Geochemical Analysis or Iron Ore

from raw iron ore samples by passing them through a number of furnaces with progressively higher temperatures. The LOI is a measure of the water content of the ore and an important step in iron ore analysis. When ore is fed into a blast furnace, the water contained in it will evaporate.

11.5 Refractory Manufacturing

2015-9-10 · 11.5.1 Process Description1-2 Refractories are materials that provide linings for high-temperature furnaces and other processing units. Refractories must be able to withstand physical wear, high temperatures (above 538°C [1000°F]), and corrosion by chemical agents. There are two general classifications of refractories, clay and nonclay.

Iron Ore | ScienceDirect

Iron Ore: Mineralogy, Processing and Environmental Issues summarizes recent, key research on the characterization of iron ores, including important topics such as beneficiation (separation and refining), agglomeration (e.g., production of pellets or powders), blast furnace technology for smelting, and environmental issues relating to its production.

The Steel Making Industry

Large, integrated steel mills with high capital costs and limited flexibility were built in the U.S. (Chatterjee, 1995). Integrated steel plants produce steel by refining iron ore in several steps and produce very high quality steel with well controlled chemical compositions to meet all product quality requirements.
