Selective leaching of nickel from mixed nickel

Nickel recovery via ammoniacal leaching and SX presents two clear challenges; process sensitivity and impurity rejection. It is in these areas that selective acid leaching of MHP provides advantages. In this process as shown in Fig. 1, MHP is contacted with a strong oxidant and sulphuric acid solution.Scandium Recovery Process (Sumitomo Metal,The purpose of the present invention is to recover roughly purified scandium, which is purified to an extent acceptable for a technique for highly,Nickel | Dow Water & Process Solutions,Nickel is most frequently found in sulfidic ores and nearly always mixed with copper, cobalt, zinc, iron, and other metals. While solvent extraction (SX) can be used to recover nickel, novel selective ion exchange (IX) resins are making it possible to isolate and purify nickel at lower cost and in more environmentally sustainable ways.
