Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and

Iron ore and other iron bearing materials, coke and limestone are charged into the furnace from the top and work their way down, becoming hotter as they sink in the body of the furnace. In the top half of the furnace, gas from burning coke removes a great deal of oxygen from the iron ore. About halfway down, limestone begins to react with impurities in the ore and the coke to form a slag. As

Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace. Sinter feed composition control is important because the various sinter feed materials are not perfectly characterized and their chemical makeup varies within a batch and between batches.

Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin.

Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.

Equipment for Iron Ore Sintering Process and Steel Sinter is the primary feed material for making iron in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast

2 is used to reduce iron ore pellets to "direct reduced iron" (DRI, or sponge iron). The reaction takes place in a shaft furnace, a type of furnace that uses gas reductants to make DRI. The operating temperature can be fairly low, around 800°C. The DRI is then fed into an EAF and turned into steel by further processing it and adding carbon. As
