This study used data from an investigation into the mapping of manganese-iron (Mn-Fe) mineralization, located within the Um Bogma formation. The ore takes the form of patchy isolated bodies or lenses in the three members of the Um Bogma formation located in East Sinai, Egypt. Magnetic, resistivity, and induced polarization (IP) surveys …
Introduction. Economic iron ores (270 million metric tons of iron ore deposits) with an average of 47.6% Fe occur in the Bahariya Oasis (Said, 1990).The iron ores are exploited now as raw materials for the Egyptian Iron and Steel Company, Helwan, Egypt. Due to their geological and economic significance, such deposits have been …

It is one of the largest arc sedimentary rock sequence affected by faulting and folding due to repeated stages of deformation. The iron deposits in this area are of oolitic type and …
This chapter reviews four types of non-metallic ore deposits in Egypt. These deposits are phosphate, white sand (glass sand or silica sand), argillic and evaporite deposits. ... At least 4000 years ago, long before iron was smelted; glass-making was already a known craft. The oldest known specimens of glass were obtained from …
The Egyptian iron and steel industry has depended mainly on the iron ore reserves of Aswan from 1956 to 1972. After this date, Bahariya area (Western Desert) …

Mineral deposit - Iron Ore, Ore Bodies, Mining: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world's great mineral treasures. There are two major types of deposit. The first, and by far the most …

Some deposits are also strongly altered, often developing a porous texture (Fig. 3f). Many of the iron ore deposits (e.g. Gebel Semna, Gebel Hadrabia and Abu Merwat) are characterized by high Fe and low Si contents in comparison with Algoma, Superior, or Rapitan BIF types (Fig. 7, Table 2), whereas others (e.g. Gebel El Hadid and Wadi El
