| 摘要 | An arrangement for recirculation of flotation gas in a mineral flotation process wherein the flotation gas volume fluctuations are handled by a closed pressure equalization loop including an apparatus for storing gas and adsorbing changes of gas pressure; a flushing line for connecting the pressure side of the primary gas recirculation loop to the apparatus for storing gas and adsorbing changes of gas pressure for allowing expulsion of a fraction of the flotation gas from the primary gas recirculation loop; and a suction line for connecting the suction side of the primary gas recirculation loop to the apparatus for storing gas and adsorbing changes of gas pressure, whereby the suction line comprises a pressure reducer for restricting flotation gas flow through the suction line. | ||||||
