  Review of hydrometallurgical recovery of zinc from industrial …

  200181 · In this paper, a review has been made for the recovery of zinc from the different secondaries/wastes containing zinc using different lixiviants. Usually, sulphuric acid, hydrochloric acid, ammonia/ammonium carbonate, ammonium chloride, caustic soda, carboxylic acid etc. are used as lixiviants for the dissolution of zinc.

  A simple and rapid method for isotopic analysis of nickel, …

  2017515 · Stable isotope ratios of nickel, copper, and zinc are powerful tools for elucidating the biogeochemical cycling of trace metals in the ocean. However, analytical difficulties have impeded isotopic studies of these metals. We present a simple and rapid method for simultaneous analysis of Ni, Cu, and …

  Selective Extraction of Ni from Superalloy Scraps by Molten …

  2021621 · Bearing significant concentrations of high value and critical metals, superalloy scraps require comprehensive recycling for metal reclamation. In this study, nickel-based superalloy was treated with molten Mg-Zn for the selective extraction of nickel. The influence of heating temperature, the molar ratio of Mg to Zn in the molten metal, Mg …

  Solvent extraction process for the recovery of nickel and …

  201751 · Highlights • A two-sequential solvent extraction circuits allows nickel and cobalt separation. • 94% Ni and 91% Co are totally separated from the feed solution. • 20 g L −1 of cobalt salt solution is effective to remove co-extracted impurities. • The first bench scale solvent extraction flowsheet is proposed for Caldag laterite leach solution.

  Solvent extraction separation of zinc and cadmium from nickel …

  2000101 · Great success has been achieved in Norway with solvent extraction separation of cobalt and nickel [2]. Cobalt forms more stable anionic chloride complexes than nickel in the strong chloride solutions used in the plant. Selective removal of cobalt using triisooctylamine can therefore be achieved.

  Removal of Nickel from Electroplating Wastewater by a …

  2023815 · Abstract The electroplating industry generates wastewater and solid waste with diverse compositions and numerous components. Different chemical compositions and low concentrations of heavy metals both in solid wastes and in waste and washing waters make it necessary to develop treatment technologies for almost every type of wastewater. …

  Separation of cobalt and zinc from concentrated nickel …

  2010913 · McCabe–Thiele diagrams were constructed to determine the theoretical extraction and stripping stages and a flowsheet to separate cobalt and zinc from nickel was proposed. With this flowsheet, more than 99% cobalt and zinc could be separated, resulting in a pure nickel solution with less than 10 mg L −1 of cobalt and zinc.
