High Grade Phosphate from Syrian Phosphate at Eastern Mines

Syria is one of the major sedimentary rock phosphate producing countries in the Middle East from the Khneifiss, Eastern "A" and Eastern "B" mines. The phosphate rock of Syrian mines is being upgraded by increasing P205 content to higher values (>28%) suitable for fertilizers and other industries. But it is not always possible to do so due to interlocking of other contents such as the higher CaO/P,05 ratio, and the high chlorine and R,03 (Fe203+A1203) contents
