摘要： The invention relates to a method for controlling a process operating by means of the electrochemical potential, in which process complex ores and/or concentrates are treated in order to arrange the valuable components in the materials in a form appropriate for further processing and in which method electrodes made of material essentially similar to the materials to be treated in the process. According to the invention an impedance analysis in connection with the measurement of the electrochemical potential is carried out for the material to be treated in process in order to analyze the state of the solid surface and/or the state between the solid material and the intermediary material. The measured values are utilized in the adjustment of the process parameters. In order to carry out the impedance analysis voltage pulses are conducted into the material in at least one frequency and in at least one value of the electrochemical potential of the material.

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.

摘要： The invention relates to a process for the recovery of valuable metals from sulfidic, silicate-containing raw materials by slurrying the raw material in water, by subjecting the slurry to a selective leach under atmospheric conditions and in an acidic milieu, and by separating the valuable-metal containing solution from the solid leach residue.When the leach is carried out by introducing an oxygen-bearing gas into the slurry which contains finely-divided sulfide and carbon, the acidity of the slurry drops in a controlled manner so that a high efficiency of oxygen, and a high selectivity of the leach as regards valuable metals, are obtained. Owing to the presence of carbon the oxygen is reduced very easily and so oxygen efficiency is high and the rate of dissolving of the valuable metals increases in the slurry mixture.
