Flotation : a study of some conditions for selective flotation (English)
Abstract [en]

The zeta potential for oxide- and silicate minerals has been measured in different pulp liquids and a comparison has been made concerning the results of the flotation. The results show that the surface charge of the mineral particles reflect the condition of the dispersion of the pulp, and guiding the surface charge is a way of increasing the selectivity when concentrating by flotation. The results also show that the zeta potential indicates how easily amino reagents are adsorbed on silicate minerals. A successful dispersion is a condition for good selectivity with the exception of selective flocculation. Selective flocculation can be used in flotation in a case of for example quartz flotation with amine as the collector, the iron mineral being flocculated with dextrin. An example is given of selective flocculation of baryte and flotation of baryte.
