In this process, 150 g/t of KAX and 50 g/t of MIBC were used as a collector and frother, respectively. Scheelite rougher flotation was carried out using the remaining pulp with suspended sulfides, such as pyrite,Selective flotation of scheelite from calcium minerals,,01/04/1983· Selective flotation of scheelite from calcium ores is more difficult. In general, by floating the crude ore with sodium silicate and fatty acids, a scheelite-calcium mineral {such as calcite, fluorite, etc.) bulk concentrate is obtained. There are then two cleaning processes for treating this concen- trate: (1) In the U.S.S.R., the conventional cleaning process is the Petrov's process which,
