Geochemical and mineralogical characteristics of some Gold mine tailings in the Eastern Desert of Egypt
The adverse environmental effects of mine tailings disposal on the surrounding ecosystems are worldwide environmental problems. Due to environmental issues related to tailings discharged on land surface, detailed tailings characterization is a prerequisite for a long-term management solution. The tailings from four gold mines in Egypt, namely Fatira, El Sid, Barramiya, and Atud were investigated for their geochemical-mineralogical features and ... Read more

Characterization and environmental impact assessment of gold mine tailings in arid regions: a case study of Barramiya gold mine area, Eastern Desert, Egypt.

Characterization and environmental impact assessment of gold mine tailings in arid regions: a case study of Barramiya gold mine area, Eastern Desert, Egypt.
Geochemical and mineralogical characterization and environmental impact assessment were performed on Barramiya gold mine tailings, Eastern Desert, Egypt. The Barramiya gold mine is situated within ophiolite decorated Nugrus suture zone, which composed of dismembered sequence of highly deformed and metamorphosed mafic to ultramafic rocks and their hydrothermal alteration products (carbonate rocks), interbedded with meta-volcano clastic rocks of the Nubian Shield. ...

Influence of climate, mineralogy and mineral processing on hardpan formation in two, low-sulfide, high- carbonate, Gold mine tailings in the Eastern Desert of Egypt

Influence of climate, mineralogy and mineral processing on hardpan formation in two, low-sulfide, high- carbonate, Gold mine tailings in the Eastern Desert of Egypt
Despite its importance within environmental management strategies, little concern is shown to sulfide oxidation and/or hardpan formation at neutral pH where dry condition prevails. Two gold mine tailings in Egypt, El Sid and Barramiya, were studied for their geochemical/mineralogical properties, and climate influence on hardpan formation. The tailings are characterised by homogeneous silt-sized sediments (>42%), have high carbonate, predominantly as ... Read more
