Uranium leaching

Abstract

Language:

This chapter describes the acid leaching of Elliot Lake uranium ores using sulphuric acid and pachuca tanks as the primary contactors. It explains the fundamental leaching chemistry, emphasizing diffusion-controlled dissolution of uranium oxides, the role of air for agitation and oxidation, and the possible uranyl sulphate complexes formed. The text identifies key operating variables—acid concentration, temperature, agitation, liquid–solid ratio, reaction time, and particle size—and outlines how each affects uranium extraction efficiency and downstream solid–liquid separation. It details the design and operation of major process units, including disc filters, pachucas, and a heat-recovery system for off-gases, and provides typical circuit layouts and retention times. Operating practices for controlling acid addition, temperature, air flow, pulp density, and grind size are discussed, along with the impact of acid-consuming gangue minerals on reagent requirements. The chapter concludes with practical guidance on equipment maintenance, focusing on filter cloth condition, air and steam lance integrity, and rubber lining inspection.
