Algeria has important phosphate reserves (2 billion tons) located in the east of the country at Djebel Onk. This mining district is located in the northwestern part of the Algerian Sahara near the Algerian-Tunisian border. The granulo-chemical and XRD analytical results confirm the phosphate depletion of Bled El Hadba layer and their enrichment in carbonate and dolomite, in comparison with the layer of Kef Essennoun. Phosphorite particles are heterogeneously grained. Although the two deposits are relatively close to each other, they show different mineralogical and chemical characteristics, which may cause the use of different mining exploitation methods.

Algieria posiada ważne rezerwy fosforanów (2 miliardy ton) zlokalizowane na wschodzie kraju w Djebel Onk. Ten obszar górniczy znajduje się w północno-zachodniej części algierskiej Sahary, w pobliżu granicy algiersko-tunezyjskiej. Wyniki analiz granulochemicznych i XRD potwierdzają zubożenie fosforanów w warstwie Bled El Hadba i ich wzbogacenie w węglan i dolomit, w porównaniu z warstwą Kef Essennoun. Cząstki fosforytu są niejednorodnie ziarniste. Chociaż oba złoża znajdują się stosunkowo blisko siebie, wykazują różne właściwości mineralogiczne i chemiczne, co może powodować stosowanie różnych metod eksploatacji górniczej.
