agglomerate of iron ores
Correlating chemistry and mass transport in sustainable iron
In this work, we directly measure the connection between chemistry and agglomeration in the smallest iron oxides relevant to magnetite ores. Using synthesized spherical 10-nm magnetite particles reacting in H 2, we resolve the formation and consumption of wüstite (Fe 1-x O)-the step most commonly attributed to whiskering.

The Effect of Concentrate/Iron Ore Ratio Change on Agglomerate …
The disadvantage of the iron ores used iron ores is their very low alkalinity, which directly affects the richness of the resulting agglomerate. Another batch component is iron ore concentrate. Only one sort was used in the experiment to replace some part of the concentrate with tested iron ore (AR-5).

Metallurgy through the Ages | Encyclopedia
Iron began to replace bronze in about 1200 b.c. Iron oxide was used as flux in the smelting of copper to help the metal agglomerate. As temperatures in kilns were raised to accommodate new ores, this flux would leave iron residues. The first smelting of iron probably occurred in Anatolia, part of modern Turkey, in 2000 b.c.
