Extraction and Refining of the Platinum Metals
The dissolving of the nickel anodes follows the same general pattern, the products being pure nickel cathodes and an anode slime containing the bulk of the platinum group metals. In this case the electrolyte is a neutral solution of nickel sulphate containing boric acid as a buffer and has to be continually purified to produce a pure cathode.Web
