Three important aspects of mineral-beneficiation practice, viz batch grinding on a laboratory scale, classification, and gravity separation, were analysed in a determination of the effect of a grinding aid made by Dow Chemicals, XFS U.272.00, on each of their respective process environments. For the batch-grinding environment, it was found that fairly severe process conditions (a pulp density of 85 per cent solids, grinding aid at a concentration of 2 kg/t, and a grinding time of 30 minutes) were necessary before significant increases were achieved in the grinding rates. These process conditions produced an average increase in the fineness of the product of 4,7 per cent. The effect of the grinding aid on classification was studied by the passing of the pulp, in turn, through 25 mm and 50 mm hydrocyclones and a 150 mm spiral classifier, different additions of grinding aid being used in each case. The results showed that there was a tendency for the uncorrected cut size to reduce slightly, and for the sharpness of particle classification to improve marginally when the aid was introduced. Closed-circuit tests with a spiral concentrator showed that dosages of between 50 and 300 g/t improved the grade and recovery of concentrate, but that, at dosages of 500 g/t, the grade and the recovery began to decrease.

The History Of Grinding written by Alban J. Lynch and has been published by SME this book supported file pdf, txt, epub, kindle and other format this book has been release on 2005 with Technology & Engineering categories.
An in-depth examination of the oldest engineering process, The History of Grinding begins at the start of agriculture and outlines how size reduction developed over the centuries(without completely immersing the reader in technical detail). Great technical achievements have led to the machines of today, which can grind solid particles at the rate of tens of thousands of tons per day. One certainty is the existence of the continuing need for size reduction to develop and fit the lifestyles of people both today and in the future. Photos and illustrations gleaned from numerous sources, a glossary, reference list, and index enhance the text. Chapters include Size Reduction from the Stone Age to the Space Age; The Science and the Scientists; Hand Stones; Water Wheels, Windmills, and Beyond; Stamp Mills and Crushers; Roller Mills; Tumbling Mills; Fine-Grinding Mills; Classifiers; Explosive Rock Breakage; and Size Reduction in the 21st Century.
