铜渣贫化及其高值化利用
Dilution Process of Copper Slag and Its High-Value Utilization
摘要
Abstract
Copper slag has gradually become a significant issue due to the growth of the economy and the constant increase in copper production.The accumulation of copper slag hinders the green and sustainable development of the copper industry.Valuable metals such as iron,copper,lead,zinc,gold,silver are present in copper slag,and their significant recycling value makes it an important sec-ondary resource.In this paper,we explore the physical,hydrometallurgical,and pyrometallurgical methods for extracting these precious metals from copper slag.This work also introduces an innovative technology for high-value copper slag utilization by the special metal-lurgical innovation team at Northeastern University.This technology enables the recovery of copper,iron,lead,and zinc from copper slag,and the preparation of cement clinker from tailings,thus achieving a high-value,slag-free,comprehensive utilization of copper slag.The paper provides a comprehensive review of copper slag utilization and offers some insights and recommendations for its large-scale,environmentally-friendly,and slag-free use in the future.关键词
