Metal production, in particular iron and steel industry, is the dominant heavy industry in Ukraine. Ukraine is the world's eighth largest producer and third largest exporter of iron and steel (2007). Ukrainian iron and steel industry accounts for around 2% of worldwide crude steel output, 5% to 6% of the
The US iron and steel industry has paralleled the industry in other countries in technological developments. In the 1800s, the US switched from charcoal to coke in ore smelting, adopted the Bessemer process, and stone the rise of very large integrated steel mills. In the 20th century, the US industry successively
Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation. Slag, the byproduct of iron-working processes such as smelting or smithing, is left at the iron-working site rather than being moved
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent
Iron ore pellets and Pelletizing processes Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
