Leaching behaviour and the solution consumption of uranium

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. As the high grade uranium ores have been consumed, many countries have turned to heap leaching (Taylor, 2013, 2007; Scheffel, 2010, 2002; Carlsson and Bchel, 2005; Shakir et al., 1992)....

SOMAIR Wikipedia

Lower grade uranium are exploited up to deeper depths of 90 metres (300 ft)), but with lower ore extraction rate of 0.20 0.25%. During 2005-06, new leach pads were constructed over the old ones. The new leach pad is capable of handling 17 million tonnes of uranium ore which could yield 1.4 million tonnes of uranium extract per year....

Uranium processing: from ore to "yellow cake" AREVA

SOMAR has been using this modern method for the extraction of uranium from low-grade ores ( < 0.10%) since 2009. This process is called "heap" leaching because the ore is stacked up. It is the first time that leaching has been used in uranium mining....
