“…The Egyptian black sand along the Mediterranean coast comprise huge reserves of several common economic minerals. The Rosetta black sands have been the subject of many articles and dissertations, as well as technical reports by private firms [9].Beach sand deposits are mostly rich sources of industrial minerals [10]. Phosphate rocks of sedimentary origin contain 238 U and 232 Th and its decay products in addition to phosphate minerals .…”

The rare earth elements (REEs), uranium (U) and thorium (Th) isotopes found naturally in soil, rock, water and plant. About 20 samples of Black sand and phosphate were collected from different locations in the Rashid city , Egypt. All the collected samples were prepared and chemically treated using different acids and microwave, then analyzed using ICP-MS. The present work was conducted to identify and evaluate the compositional trends of REEs, U and Th in the samples in terms of distribution patterns and indicator ratios. The results revealed that the black sand and phosphate ores are rich as natural sources of U, Th and other rare earth elements. The elements' concentrations in black sands and phosphate ores were found higher than the world average crust soil.

“…TiO 2 exists in the form such as anatase, rutile and brookite minerals. 5 Various methods have been used for determining titanium content in different types of samples, such as: inductively coupled plasma-atomic emission spectrometry (ICP-AES), 6 inductively coupled plasma-mass spectrometry (ICP-MS), 7 graphite furnace atomic absorption spec-trometry (GFAAS), 8 catalytic adsorptive stripping voltammetry (CASV), 9 neutron activation analysis (NAA), 10 spectrophotometry, 11,12,13 X-ray fluorescence (XRF), 14 and laser induced breakdown spectroscopy (LIBS). 15 Chemical composition of bauxite is usually expressed in the content of Al 2 O 3 , SiO 2 , Fe 2 O 3 , TiO 2 , and CaO, with the loss on ignition at 1075 °C.…”

Bauxites of different deposits were analysed for their content of TiO2 (mass %), using X-ray fluorescence spectrometry and the reference spectrophotometric method JUS B.G8.514. The samples were prepared in two ways: fusion with a borax technique and pressing, after which beads were formed for the purpose of analysis. Certified reference samples of bauxite were used for producing a calibration curve. The equation for calculating the content of TiO2 (mass %) in the samples of bauxite was derived from the calibration curve. Results of the XRF method were tested statistically by means of the F-test and the t-test (the standard sample of the bauxite and the reference method). The values obtained from the afore mentioned tests for the fusion beads showed that the XRF method was precise and correct and that there were no systematic errors, whereas for the pressed beads this method showed significant systematic errors.

“…The most significant of these are the ilmenite ± zircon ± hematite ± vesuvianite ± monazite ± rutile ± corundum Jreida-Lemsid placer deposit of Mauritania (Markwitz et al 2015), and the black sand deposits of the northern Mediterranean coastal plain of the Nile Delta and Sinai Peninsula in Egypt (Hedrick and Waked 1989;Dawood and Abd El-Naby 2007). It is noteworthy that the Egyptian black sand deposits constitute huge reserves of ilmenite, magnetite, garnet, zircon, rutile, and monazite (Mahmoud et al 2013). Beside these coastal beach accumulations, eluvian and alluvial placer deposits in Egypt, Sudan, Niger, Mali, and Mauritania have been worked since Predynastic (ca.…”

Mineral Deposits of North Africa

North Africa is noteworthy for having a great diversity of geology and mineral resources. Geologically, the region contains numerous terranes that contain rocks ranging in age from Archean to Quaternary, including diverse igneous, sedimentary, and metamorphic lithologies. Major geological features were built during the main phases of Proterozoic and subsequent Phanerozoic orogenies, the break-up of the supercontinents Rodinia, Gondwana, and Pangea, and during the opening and closing of major ocean basins such as the Iapatus, Atlantic, Pacific, and Tethys. Three major tectono-stratigraphic domains are recognized (1) the Precambrian province that includes the African-Nubian Shield (ANS) to the east and the West African Craton (WAC) to the west, and the intervening Tuareg Shield and "Saharan Metacraton"; (2) the Variscan (Paleozoic) fold belt; and (3) the Atlas-Alpine (Mesozoic-Cenozoic) system. Mineral deposits of North Africa formed in a variety of geologic settings at different time periods from Archean to Quaternary. Mineral commodities including gold, silver, cobalt, nickel, chromium, arsenic, copper, lead, zinc, iron, and many other elements. Major deposit types present in the region are (1) orthomagmatic Cr-Ni-platinum group elements (PGE); (2) rare-metal granites and related rare-element pegmatites; (3) volcanic-hosted massive sulphide (VHMS); (4) sedimentaryexhalative (SEDEX); (5) orogenic and intrusion-related gold; (6) iron oxide-copper-gold (IOCG); (7) banded iron formation (BIF); (8) Mississippi Valley-type (MVT) lead-zinc; (9) sediment-hosted stratiform copper;Electronic supplementary material The online version of this chapter
