    摘要: The invention relates to a process for the froth flotation of complex ores. In accordance with this invention, froth flotation is carried out by using a collector and froth flotation conditions for which it has been calculated in advance that the said mineral and the collector form stable surface compounds. The conditions include the electrochemical potential of the system, the concentration of the collector, the pH, and other physical factors. According to this invention it has been observed that by adjusting the potential and the concentration of the collector separately for each mineral, each mineral can be frothed out separately from the slurry, the process being in this case specific for the mineral. When so desired, the different minerals of the ore slurry can also be frothed simultaneously by selecting the conditions where the Pourfaix-type diagrams of all minerals in said complex ore overlap under the conditions in question.
