The phosphate Extracting

The phosphate Extracting

Phosphatic sediment dating site right to Akashat configuration (era Vertical section consists of these deposits of rock facies following (from bottom to top) (Figure 3): -

· Clay brown to black in color (1 meter).

· Stone clay Jerry Mtdelmt Supreme perforated surface (2 meters).

· Phosphate Dmgay Sri contain an abundance of coarse grained bones of a dark gray color of 0.3-0.7 meters.

· Limestone clamshell containing phosphate fossils (0.5-2 meters).

· Phosphate Dmgay, good screening, fine grained, gray in color, medium hardness contains solid Adissat in the middle and crisp or incoherently at the top, representing the major industrial class (9-15 m, average 11 m).

· Limestone clamshell cave gelling hostile Supreme phosphate (4.10 meters).

· Coarse grained phosphate Dolomiti (1 meter).

· Stone clay Jerry Mtdelmt contains a flint (10-20 meters).

· Clay Vosvaata, gray (1 meter).

· Limestone contains the bones of phosphate phosphate (2-3 meters).

       Above this relay calcareous rocks anti-gelling with very good specifications as the raw material for the manufacture of cement and other industries (0-45 m average 19 m) and return these rocks to composition Alrtkh (Eocene age). Depth of the groundwater in the area more than 200 meters and impressive compositional activity appears cracks main trend East - West cut phosphate sludge and divide it into several segments generally fall towards the north-east. The general trend for miles classes is toward the north by 4-5 m / km.

Mineral composition and chemical phosphate

     Metal phosphate only is Frenkolayt (Alabtaat Filordi Alcarboneta) located granules (Dmalq, Sriat, bones, ...... etc.) The material consists of coarse calcite Association to average shape. The overall rate for presence Frenkolayt in industrial phosphate layer is about 60% and the remaining phosphate is the most important components calcite
