What happens if we treat phosphate rock with Sulphuric acid?
Treatment with sulfuric acid leads to the production of gypsum (phosphogypsum), which retains about 80% of Ra-226 and 30% of Th-232 and 14% of U-238. This means that uranium and thorium are enhanced to about 150% of the value of the beneficiated ore, making it a significant NORM.
