rikastetusta

Rikastetusta is a Finnish term that translates to "enriched" or "concentrated" in English. It is most commonly used in the context of nuclear technology and geology. In nuclear physics, "rikastettu uraani" refers to uranium that has had the concentration of the fissile isotope uranium-235 increased. Natural uranium contains only about 0.7% uranium-235, while enriched uranium can have concentrations of 3% to 5% for use in nuclear power reactors, or much higher percentages for nuclear weapons. The process of enrichment involves separating uranium isotopes based on their slight mass difference, typically using gas centrifuges or gaseous diffusion.

In geology, "rikastetusta malmista" refers to enriched ore. This indicates that a particular mineral or metal has been concentrated in a specific geological deposit to a level that makes its extraction economically viable. For example, a rock formation might be considered enriched in gold if the concentration of gold exceeds a certain threshold, indicating the presence of a gold deposit. The term signifies a higher-than-average concentration of a valuable substance, making it a target for mining and resource extraction.
