Thorium ore is a naturally occurring mineral that contains the element thorium, which is a radioactive metal. It is primarily found in minerals such as monazite and thorite. Thorium is considered a potential alternative to uranium for use in nuclear reactors due to its abundance and the ability to produce less long-lived radioactive waste. The extraction and processing of thorium ore can lead to the production of thorium dioxide, which is used in various applications, including ceramics and as a potential fuel in thorium reactors. These reactors are seen as a safer and more sustainable option for nuclear energy compared to traditional uranium-based systems.
