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 Iron Concentrate Particles will summarize the progress achieved in the last five years.

Our iron ore pellets and fines are made from magnetite and have high iron ore content 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 customers 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 customers ironmaking processes.

Tungsten is a metallic element with the symbol W and atomic number 74, belonging to the VIB family of the sixth cycle in the periodic table. Tungsten is mainly a hexavalent cation in nature, with an iron radius of 0.68 �? 10-10m. Due to the small radius of W6+ions, high electricity price, strong polarization ability, and easy formation of complex anions, tungsten is mainly in the form of complex anions [WO4] 2-, which combine with cations such as Fe2+, Mn2+, Ca2+in the solution to form precipitates of wolframite or scheelite. specification Diamter(mm) Tolerance Max length(mm) sintering,Forging,Spinning Forging and polishing 1.0-10 ±0.1 3000 10-20 ±0.1 2000 20-50 ±0.1 1500 50-70 ±0.2 1000 70-90 ±0.2 800 >90 Be customized

Mullite refractory castable general use of mullite aggregate to as raw materials and configuration of a kind of low temperature in the insulation refractories, it is commonly used in the petrochemical industry tube furnace, light diesel oil, ethane cracking furnace lining, atmospheric and vacuum furnace and sulfur recovery device and steam boiler, tortoiseshell net heat insulation layer, two barrel and pipe insulation monolayer, and other industrial furnace door, see the fire hole, observation hole door lining, etc. The advantage of mullite refractory castable is that its refractory temperature is higher than other thermal insulation castable, which can be directly in contact with the flame and used as the lining of the kiln. Another kind of refractory castable is corundum mullite castable, which is a refractory castable prepared with corundum as aggregate and powder plus some binder.It has higher mechanical strength and abrasion resistance than high alumina refractory and Mullite refractory, but less thermal shock resistance.
