Pyrometallurgical Processing of Nuclear Fuels by Molten Zinc

The Obtained of Concentrates Containing Precious Metals for Pyrometallurgical Processing

G. Siwiec, B. Oleksiak, J. Wieczorek Silesian University of Technology, Katowice, Poland A. Blacha-Grzechnik Silesian University of Technology, Gliwice, Poland In the presented study the flotation process has been proposed as a method of enrichment of silver-bearing jewellery waste. This method, traditionally used for the enrichment of non-ferrous metal ores, is based on differences in wettabil...

Zinc Ion Self-diffusion in Molten Zinc Bromide

The oven, in which the diffusion runs were carried out, was built of a vertical glass tube with a Kanthal winding (see Fig. 1). This winding was supplied with some extra terminals; shunting parts of it allowed the temperature to be kept constant (or slightly increasing upwards) over a sufficient length in the oven. The insulation consisted of rockwool, a section of which could be removed tempor...

Storage of spent nuclear fuels in nevada.

American Asociation forthe Advancement of Science Science serves its readers as a forum for the presentation and discussion of important issues related to the advancement of science, including the presentation of minority or conflicting points of view, rather than by publishing only material on which a consensus has been reached. Accordingly, all articles published in Science-including editoria...

Improved Rigid Ion Model of Molten Zinc Chloride

We have developed a new rigid ion model for the simulation of molten ZnCL. A molecular dynamics simulation of this model under a constant pressure of 1 atm and a constant tempera ture of 1200 K resulted in a successful description of the short-range order in the liquid state. The resulting short range structure is presented with respect to the coordination of the Zn 2+ ions and the Z n C I Z n ...
