A comprehensive investigation of REE in Florida phosphate was conducted by Kremer and Chokshi [62] of Mobil Research & Development Corporation in 1989. The total REE in Florida phosphate matrix analyzed 282 ppm (88 ppm neodymium, 68 ppm cerium, 57 ppm yttrium, and 49 ppm lanthanum, accounting for 90%).

2. Identify the primary wastes created during the different stages of phosphate fertilizer production and use. 3. Discuss how waste products are managed. 4. Describe the phosphate cycle, and how the use of chemical phosphate fertilizer alters this cycle. 5. Identify how air, water, and land can potentially be polluted by phosphate mining,

This work aimed to upgrade a low-grade sedimentary phosphate ore through attrition scrubbing/desliming and an anionic/cationic reverse flotation technique. The mineralogical and chemical examination showed that the sample contained low-grade apatite minerals (P 2 O 5 ~ 22.5%), and the main associated gangue minerals were …
