Gaber, M. AW.
The Eastern desert possess a numerous natural ores with sufficient quantities can be ground to a very fine grain size and used as a component of decorative and protective paint materials necessary for protection of steel structure components. In this present study an investigation is carried out to search for the appropriate of local natural ores can be utilized in producing paint pigments, samples collected from different localities in the Eastern desert (Zafarana “Abu El Darag”, Um Greifat, Wadi Ghadir, Wadi Um Ghazal), the sample includes silica white sand, Iron oxide ‘Ochre”, Barite, Graphite. The collected specimens were crushed and ground to powder varying in size between “5 - 50 um” for laboratory testing. The evaluation techniques for the various ore samples incorporated laboratory work for measuring the material quality control together with laboratory testing including specific gravity, moisture content, pH value, oil absorption, X-Ray analysis, microscopic studies and others to prove that the selected local ores possess the required characteristics for pigments that can be utilized in producing the paint material in Egypt. The study indicates that the following local ore materials “Silica white sand of Zafarana, , Iron oxide of Um Gerifat, Graphite of Wadi Ghadir, and Barite of Wadi Um Ghazal ” can be utilized as extender and colored pigments to produce paint. The estimated reserves of the studded ores give an indication of presence the sufficient quantities for stream production of the some paint pigments needed for Egyptian market.
