leaching was introduced to the uranium industry in the 1950s by the Portuguese to extract uranium from low grade uranium ores (Scheffel, 2002). The environmental concerns, low grades and low commodity prices made heap leaching unattractive since there were still large amounts of high grade uranium ore globally available at that time.
