Effect of fineness of grind on semi-batch flotation test

1/3/2005· Fig. 1 shows the effect of fineness of grind on the rate of flotation of Pb and Zn minerals and Pb grade–recovery curves for the Brunswick Mining ore. Results show that increasing fineness of grind from 60% to 99% finer than 0.038 mm (see Table 1 ) has little impact on the rate of flotation of galena but affects the recovery of marmatite.

Fine grinding of industrial minerals - Mineral Processing

The methods of preparing and processing these minerals differ greatly and essentially depend on the purity of the raw material and on the fineness requirements. Fine grinding is a process stage that is necessary for all industrial minerals, some of which have to be ground to the submicron range.

A method to predict metallurgical performances as a

1/10/1994· CONCLUSION A method is proposed to the predict metallurgical performances of a flotation plant as a function of the fineness of grind. The method uses empirical models to predict the size distribution of minerals for a given particle size distribution of the flotation feed.

Hegman gauge - Wikipedia

Determining the fineness of a paint''s grind is important, because too coarse a grind may reduce the paint''s color uniformity, gloss, and opacity. The Hegman gauge is widely used for this purpose because it requires minimal skill and only a few seconds'' work.
