    Abstract: Two strategies have been chosen for the exploitation of El-Gedida high-Mn iron ore containing 46.37 wt.% Fe and 7.53 wt.%Mn. The first one included magnetic roasting and subsequent low intensity magnetic separation. The second strategy involved a blend process of the El-Gedida high-Mn iron ore with the Um Bogma manganese ore. The magnetic separatio... Show More

    Abstract: The free convections of the fluids water and air over the globe lead to evaporation of water and generation of winds, respectively. Heinrich Hertz and M King Hubbert both assign 40000∙1012W solar power for evaporation of water and subsequent annual rainfall of around one meter over the globe. However, Hertz has mentioned two estimates 400∙1012W and... Show More
