The high financial investment and risk associated with any mining project and the ever stricter environmental and social controls were the forces behind this recognition. For years the industry experienced the development and enforcement of...

Hot-pressed aluminium and silicon coated boron steel is used in the car industry where high tensile strength is of great importance, such as in the safety cage of a car where deformation has to be kept to a minimum in case of a collision. After hot-pressing the AlSi-boron steel shows excellent properties with high tensile strength, minimal spring back and also shows good protection against corr...

The article analyzes the place of China in world market mining resources. It is shown that not only a leading producer metallurgy resources, but also plays unique role as world's main importer such global industry has high concentration, so no more than ten countries export metallurgical resources to China. occupies significant equipment for industry. In last decade, country become one exporter...
