The search for uranium in Niger began in the 60s and its mining in the 70s. As given the drop in uranium prices in the 80s, these activities decreased significantly. The exploration activities took place in 2006 when many mining companies were very interested in the research of this radioactive metal (uranium). In 2007, Niger had more than 150 exploration licenses (all minerals included) whose...

The quest for uranium in the Philippines dates back in the mid–1950s and to date about 70% of the Country has been systematically explored, from reconnaissance to some detailed level using the combined radiometric and geochemical survey methods. However, no major uranium deposit has been discovered so far, only some minor mineralization. Also, there is a general view that the geological...

In the processing of uranium ores, uranium is recovered from mill leach solutions and is transported to a processing plant. This step allows obtaining an uranium concentrate by precipitation. After drying, a solid uranium concentrate is produced (called “yellow cake” due to its color and its doughy texture at the end of the procedure), containing around 75% uranium. The “yellow cake” is sent...
