Ukashat


A phosphate mine producing about 1 million tons/year. Started 1982.
Located 420 km West of Baghdad on the border with Syria.
Mining takes place in two pits. Phosphate rock is crushed and loaded onto rail cars for shipment to the fertilizer plant at Al-Qaim. Akashat is also the main uranium mine of Iraq, associated with the Al-Qaim plant.

The Paleocene Akashat Formation contains the main phosphorite deposit in western Iraq. The phosphorite beds occur mainly in the middle part of the formation and have a maximum thickness of 11 m. They thin southward to about 7 m south of the Rutba-Amman Highway and there is a lateral change to marl and marly limestone. The uppermost 4 m of the formation are composed of shelly limestone with chert nodules. Thin beds of limestone and chert are also present. The phosphorites are pelletal (granular) in texture and consist of phosphate pellets and oolites (Al-Bassam, 1990) with carbonate and silica cements.

The radioactivity of the Ahashat phosphorites, which generally contain 32–45 ppm U and up to 100 ppm U in the apatite concentrates, is mainly due to uranium incorporated in the carbonate-rich fluorapatite structure (as U4+) and to a lesser extent to secondary uranium minerals (carnotite and metatyuyamunite) and decay products of uranium.
