Probable mechanism of the operation of the flotation pulp density on the selective flotation of the sulphide minerals
(2006) Petrova, Hristina; Boteva, Antoaneta
In this report it's looked through the problem about the research of the possibilities, by the change of the solid phase content in the pulp for improvement of the flotation process selectivity during the flotation of the multicomponent ores. It's searched for the relation between the lessened aeration in the conditions of the flotation with higher density of the flotation pulp and the competitive struggle between the main sulphide minerals which differ theirselves of it's hydrophobic mineral surface and of the processes, running in the three-phased froth as well. The results of the research indicate that the increased density doesn't always lead to the decrease of the process of selectivity. It's found that the rising of the solid phase content in the pulp up to a definite limit improves the selectivity of the process, but it can hardly get worse above this limit. The limit is most likely to be different for the different technological cases, but it's obviously to be always available.
