Leaching behaviour and the solution consumption of uranium

commodity prices made heap leaching unattractive since there were still large amounts of high grade uranium ore globally available at that time. As the high grade uranium ores have been consumed, many countries have turned to heap leaching (Taylor, 2013; Scheffel, 2010; Taylor, 2007; Carlsson and Büchel, 2005; Scheffel, 2002; Shakir et al., 1992).
