Enriched uranium - Wikipedia

Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235 U) has been increased through the process of isotope separation.Naturally occurring uranium is composed of three major isotopes: uranium-238 (238 U with 99.2739–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7202%), and uranium-234 (234 U, 0.0050–0.0059%).

Combination of flotation and magnetic separation methods is widely used for enrichment of feldspar ores by purifying from dark-colored gangue minerals such as iron and titanium. In this study, the removal of dark-colored minerals from feldspar ore (Aydin Cine region of Turkey) was studied using a dry magnetic separator. The effect of several parameters such as feed particle size, blade angle ...
