EXTRACTION PROCESS

摘要

The invention relates to a method for the stabilization of the production capacity of an extraction plant extracting metals in a process, where the metal content of the feed solution varies. For the stabilization of capacity the extraction stages of the extraction plant are connected completely in parallel when the copper content is 2 g/l or below, and are connected partially or completely in series when the copper content is 2 g/l or higher, the extraction stages being located in two lines with a piping channel between the lines. The method is especially suitable for the copper extraction process.
