Another research also demonstrated that the removal of dolomite carbonates from a marine sedimentary phosphate ore (80–250 μm) can be achieved through magnetic the separation process . The exploration of the magnetic separation process on the fine-grained rock phosphate ores was undertaken by Shaikh and Dixit [ 19 ], and the schematic flowsheet was given in Figure 3 .DOLOMITE EXTRACTION FROM PHOSPHATE PEBBLE BY,Specifically, several differences in the ore characteristics are noted. The fraction of coarse particles suitable for phosphate pebble is less. The P2Og content is lower. The amount of MgO is greater, owing to the presence of carbonate minerals, mainly (Ca, Mg)C03 (as dolomite) and CaC03. Phosphate rock with P2Og content from 26World Phosphate Deposits | Geology for Investors,17-10-2019· Introduction. Phosphate Rock (PR) has long been an important agriculture-based commodity. Most soils are phosphate deficient, and with the majority of 3rd world countries relying on cereals which require phosphate rich environments to thrive, the need for further phosphate exploration and exploitation will continue to grow well past 2050.
