Unfortunately, there are no satisfactory methods available for accurately predicting which bentonites are actually most effective, short of using them to actually make pellets. One of the popular methods for attempting to evaluate bentonites is the …
This paper seeks to confidently prove that PWA can be used to accurately determine the efficacy of starch binders both alone and in conjunction with bentonite. The role of bentonite as a binder for iron ore concentrate is not only to hold agglomerates together during high temperature operations.

the relationship between the bentonite PWA value and the dry compressive strengths ofiron ore pellets. Pellet strength correlated poorly with the standard PWA test results, where bentonites are allowed to absorb distilied water for 18 hours. Correlations improved, but remained marginal, when PWA was measured in

The plate water absorbance (PWA) value of a bentonite is measured by a laboratory test to determine water absorbency of bentonite. The test determines how much water is absorbed by 2.00 g of bentonite, expressed as a percentage of the bentonite weight.
In this study, experiments were conducted to determine the relationship between the bentonite PWA value and the dry compressive strengths of iron ore pellets. Pellet strength correlated poorly with the standard PWA test results, where bentonites are allowed to absorb distilled water for 18 hours.
Plate water absorption has been traditionally used to assess the binding ability of bentonite clay binders for iron ore concentrate pelletization. Until 1997 there was an accepted test by...
Current tests of bentonite effectiveness include plate water absorption (PWA), methylene blue uptake,free swell, exchangeable cations and glycolated layer expansion. However, these tests have many disadvantages.
