depression carbonate depression in flotation

: Effect of depressants in the selective flotation of ...

2019-1-21 one of the major sources of zinc carbonate ores. Both smithsonite and calcite are calcite-group minerals which are isomorphous with one another (Kaspar, 1959). In general, flotation is the common method for the separation of smithsonite from calcite due to their relatively similar physical properties (Irannajad et al., 2009).

: Flotation separation of carbonate from sulfide

Solution chemistry, zeta potential and Fourier transform infrared spectroscopic measurements were performed to study the mechanisms of selective depression of sulfide minerals by thioglycollic acid/citric acid during the flotation of carbonate minerals by sodium oleate. It was observed that the addition of the mixed depressants (thioglycollic acid and citric acid) removed active sites from ...

: Effects of sodium carbonate and calcium chloride on ...

2017-8-1 The flotation experiments and contact angle measurements indicated that the selective depression effect of sodium carbonate on the calcite mineral is more than that of calcium chloride. As evidenced by zeta potential and FT-IR analysis, sodium carbonate decreases the negative charges on the surface of calcite mineral and subsequently reduces ...

: Use of depressants in the direct flotation of a silicate ...

1. Introduction. Flotation is the most common concentration process used by the mineral industry, both in quantity of ores processed and in diversity of applications (Peres et al, 2007).At present, over 2 x 10 9 t per year of ore is estimated to be processed through flotation. In Brazil, this technique played an important role in the growth of the mineral sector, especially in the industry of ...
