pecial importance in metallurg and electroplating when ion exchangers are used. The separation of metal salt solutions andlilcid without using additional chemicals is possible to certain extent without any actual ion exchan Theap li cation of this.method in the regeneration of pickling solutions and anodising ba#, as weIra, for the removal of undesirable secondary components which accumulate in electrolysis circuits in zinc recovery electrolysis, is explained'' documents compiled from experimental data; the possibilities of these methods are far from being exhausted. Preliminary investigations with soda-alkaline su ar solutions were carried out to extract and recover lead from material containing lead sulp%ate. The partial extraction of non-ferrous metals from municipal sewage sludge was carried out with the goal of deconcentrating only to the point where, after running through the process, the majority of the material is sufficiently decontaminated to allow agricultural use based on the new Sewage Sludge Application Directive. The concept for this type of process was devel- oped and tested on laborator scale, and pilot plant was subsequently erected. Althou he conomical recycling of the non?errous metals is probably not possible, the study of this su%jeci is important for metallurgy, because the process developed can save dislosal space which is urgently needed in the Federal Republic for the residues and sludges ich inevitably result from hydrometallurgical processes. 1 Joint project Duration: 0.0.8 - 2.0.8 0VQ2 Subject: Zinc production process with emphasis on environmental protection in cooperation with the lnstitut fur Metallurgie - Metallhuttenkunde - der TU Berlin Research centre: Forschungs- und Versuchsanstalt der KHD Humboldt Wedag AG Ottostrasse 1, 5 1 Koln Government sponsorship: DM 1,1 0 Sponsorship ratio: 4 0 Duration: 0 0 8 - 3 1 8 0 VQ2 Subject: Zinc production process with emphasis on environmental protection in co
