Water content, overflowing fluidity and weight of entrained gangue particles in froths containing gangue were investigated, using MIBC, Yarmour F Pine oil, Dow Froth 250 as frothers in 500g Kyodaitype flotation test machine. Dry-grouned quartz and marble were used as gangue in the quantity of 100g/2.1-2.2l of solution. In the overflowed and sucked-in froths formed by use of Dow Froth 250 seemed to contain the least weight of entrained marble or quartz particles among the use of the three frothers. At the same time, the froth of the Dow Froth 250 showed the highest froth layer, and overflowing fluidity of this froth was the least. Explanation seems urgently needed to elucidate the relation between froth stability and the entrained gangue weight.
