A review of binders in iron ore pelletization Mineral

Oct 26 2010The most common agglomeration technique is pelletization which requires the use of binders to hold the iron oxide grains together so that the agglomerates can be sintered into high-strength pellets Although bentonite clay is the most commonly used binder there are many other possibilities that could be competitive in a number of situations Get price



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 % bentoniteGet price
