    Assessment Of Radiological Hazards In The Phosphate Mining

    jun 01, 2021 also, there are numerous publications related to the radioactivity of phosphate ores, fertilizers, wastes and their associated radiological impacts throughout the world (e.g. refs. 4,12,13). the phosphate mining and processing is the main industry in togo considering the economic aspect.,p is for phosphate could urine solve a fertilizer shortage,jun 16, 2016 with reserves dwindling, miners are forced to extract phosphate from lower-quality ores, which means more mining, more purification and more energy inputs, all of which translate to greater costs. like peak oil, peak phosphorus is the point at which phosphate production will reach maximum output before beginning to decline.
