NettetUraninite is a highly radioactive and interesting mineral. It is the chief ore of uranium and radium, which is found in trace amounts. Helium was first discovered on the earth in samples of uraninite. Radium and helium are found in uraninite because they are the principle products of uranium's decay process. NettetUranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust.Uranium is one of the most common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial …
