Abstract
New technology research on comprehensive utilization of neutralized slag with high Cu, Bi and Te was earried out by using secondary acid pickling for copper removal, sodium sulfite for tellurium reduction and neutralization for bismuth sedimentation, which brings the completely industrialized recovery technology coming into being.The recovery of tellurium,copper and bismuth can be up to 92.8％ ,95.5％ and 97.2％ respectively.This new technology can be easily operated and brings remarkable economic benefits with simple equipments.关键词
