METHOD FOR TREATING A SOLUTION CONTAINING ZINC SULPHATE |
摘要 |
The invention relates to a method for treating a solution containing zinc sulphate, so that at least one of the rare metals such as indium, gallium and germanium can be separated from it. A portion of the metals to be separated can be precipitated from zinc sulphate solution by neutralizing the acidic solution and at least a portion is cemented by means of metal powder. The solid precipitates that are formed can be combined and treated subsequently in some suitable way to leach out the desired metals. |
