The Making of Iron Steel

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as gangue. The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent. The metallic iron produced by such a furnace contains a relatively high proportion of carbon (4%

Geochemistry of Archaean volcanic rocks from Iron Ore

The high-MgO components in both the groups are suggested to represent high degrees of melting compared to the basalts in each group. It is further suggested that the tholeiitic basalts have been generated relatively early from a chondritic source. Down-buckling of this material has added LREE enriched melts to the source, thereby changing its character into a LREE enriched one. Melting of a

carbide (Cr,Fe)7C,. Thus, an ore rich in iron oxide will have high reducibility at relatively low temperatures 171. Accordingly, the reduction of chromic oxide in such ores will also occur at relatively lower temperatures with the likely formation of a carbon-rich chromite carbide (Cr,C, or Cr7C3) known to be stable at lower temperatures. The gangue present in a chromium ore has a significant
