basalt used as iron ores
Metal transports and enrichments in iron depositions hosted in
2015年12月1日 This study focuses on revealing the mechanism of metal transport, enrichment and Fe origin of iron deposition during water basalt interactions occurred in Compared to granitic rocks exposed at the Earth's surface, basalt outcrops weather relatively rapidly. This reflects their content of minerals that crystallized at higher temperatures and in an environment poorer in water vapor than granite. These minerals are less stable in the colder, wetter environment at the Earth's surface. The finer grain size of basalt and the volcanic glass sometimeBasalt - Wikipedia2018年10月5日 Our results reveal complex lithological, textural and geochemical variations characterized by magmatic-like features and, most notably, a systematic increase in Formation of massive iron deposits linked to explosive volcanic ...
Geochemistry of a komatiitic, boninitic, and tholeiitic basalt ...
2013年1月1日 Ultramafic (komatiitic) to mafic (basaltic) volcanic rocks (typically distinguished by a MgO content of higher and lower 18 wt.%, respectively), interlayered Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is Iron processing - Ores, Smelting, Refining BritannicaIron ores [1] are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron Iron ore - Wikipedia
