study of petroleum coke used as reducing agent in iron ores

A petroleum coke with a high sulfur content (approximately 7.0 wt %) was tested as reducing agent in iron ores processing. Proprietary TECNORED pellets were prepared by blending of iron ore fines, petroleum coke fines and other additives (binders, fluxing agents, etc.) through a wet- pelletizing process. A pilot-scale.

Recycling of steel plant mill scale via iron ore sintering plant .

During the processing of steel in steel mills, iron oxides will form on the surface of the metal. These oxides, known as mill scale, occur during continuous casting, reheating and hot rolling operations. Mill scale is a valuable metallurgical raw material since it contains 65–70% iron. JSW Steel Ltd is a 7 Mtpa integrated steel.

Steelmaking - Wikipedia

Steelmaking is the process for producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce different grades of steel.
