摘要： The invention relates to a method for separating the impurities zinc, iron, calcium, copper and/or manganese from aqueous solutions that contain cobalt and/or nickel. An aqueous solution (1) containing metallic salts is brought into a mixing contact with an extraction solution (2), which is pre-loaded with cobalt and/or nickel ions, whereby the cobalt and/or nickel in the extraction solution are replaced with the impurity metals, and the aqueous solution is cleaned from impurities after this phase. This purified aqueous solution, raffinate (3), can be used to pre-charge the extraction solution with cobalt and/or nickel ions, so that a minor part (5) of the raffinate is contacted with a pre-neutralized extraction solution (6), whereby the cobalt and/or nickel replace the alkali metal, alkali earth metal or ammonium ion that is used in the pre-neutralization. After this pre-charging stage, the aqueous solution that contains said alkali metal, alkali earth metal and/or ammonium ion, but no cobalt and/or nickel, is conveyed as reject (7) out of the process. After the extraction stage, the extraction solution (8) can be washed at a separate washing stage with washing water (9) that contains impurity metal chlorides. In that case, the cobalt and/or nickel ions remaining in the extraction solution are replaced with the impurity ions and they transfer to the chloride-containing aqueous solution. This washing water (11) can be conveyed to the pre-charging stage mentioned above, whereby the chloride ions that come along are removed to the reject. After the washing stage, the impurities can be back-extracted into the aqueous solution by the aqueous solution (13) of hydrochloric acid.

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。
