· Abstract The characteristics of mineral floatability, namely, the wetting angle and the induction time, are examined. The agreement between the predicted floatability using these characteristics and the theoretical and experimental data is accessed. It is found that hydrophobicity defined by the wetting angle is not always a quantitative

A flotation machine is a piece of equipment used in ore processing to separate valuable minerals from the ore using the principle of bubble flotation. During the flotation process, the ore is crushed and suspended in a water tank. Then, by introducing bubbles and specific reagents, the valuable minerals attach to the bubbles, float to the water
