  • Pyrite desulfurization by wet oxidation in alkaline

    The rate of oxydesulfurization of the two varieties of pyrite was studied under the leaching conditions of the Ames process. Concentrations of soluble sulfur species were determined for oxydesulfurization using leach solutions of sodium carbonate, sodium bicarbonate, distilled water, and dilute sulfuric acid and for alkaline leaching without oxygen using sodium carbonate.

    Originally published in Journal of Creation 9, no 1 71 92 Abstract. As with other radiometric dating methods, the U Pb and Pb Pb isochron methods have been questioned in the open literature, because often an excellent line of best fit between ratios obtained from a set of good cogenetic samples gives a resultant isochron and yields a derived age that has no geological meaning.
