The oolitic hematite will be a potential source of raw iron ore for the Chinese iron and steel industry. Up to now, the oolitic hematite have hardly been utilized effectively by any single traditional technology. The direct reduction may be a practical technology for the exploitation of oolitic hematite. The results show that the metallization rate of the HeZhang oolitic hematite increases with both the partial pressure of CO increase and the reduction time lasted, and the maximum value of the metallization rate is obtained at 35% carbon monoxide in the N2-CO atmosphere and 4h reduction time at 1050°C with 10% calcium oxide in the oolitic hematite. The diffusion may be the primary factor controlled the metallization rate in the later stage of reduction.

The oolitic hematite will be a potential source of raw iron ore for the Chinese iron and steel industry. Up to now, the oolitic hematite have hardly been utilized effectively by any single traditional technology. The deep reduction assisted with microwave radiation may be a practical technology for the exploitation of oolitic hematite. The results show that the metallization rate can be obtained to 88.91%, and the iron recovery up to 90.70% for the oolitic hematite with an iron content 51.19%, when the deep reduction parameters are as follows, the reduction temperature is 1050°C, the residence time is 45min, and the ratio of reducing agent is 24%.

Iron Working

It is a well known fact that Brazil today is the greatest producer of iron and steel in all of Latin America. It is less well known that this industry is one of the oldest in the nation. Any effort to trace the development of this iron-working industry from its earliest sources should take into consideration the contributions of the Jesuits. As early as 1554, Father José Anchieta informed his Jesuit superiors and the king of Portugal of the existence of iron ore deposits in the interior of the captaincy of São Vicente (later São Paulo). Even more important in this respect was a forge established by the Jesuit Mateus Nogueira which in 1556 was instrumental in the manufacture of fishhooks, knives, wedges, shovels and other such implements used in the support of his community. These are claimed to be the first implements made from iron in Brazil.
