Research on the Comprehensive Recovery and Utilization of Copper Tailings from a Copper Smelting Slag in Yunnan Province
摘要
Abstract
The copper tailings from a copper smelting slag in Yunnan contain 43.01％iron and 3.57％zinc.Approximately 65％of the iron exists in the form of magnetite,while zinc is primarily hosted in refractory zinc-iron spinel.An iron recovery technology process of"first-stage low-intensity magnetic separation-staged grinding-regrinding and cleaning"is proposed.Under the separation conditions of a grinding fineness of 70％passing-0.074 mm in the first grinding stage,a magnetic field strength of 0.1 T,and regrinding the rough concentrate to 85％passing-0.038 mm,technical indicators of an iron concentrate grade of 57.36％and recovery rate of 56.00％are achieved.The iron separation tailings can be used as cement raw materials.It provide technical support for the engineering application of the"copper recovery-iron extraction-building materials utilization"technology for copper smelting slag.关键词
