WhatsApp: +86 18838072829Iron 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 highquality product. Sintering and pelletizing are economic and widely used agglomeration processes to prepare iron ore fines/iron concentrate for ironmaking use.
WhatsApp: +86 18838072829For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.
WhatsApp: +86 18838072829Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is always preferred. Indian ...
WhatsApp: +86 18838072829Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
WhatsApp: +86 18838072829The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium to highgrade (+62% Fe) and are directly used in blast furnace and in directreduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and SteelVision, 2020).

WhatsApp: +86 18838072829Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.

WhatsApp: +86 18838072829Cliff's Tilden plant in Cleveland, USA, is the only iron ore beneficiation plant, where selective flocculation technique, using degraded starch as the flocculant, has been applied to produce pellet grade concentrate from a feed containing around 32% Fe . The plant has a capacity of processing 10 million tons and is in operation since 1975.
WhatsApp: +86 18838072829The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from Mta capacity to 28 Mta in the forthcoming years.
WhatsApp: +86 18838072829Abstract The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.
