Iron ores are the raw material used to make iron and steel. Iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries, such as China. As the content of iron ore in deposits has deteriorated, low-grade iron ore has been processed. Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a high-quality product. Sintering and pelletizing are economic and widely used agglomeration processes to prepare iron ore fines/iron concentrate for ironmaking use. The quality requirements of sinter and pellet, such as physical, chemical, and metallurgical specifications, depend on each ironmaking furnace, and those requirements influence the operation of the iron ore sintering and pelletizing plant. Researchers have usually focused on the effect of the chemical, physical, and mineralogical characteristics of iron ore on these steps and the consequences for sinter/pellet quality and sintering/pelletizing performance. The present Special Issue on â??Iron Concentrate Particlesâ?? will summarize the progress achieved in the last five years.
Pure sulfuric acid does not occur naturally due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air.[6] Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus, the reverse procedure of adding water to the acid should not be performed since the heat released may boil the solution, spraying droplets of hot acid during the process. Upon contact with body tissue, sulfuric acid can cause severe acidic chemical burns and even secondary thermal burns due to dehydration.[7][8] Dilute sulfuric acid is substantially less hazardous without the oxidative and dehydrating properties; however, it should still be handled with care for its acidity.
Our iron ore pellets and fines are made from magnetite and have high iron ore content â?? pellets at around 67 percent concentration and fines over 70 percent. This means they have lower impact on the environment than competing pellets and products such as sintered hematite fines. Using pellets instead of sinter (slightly larger pieces of iron ore) in customersâ?? pig iron processes saves emissions at steel plants. The high concentration of iron combined with the carefully tested and balanced additives in our pellets also result in lower emissions in customersâ?? ironmaking processes.
Prilled urea is a form of nitrogen-rich solid fertilizer that has the ability to dissolve quickly in water. Prilled urea is more commonly used today to resist breaking down when mixing with other fertilizer components like Potassium chloride. It is also known as ice melting or deicing urea since it can reduce ice efficiently, even at very low temperatures ( -6 â?¦C) .
A billet is a length of metal that has a round or square cross-section, with an area less than 36 in2 (230 cm2). Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. Billets are further processed via profile rolling and drawing. Final products include bar stock and wire. Centrifugal casting is also used to produce short circular tubes as billets, usually to achieve a precise metallurgical structure. They are commonly used as cylinder sleeves where the inner and outer diameters are ground and machined to length. Because their size is not modified significantly, they are not always classified as semi-finished casting products.

Urea is a raw material forthe manufacture of twomain classes of materials:urea-formaldehyde resins and urea-melamine-formaldehyde used in marineplywood. AGRICULTURE More than 9O% of world industrial production of urea is destined for useas a nitrogen-release fertilizer. Urea has the highest nitrogen con-tent of all solid nitrogenous fertilizersin common use. Therefore, it has the lowest transpor-tation costs per unit of nitrogen nutri-ent.
