REDOX SYSTEM Fe~(2+):Fe~(3+) AT AN UNDERGROUND LEACHING OF URANIUM

摘要

One of perspective energy sources is the uranium 235 isotope core fission test. Economic, ecologically safe and high-tech method of extraction of natural uranium is the sulphuric-acid underground leaching (UL). Basic process in extraction of uranium in the method of UL is oxidation and dissolution of uranium in a subsoil, and its extraction on a surface in solution. The main advantages of a method of an underground leaching are possibility of working on the high-water of the fields, poor off-balance ores for a mountain way, reduction of term of commissioning automation of processes production and processing of productive solutions on a surface. Earlier it was specified in scientific literature that an optimum oxidiser is iron(III), but did not consider as Fe~(2+):Fe~(3+)system, and their concentration.
