Ferrous metals contain iron and may rust. Iron and steel can corrode – this is known as rust. Rust is a compound called iron oxide and is formed when iron and oxygen react in the presence of moisture or water. Most ferrous metals are magnetic. Name . two. types of protective layer that could be added to metal to help prevent rust. Metals and ...

These processes operate with different feedstocks. The BF-BOF pathway converts raw iron ore to pig iron and then to steel HM – while EAF converts both steel scrap and sponge iron to steel HM. DRI converts raw iron ore to sponge iron, a porous, permeable, and highly reactive product that requires treatment with EAF before selling to …

Pelletization is the process of making spheres of uniform quality iron ore with high carbon content. Iron ore is pelletized so that it can efficiently flow through a blast furnace for smelting. The process involves mixing iron ore fines with additives like limestone, dolomite, and bentonite. This mixture is then formed into balls on a balling ...

The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 …

Physical properties. Pure iron is a silvery-white metal that's easy to work and shape and it's just soft enough to cut through (with quite a bit of difficulty) using a knife. You can hammer iron into sheets and draw it into wires. ... Inside the furnace, the iron ore reacts chemically with coke (a carbon-rich form of coal) and limestone.

Siderite is both an iron ore and gangue mineral. Its principal economic value lies in its high iron content and the absence of process contaminants such as sulfur or phosphorous. It is part of a large group of isomorphous minerals, the calcite group carbonates, which share similar physical properties, and rhombohedral crystal form.

2. IRONPure iron is a metal It oxidizes readily in the presence of oxygen and moisture. In order to obtain metallic iron, oxygen must be removed from naturally occurring ores by chemical reduction. The properties of iron can be modified by alloying it with various other metals (and some non-metals, notably carbon and silicon) to form steels.
