Document Summary

We produce about 20% of the world"s uranium (75% of global reserves) followed by australia and ussr. Nuclear energy accounts for about 15% of canada"s electricity supply (increasingly more being sent to. China hopes to open 42 nuclear plants by 2019. Nuclear plants do not contribute to greenhouse gas emissions. Locate deposit (difficult to find if under ocean floor, etc. ) *** looking in areas in the arctic very disruptive for ecosystems*** Cover old trench with new overburden (looks nice from a distance) Tantalum is used in high end batteries because it can hold a good charge. Unfortunately it is found in countries that have very few regulations the congo. This is happening in the tar sands in alberta. Uses lots of water ends up containing things like mercury from filtering coal then they have to keep putting it into larger and deeper pools because its contaminated. About 80% of mined ore made of impurities.
