Water-bentonite interaction in balling of iron ores ...

1973-8-1  Implications of these results in operation and control of industrial iron ore balling circuit are discussed. THE TONNAGE of iron ores agglomerated exceeded 100 million in year 1967 and is expected to touch 220 million mark by 1975 [1]. In most balling operations a small quantity, usually 5-15 lb/ton, of bentonite is added.

Balling and Granulation - ScienceDirect

1978-1-1  BALLING AND GRANULATION 57 In tonnage, by far the main application of balling is in the agglomeration of the run-of-mine iron ore dust and of the concentrates from low-grade iron ores. It is estimated that in 1976 the amounts involved are likely to exceed 200 million tons (R2).

Binding mechanisms in wet iron ore green pellets with a ...

2006-11-13  Micro-ballingIn the iron ore industry, small-scale balling is commonly called as micro-balling. Micro-balling was done in 7-kg batches of filtered material with about 6% moisture content. The moisture was adjusted in two steps. First, the moisture was adjusted 0.5% units below the target moisture content.
