Phosphate concentrator at Eshidiya, of Jordan Phosphate Mines Co. Plc, Jordan treats two different types of ores. Both these ores are de slimed to remove clay minerals and the slimes are discarded as tailings. The discarded slimes contain P2O5 as high as 20%. Tests were conducted to use these slimes as direct P fertilizer in alkaline/saline soils both in Jordan and India. It is noted that the slimes along with N containing materials either of organic or inorganic origin work as efficiently as known phosphatic fertilizers.
