Flotation separation of barite from calcite using
#0183;#32;The above results suggest that flotation separation of barite from calcite can be realized when the AWG is used as a depressant for calcite. Hence, flotation tests of barite and calcite mixture with the mass ratio of 4:1 were performed in the present and absence of AWG using NaOl as the collector at pH 8, the result of which is shown in Table 2.
