The phosphate formations cover approximately 60% of Jordan and comprise about 1 billion tones of resources. With its good rock quality, long term reserves, low production costs, and good geographical position to the Asian market, Jordan is now the second leading exporter of phosphate rock in the world and exports to more than 25 counties. Jordan with Al-Hassa Mine (3.5 million tones), Al-Abiad Mine (2.5 million tones) and Eshidiya Mine (3.25 million tones) produces 9.25 million tones of phosphate annually. The deposits at Eshidiya are comprised of overburden, four phosphate beds (A0, Al, A2 and A3), a coquina/marl waste bed, and two silicified phosphate/chert interwaste beds. At Eshidiya, the ore beds are treated separate through beneficiation and upgrading as it produces different grade products. They are classified into three classes, (1) Al Ore: requires crushing, scrubbing, screening and desliming to produce a 68-70% product, (2) A2 Ore: basically a direct shipping ore, which requires only two stages of dry screening to produce a 73-75% TCP product and (3) A3 Ore: must be washed, scrubbed and deslimed in a manner similar to Al and then floated to remove fine silica in order to make a 75-77% TCP product. A 65% TCP sub-commercial product is also produced.
