Influence of Residence Time and Fine Grinding on PGMS

2015-3-16 · Long residence times are typical of the flotation plants because of the high value of the recovered material. A residence time greater than 60 minutes in the main stream of flotation is not uncommon [7]. The main purpose of this work was to investigate the possibility of PGM recovery by reducing the secondary cleaner tails grade to below 2g/t. A

2016-1-1 · The two extremes of residence time distributions are plug flow and fully mixed. For plug flow, all materials have the same residence time and hence the batch grinding equation is applicable when integrated from time zero to the residence time. The solution to this integration was originally proposed by Reid and is known as the Reid solution.
