Abstract
Procedeu de recuperare a elementelor utile din zgurile rezultate în pirometalurgia cuprului prin topire în amestec cu 2....6% praf de cocs si eventual, 5....15% pirita aurifera, în cuptor electric cu arc, la 1400....1500 degree C, mentinînd topitura timp de 30 min, la 145 degree C pentru volatilizarea Zn si Pb, urmata de mentinerea, în continuare timp de 25 min, în intervalul de temperaturi mentionat pentru matificarea cuprului si eventuala trecere în mata a metalelor pretioase din pirita, caracterizat prin aceea ca în scopul recuperarii tuturor elementelor utile cu randamente ridicate si a optimizarii fluxului tehnologic se introduce zgura în amestec cu praf de cocs si eventual cu pirita cu arc, preîncalzit la 1300....1350 degree C, dupa care sarja se supraîncalzeste si se prelucreaza în conditii cunoscute.Process for the recovery of the useful elements from the slags resulting from pyrometalurgy of copper by melting in mixture with 2 ... 6% coke dust and possibly 5 ... 15% golden pyrite in the electric arc furnace at 1400. .1500 ° C, maintaining the melt for 30 minutes at 145 ° C for the volatilization of Zn and Pb, followed by further maintaining for 25 minutes in the temperature range mentioned for the copper casting and the possible transition of the precious metals of the pyrite, characterized in that, in order to recover all useful elements with high yields and to optimize the technological flow, the slag is introduced into the mixture with coke dust and possibly with pyrite with an arc preheated to 1300 ... 1350 degrees C, the batch is overheated and processed under known conditions.
