Electrochemical Trace Analysis of Valuable Minerals in Uranophane

Abstract

Extraction of Uranium from the ores involves various methods like - leaching, hydrometallurgical or pyrometallurgical processes, RAMAN Spectroscopy, Differential pulse Polarography, etc. Physical methods of pre-concentration have unfortunately not been successful in case of uranium ore minerals. The reasons include the impracticality, uneconomical, etc. the accepted uranium resource processing steps consist of: (1) bringing uranium present in solid matrix into solution through leaching, (2) concentration and purification of dissolved uranium, (3) precipitation of the concentrated and purified dissolve uranium into a suitable chemical intermediate. In this work we propose a technique which will eliminate uranium interferences in uranophane mineral by applying an electrolytic extraction. The purpose of this paper is to provide a review of Uranophane deposits, production and consumption, mining ore processing and above all to explore the Differential Pulse Polarography (DPP) method of instrumental for determination of trace elements in ore.
