    摘要： The invention relates to a method of clarifying and/or thickening a solution containing solids i.e. a slurry, and the apparatus for accomplishing this. Using the method and apparatus of the present invention, the flocculant to be fed into the clarification and thickening equipment is mixed evenly and with a small shear force into the slurry in the feedwell of the apparatus. The feedwell is equipped with a mixing device. The slurry is taken onwards from the feedwell evenly into the clarification tank inside the underflow layer, which enables the separation of a clear overflow solution.

    摘要： The invention relates to a method and equipment with which an organic solution extraction solution is purified from entrainment of aqueous solution and impurities during hydrometallurgical liquid-liquid extraction. The method treats an organic extraction solution, which is loaded with a valuable metal or valuable substance from the aqueous solution. The extraction solution is scrubbed with an acidic aqueous solution. The acidic solution is discharged into the tank in several separate sub-streams. The flow diverts from horizontal to vertical and the direction of the separated solutions is deflected by means of picker fences (13, 14). The organic solution and the aqueous solution are removed in separate sub-streams. A settler comprises several discharge elements (12) for organic solution and suction elements (16, 24) for removing organic solution and aqueous solution respectively.

    摘要： A quench system for cooling and/or cleaning metallurgical gases which are guided cocurrently with an acid-containing liquid, in particular sulfuric acid, includes a gas inlet (51) through which the gases are supplied from the top, an annular channel (55) extending about the inner circumference of an upper Venturi portion (52), over whose inner overflow wall (57) the acid-containing liquid flows over into the upper Venturi portion (52), and lateral nozzles (58) provided below the annular channel (55), through which additional acid-containing liquid is introduced. To obtain a clear separation between wall portions of the Venturi portion exposed to dry/hot or wet/cold conditions, the inside diameter (D1 ) of the upper Venturi portion (52) is greater than the inside diameter (D2) of the gas inlet (51), in accordance with the present invention.

    摘要： The invention relates to method for leaching zinc-containing materials in connection with the electrolytic recovery of zinc. According to this method, the feed materials i.e. zinc calcine and zinc sulphide, are leached in three stages, in which he sulphuric acid content of the stages rises in accordance with the direction in which the solids are moving. The solids and solution formed in the leaching stages are routed throughout the process countercurrently in relation to each other.

    摘要： A pulp lifter for installation in a grinding mill has a leading edge and a trailing edge with respect to rotation of the mill and comprises a first wall bounding an interior space and a second wall dividing the interior space into first and second sections. The first wall includes a leading edge wall formed with an inlet opening providing access to the second section and an inner edge wall formed with an outlet opening for discharge of slurry from the second section. The second wall includes a guide that extends substantially from an outer end of the leading edge wall to a trailing end of the inner edge wall, and the first section of the interior space is open at the trailing edge of the pulp lifter.
