Method of dissolving-separating to absolute recovery nickel from wastes of nickel galvanization industrial

Abstract

The article describes the nickel recovery process by using dissolving method in order to dissolve alternately the hydroxide typed indissoluble ones fiom Nickel contained galvanization waste. The ICP-MS results show that, after some dissolving steps at room temperature the last one with boiling temperature at 100"C pernuts to recovery almost whole of nickel quantity. In this case the nickel recovery rate can reach up to 98.61%. Thus for better recovery efllciency theprocess should he rather conducted at 100"C than at room temperature
