    摘要： The invention relates to a method and arrangement for separating two solutions mixed in dispersion into two solution phases in a liquid-liquid extraction separation cell (1). The shut-off element (3, 4, 5) comprises a front panel (8) that extends along the whole width of the cell. The front panel (8) includes a bottom edge (9), which is arranged at a distance (H1, H2, H3) from the cell bottom (7), so that the front panel (8) allows an unobstructed flow of the heavier solution phase directly forwards underneath the bottom edge (9). In the vertical direction, the front panel extends to such a height that it forces the lighter solution phase placed on the heavier solution phase to flow as a thin overflow layer over the top edge (12) of the front panel (8) and forces the dispersion to thicken in front of the front panel. The rear panel (15) is essentially parallel with the front panel (8) and placed at a distance (S) therefrom, so that in between the front panel and the rear panel, there is formed an uptake shaft (14) extending essentially vertically upwards, along which uptake shaft the thickened dispersion can rise upwardly and be compressed. At least one slanting plate (16) is in the direction of the flow placed at an inclined angle (δ), inclined upwardly with respect to the horizontal plane. The slanting plate attenuates and slows down the vertical component of the rising compressed dispersion flow and guides the dispersion essentially in the lengthwise direction of the cell as a dispersion flow to the successive separator part.

    摘要： The invention relates to a method and apparatus with which an organic solution that is slightly soluble in water is scrubbed of aqueous entrainment and impurities. In particular, the organic solution may be the organic extraction solution of liquid-liquid extraction used in connection with the hydrometallurgical recovery of metals. The purpose is to perform the physical separation of water droplets and the chemical removal of impurities from the organic solution simultaneously. This occurs by routing the solution to be purified in the settling tank through at least one flow plate cassette of reduced cross-section.

    摘要： The invention relates to a flotation mechanism (4) comprising a directional element (25) and vertical vanes (26) located in a flotation cell (2). The directional element is symmetrical and is fixed at the center to the lower section of the hollow shaft of the mechanism. According to the corresponding method, due to the directional element (25), which is cylindrically inclined downwards from the outer edge the flotation mechanism directs the gas-slurry suspension that is formed in a downward slanting direction towards the side wall of the cell. The mineral suspension rises upwards from the side wall towards the center of the cell, from where the flow is diverted to the edges of the cell and the froth generated is removed from the cell. Using this flotation mechanism enables a powerful agitation, extending throughout the entire mixing zone (I).

    摘要： The invention relates to a method for extracting copper in liquid-liquid solvent extraction from aqueous solutions with a high sulphate content, by raising the viscosity of the extraction solution and by dispersing the aqueous solution into drops, achieving a dense drop aggregation. The viscosity of the extraction solution may be raised either by increasing the content of the actual extractant, the extraction reagent, in the extraction solution or by using a diluting agent with a higher viscosity than that of the diluting agent normally used. By raising the viscosity of the extraction solution the mixing durability of the extraction dispersion can be increased and resulting of that the amount of residual drops is decreased. Other advantages are that the extraction solution flow of the extraction process decreases in relation to the flow of the aqueous solution acting as the copper source and that the size of the extraction equipment needed is reduced.

    摘要翻译： 本发明涉及通过提高溶液的粘度并将水溶液分散在液滴中，从高含量硫酸盐水溶液中提取液 - 液溶剂萃取中的铜的方法，达到浓滴。 提取溶液的粘度可以通过提高萃取溶液中的实际萃取剂，萃取剂的含量，或通过使用比通常使用的稀释剂粘度高的稀释剂来提高。 通过提高提取液的粘度，可以提高萃取分散体的混合耐久性，并且导致残留液滴的量减少。 其他优点是提取过程的提取溶液流量相对于作为铜源的水溶液的流动而降低，并且所需的萃取设备的尺寸减小。
