RECOVERING METHOD OF HIGH CONCENTRATION NICKEL FROM WASTE ELECTROLESS NICKEL PLATING

The present invention relates to a method for recovering nickel from waste electroless nickel plating. According to the present invention, impurities are removed from the waste electroless nickel plating, an ion exchange resin to which nickel is adsorbed is prepared by removing an organic material and the like by using an ion exchange resin method, a nickel compound solution is obtained through acidic solution processing, the ion exchange resin is regenerated, and high-concentration nickel is recovered by repeatedly executing the same process by using the regenerated ion exchange resin and the nickel compound solution. According to the present invention, process expenses and costs can be saved compared to the existing nickel hydroxide preparation processes and expensive concentration processes such as that of an evaporation method using the existing solution concentration methods can be omitted. Accordingly, production costs can be saved and high-concentration nickel can be produced.
