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 99.2732–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7210%), and uranium-234 (234 U, 0.0049–0.0059%).

The conversion of grains to flour involves several steps that vary with the type of grain used. The initial stages of processing remove the bran and the germ of the seed. . The bran is the outermost layer of grains that contains fiber (primarily insoluble), some protein, and trace miner
Natural uranium is made weapons-grade through isotopic enrichment. Initially only about 0.7% of it is fissile U-235, with the rest being almost entirely uranium-238 (U-238). They are separated by their differing masses. Highly enriched uranium is considered weapons-grade when it has been enriched to about 90% U-235. [citation needed]
Chaptalization is sometimes referred to as enrichment, for example in the European Union wine regulations specifying the legality of the practice within EU. [ 2 ] The legality of chaptalization varies by country, region, and even wine type.
Enrichment culture is the use of certain growth media to favor the growth of a particular microorganism over others, enriching a sample for the microorganism of interest. . This is generally done by introducing nutrients or environmental conditions that only allow the growth of an organism of inte

Supergene enrichment occurs at the base of the oxidized portion of an ore deposit. Metals that have been leached from the oxidized ore are carried downward by percolating groundwater, and react with hypogene sulfides at the supergene-hypogene boundary.
