Bentonite Iron Ore Pelletization

Bentonite is a predominant binder used in iron ore pelletization. However, the presence of a high content of silica and alumina in bentonite is considered undesirable for ironmaking operations. The objective of this study was to identify the alternatives of bentonite for iron ore pelletization. To achieve this goal, different types of organic and inorganic binders were utilized to produce iron.

    Bentonite clay has traditionally been the most common binder for iron ore pelletizing. It however contaminates the product with silica and other undesirable elements, thus lowering the iron content [5] and adding additional material to the process. Addition of 1 bentonite.The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions.

  • Effectiveness Of Organic Binders For Iron Ore Pelletization

    Effectiveness Of Organic Binders For Iron Ore Pelletization

    Iron ore must go through a lengthy pre processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.Anew kind of iron ore pellet binder named humic acid modifying bentonite (HA MB) has been developed by the author's group, which has the advantages of both organic HA and inorganic bentonite. The green pellet strength can be obviously improved by using the HA MB binder. In this study, the detection of the characterization of HA MB was conducted by zeta potential, TG DSC, FTIR, XRD, etc.
