摘要： Selective extraction of zinc from chloride solutions which contain iron, copper and zinc, where the zinc is extracted in organic phase by means of tri-n-butylphosphate in an organic solvent. The extraction is carried out on chloride solutions in which the lead contents is possibly lowered and where the copper contents is maximum 50 grams per liter higher copper concentration being reduced for instance by electrolysis in diaphragm cell. The zinc containing organic phase is washed, and zinc back-extracted and conducted to a diaphragm cell for electrolysis of zinc, the used electrolyte being returned to the back-extraction step. The raffinate from the zinc extraction is used for repeated leaching of metals after preceding reoxidation.

摘要： The present invention relates to thermoplastic resin compositions, particularly polyolefines, polyvinylchloride and polyamide. The thermoplastic resin compositions contain between 3 and 400% by weight of filler based on the weight of the resin, said filler comprising talc and microsilica where the weight ratio between talc and microsilica is between 15:1 and 1:15. The invention further relates to a method for the production of thermoplastic resin compositions, and to a filler blend for use in thermoplastic resins, said blend containing talc and microsilica in a weight ratio between 15:1 and 1:15.
