Uranium Known Facts and Hidden Dangers CCNR

When we extract uranium from the ground, we dig up the rock, we crush it and we leave behind this finely pulverized material it's like flour. In Canada we have 200 million tons of this radioactive waste, called uranium tailings. As Marie Curie observed, 85 percent of the radioactivity in the ore remains behind in that crushed rock.

The results imply syntrophic oxidation of hydrocarbons in oil sands tailings, with the activities of different carbon flow pathways to CH 4 being influenced by the primary hydrocarbon substrate. These results have implications for predicting greenhouse gas emissions from oil sands tailings repositories.

Tailings dam seepage at the rehabilitated Mary Kathleen

Dry capping of Mary Kathleen uranium mill tailings has resulted in physical containment of the wastes. The dry cover shows no signs of erosion and radiation levels are within acceptable limits. However, the dry cover was not installed according to original design specifications and hence, the flow rate of surface seepage from the tailings repository occurs at a much higher rate than predicted.

Enabling the recovery of metals and other valuable

The separate collection of slurries enriched with metals will optimize materials recovery, contributing to increase the lifetime and safety of tailing dams. This will have important positive impacts on social and environmental dimensions (by minimizing the need for new mines and larger tailings dams) alongside with enhanced mine profitability.
