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).

For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color. This is because the froth is becoming purer as
