Study on Recovery of Valuable Metals from Wolframite Alkali-leaching Residue by Reduction Smelting AITranslate
Abstract AITranslate
The reduction smelting process was used to process wolframite alkali-leaching residue and recover valuable elements such as Fe,Mn,W,Sn and Nb in the form of alloys,and the harmful elements such as As and Pb were separated.The effects of reducing agent(graphite powder)dosage,smelting temperature and time on smelting efficiency were studied.The experimental results show that the alloying rates of Fe,Mn,W,Sn and Nb in wolframite alkali-leaching residue are 88.67%,56.28%,98.23%,67.74% and 84.72%,respectively,when reducing agent dosage is 16%,smelting temperature is 1550℃,and smelting time is 120 min.Meanwhile,As,Pb and Bi basically enter the smoke and dust.
