Heavy Minerals In Egypt
Mineralogy and chemical distribution study of placer …
Highly purified picked minerals of cassiterite and associated new recorded minerals were chemically and mineralogically investigated. Most of the investigated cassiterite exhibits homogeneous grains without obvious zoning. The analyzed cassiterites have more than 98 wt.% SnO2, which reveal clearly their considerable purity. Minor gold with traces of ferrotapiolite, …

Black sands in Egypt are beach placers deposited from the Nile stream reaching the Mediterranean Sea at river mouth. Floods associated with pluvial periods, which prevailed in Egypt during Pleistocene, may have caused erosion of the source rocks and liberated heavy minerals including monazite (Dawood and Abd El-Naby, 2007).
