Conclusions

A two-stage extraction process for regenerating zinc from wash water in the manufacture of viscose fibres has been worked out on a pilot set-up.

Two types of extraction equipment have been tested — a vibrating column extractor and a mixing-settling extractor. Figures have been obtained for the efficiency and output of these extractors; these figures are necessary for designing industrial apparatus.

The vibrating column extractor is recommended for apparatus design of the extraction stage; the mixing-settling extractor, for the re-extraction stage.
