The Agency for Toxic Substances and Disease Registry (ATSDR), based in Atlanta, Georgia, is a federal public health agency of the U.S. Department of Health and Human Services. ATSDR serves the public by using the best science, taking responsive public health actions, and providing trusted health information to prevent harmful exposures and diseases related to toxic substances.
The critical metals were recovered either by direct conversion to the respective carbonyls or as upgraded products by carbonyl removal of an undesirable metal. Best metal-to-metal carbonyl conversion was under CO pressure, from 80 atm upward, and at 1400 C. Carbonylation was accelerated by the addition of HzS in small quantities.

· Chordoma is a rare type of bone cancer that happens most often in the bones of the spine or the skull. It most often forms where the skull sits atop the spine (skull base) or at the bottom of the spine (sacrum). Chordoma begins in cells that once made up a collection of cells in the developing embryo that go on to become the disks of the spine.
This paper reports that as part of the U.S. Bureau of Mines program to reduce the Nation''s reliance on foreign supplies for critical metals, a procedure was devised to separate and recover critical metals from mixed and contaminated superalloy scrap. The process uses both pyrometallurigical and hydrometallurgical, methods to treat the scrap. The mixed scrap is converted to a matte containing 4 ...

· 1. Introduction1.1. Rare earths ores. The term rare earths was originally used to designate the lanthanoids in row 3 of the periodic table which includes oxides of scandium (Sc, 21), yttrium (Y, 39), lanthanum (La, 57) and the 14 elements following lanthanum in the periodic table of elements, i.e. from cerium (Ce, 58) to lutetium (Lu, 71) inclusive.
To decrease reliance on foreign sources for the strategic and critical metals gallium and germanium, the U.S. Bureau of Mines identified and developed processing technology for two domestic sources of these metals: a Tennessee zinc residue and a Utah ore. Sulfuric acid (H2SO4) solutions were used to solubilize gallium and germanium in both sources.
