Method for obtaining standardized alloys of copper and aluminium from metallic fractions obtained from reworking of WEEE or Cu and Al. cables

摘要

The method of obtaining standard copper and aluminium alloys from metallic fractions from the conversion of the SEE by low temperature pyrolysis in the nitrogen atmosphere at 500-650-C temperature and melting in the induction furnace or cable Cu and Al after mechanical conversion is characterised by this, that the solid popyrolic fractions were held in a ball mill, undergoes magnetic separation, and then the pure metal fractions so separated with metal content at least 95% undergo induction conversion at a rate. 850-1500-C and then pours into the form of goose or granules,it compares the pre-brake thus obtained with the standard rates and corrects the pre-brake composition by adding the missing mechanical components until the composition corresponding to the chemical composition of the standard rate is obtained.
