The heavy mineral concentration in different raw sand samples resulted by heavy liquid separation technique revealed that the average abundance of heavy minerals is 69.67% in Kutubdia island and 9 ...
Copper. Copper was the first metal used by ancient Egyptians. They mined the metal up to 5,000 years ago and, in fact, the oldest Egyptian artefacts made of copper date to the early fourth century and consist of beads and small tools. Copper was rarely found in a pure state, often containing small amounts of zinc, iron, or arsenic. Eventually ...
Starting from the south, those delta-front deposits, which floor most of the narrow-shallow basin of Lake Nubia, are characterized by thick coarse-grained sandy deposits, rich in heavy minerals (averaged 12.8%). This delta-front is followed to the northeast by thin layers of prodelta mud, poor in heavy mineral contents (averaged 0.6%).
Ancient Egypt had the means and knowledge to explore for needed mineral ores, establish mining processes, and transport heavy loads for long distances by land and sea. Because it being was largest and richest population in the ancient world, Egypt imported huge quantities of raw materials; and in return exported large quantities of finished goods.

which are common heavy minerals in Egyptian black sands have been determined. The minerals can be used for genetic and provenance studies. They indicate that the black sands were derived from the Nile sediments which were derived from the igneous and metamorphic complex along the upper reaches of …
The floods associated with the pluvial periods which prevailed in Egypt during the Pleistocene, were able to erode the source rocks and liberate heavy minerals including monazite. The mineral grains were transported through several wadis and tributaries to the main channel of the River Nile.

the heavy minerals comprising these deposits varies from place to place. The greatest concentrations are located close to the outlets of the River Nile. The beach area of Rosetta contains most of the economic heavy minerals reserves of black sand in Egypt owing to their great extension and high grade (Dabbour, 1995). The beach sand placer ...
Three hundreds and six black sand samples have been collected from the beach areas along the northern coast of Egypt, parallel and perpendicular to the shoreline.The mineralogy and chemistry of the economic heavy minerals were studied. The grain size distribution of the studied economic minerals shows a unimodal class that mostly in the very fine sand size.
Introduction Heavy-mineral sands deposits, including the rare-earth-bearing mineral monazite, occur at several sites along the Mediterranean coast of Egypt, where the Nile River has formed a vast delta. Covering 22 000 km2, the Delta's economic heavy-mineral sands predominantly occur where existing and ancient extinct branches and estuaries of ...
More recently in Egypt, interests have been focused on the economic values of heavy minerals or black sand placers in the coastal and nearshore Nile delta sediments (Abu Halawa, 2005; Frihy et al., 2015) and their sorting and deposition patterns (Frihy, 2007).
Egypt's black sand deposits are located in the Nile Delta between Alexandria and Rosetta. They contain substantial reserves of heavy-mineral sands. This paper discusses the geologic history of the Nile Valley and the possible source of heavy minerals.
distribution of a heavy mineral in the Nile Delta coastal sands appear to depend on: (1) range of grain size fractions in each sample, (2) relative availability of heavy mineral in each size grade of the sample, (3) specific gravity of minerals comprising these sands, and (4) some other unknown. factor or factors.
