History. Some minerals, such as high-grade iron ore, phosphate, mercury, and zinc, have been exported since the early 1970s.The state mining and prospecting corporation, the National Company for Mineral Research and Exploration (Société Nationale de Recherches et d'Exploitations Minières), was established in 1967.

The influence of microwave treatment on the liberation of iron ore from the high phosphorus oolitic iron ore from Aswan region, Egypt was studied. The effect of microwave power, exposure time and grain size on the liberation of iron ore was investigated.

Minette type oolitic iron ore occurs within the Upper Djebilet Formation of Pragian (Lower Devonian) age. At Gara Djebile, three large lenses form three individual deposits, extending east-west for about 60 km, namely Gara West (14 x 4 km and 0 to 30 m thick), Gara Centre (20 x 5 km and 0 to 30 m thick) and Gara East (7 x 1 km and 0 to 9 m thick).

150-2 most important economically being the El -Sebaiya (west Mahamid) and El Mahamid deposits near El Sebaiya. Because of the increasing world demand for phosphate, P 2 O 5 content of the ore is gradually falling, and it is becoming economical to mine and beneficiate many lower-grade deposits (El-Jalead et al., 1980).

This paper deals with the mineralogy and geochemistry of the economically most interesting Egyptian iron-ore deposits. It is specifically concerned with the examination of the iron-ores occurring at East Aswan, in the Eastern Desert, at Bahariya Oasis, in the Western Desert, and in several ...

Three types of iron-ore have been distinguished in the provided areas; (1) Ferruginous sandstone iron-ore, (2) Oolitic iron-ore and (3) Ferruginous concretion iron-ore. Fe 2 O 3 content in the Ferruginous sandstones reaches up to 70.46%.

About 76% of these are iron ore, 11% are pigment, and 2% are other iron. A wide variety of iron ore options are available to you, such as hematite, magnetite, and pyrites. You can also choose from lump, mine, and fines (powder).
