Hematite Grindability Test India

Comparative Analysis of Grindability of Iron

· Smith and Lee in 1968 used batch­type grindability tests which conformed to the result obtained when work indices from the standard Bond test was used The batch­type test compares favourably with the advantage of less time consuming Berry and Bruce 1966 developed a comparative method to determine the grindability of an ore The method requires the use of a reference ore of
