INTRODUCTION
The Athabasca Basin of northern Saskatchewan (and a small part of Alberta), Canada is a major source of global uranium (U) supplies. Uranium mined from the Basin comprised 22% of the world’s supply in 2015, and, as of 2014, there are 235,000 tons of known economically mineable U in reserve in the Basin [1, 2].
There are three U mills currently operating in the Basin (Rabbit...

INTRODUCTION
Between 1946 and 1990 in total 216,300 t U were produced by mining and milling facilities in the Eastern part of Germany[1]. A Soviet and later Soviet-German-joint-Stock company was responsible for the uranium production in the German Democratic Republic prior to the German unification when uranium production was stopped due to economic and political reasons. As successor of...

INTRODUCTION
This paper presents the results of recent studies carried out at the former Uranium production facility Pridneprovsky Chemical Plant (PChP) in Ukraine and describes specific activity concentrations of radionuclides of U-Th decay series with specific focus on identified high activity concentrations of 230Th associated with different environment compartments, such as soils,...

INTRODUCTION
High-grade, copper sulfide concentrates, (typically greater than about 25% w/w Cu), are commonly treated via pyrometallurgical routes, while hydrometallurgical routes are typically favoured for lower grade or impurity bearing concentrates. The processing routes for the treatment of copper concentrates can also be influenced by the presence of minor valuable metals such as...

INTRODUCTION
Contamination of groundwater and surface water by arsenic, molybdenum and selenium derived from both natural and anthropogenic sources is an issue of global concern. Uranium-bearing ore material often contains all three of these elements of concern. Sulphuric acid leaching of these ores results in liberation of arsenic, molybdenum and selenium. In the hydrometallurgical...
