Applied Geological Studies of Some Sinai, Egypt Ore Deposits to Utilized as Extender Pigments for Paint Manufacture
The collected specimens were crushed and ground to powder varying in size between “5-50 um” for testing using laboratory mill.
Several laboratory tests were accomplished to identify and evaluate the decorative and protective paint pigment 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 ores can be utilized as extender pigments to produce paint materials “calcium carbonate of south Sinai, white sand of Um Bogma, and gypsum of Ras Malaab.
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.
