds, and other impurities with respect to molybdenum and rhenium, from concentrates of molybdenite (MoS.sub.2) with a copper content that is higher than 0.5% in dry weight.

A method of preparing remediated MoO.sub.3 from naturally-occurring molybdenum, or molybdenum that is enriched in one, the other or both of Mo-98 and Mo-100 isotopes from a particulate rhenium-containing MoO.sub.3 matrix that contains one, the other or both of those isotopes is disclosed as is the product remediated MoO.sub.3 that contains less than about 1000 ppt rhenium. In accordance with the invention, particulate rhenium-containing MoO.sub.3 matrix is heated in the presence of an oxygen-containing gaseous stream to a temperature of greater than about 300° C. and less than about 800° C. The temperature and oxidative sparging are maintained for a time sufficient to assure that rhenium has been oxidized to rhenium(VII), diffuses to form the dimer (Re.sub.2O.sub.7), and is then vaporizingly removed as Re.sub.2O.sub.7, while retaining the remediated MoO.sub.3.

Provided herein are methods of sequestering target elements (e.g., rare earth elements and/or radiometals) from a sample, methods of purifying target elements from samples, pharmaceutical compositions comprising target elements, and methods of treating a subject with said pharmaceutical compositions.

A method for extracting secondary metal values from a sulfuric acid leachate is provided. The method includes providing a leachate which contains a primary metal and a plurality of secondary metals, wherein the primary metal is selected from the group consisting of Cu, Li and Ni and is derived from sulfuric acid leaching of an ore; passing the leachate through a first ion exchange resin which is selective to, and releasably binds, the plurality of secondary metals; stripping the plurality of secondary metals from the second or third ion exchange resins, thereby obtaining a first extract; and recovering the secondary metals from the first extract. In some embodiments, prior to passing the leachate through the first ion exchange resin, the leachate is passed through a second ion exchange resin which is selective to, and releasably binds, one of the plurality of secondary metals. The one of the secondary metals is then stripped from the second exchange resin, thereby obtaining a second extract, and the one of the secondary metals is recovered from the second extract.
