Abstract

The invention discloses a beneficiation method for treating copper smelting slag to solve the problem of incapability of obtaining higher recovery rate under the condition of guaranteeing the concentrate grade in traditional flotation. The method adopts segmented flotation of copper ores contained in copper slag, that is, the quick flotation of part easy-floating copper ores is firstly performed; and then, the floatation is performed for difficult-floating copper ores. The copper smelting slag, namely raw ores are grinded to a certain fineness; the copper ores are collected through adding a copper smelting slag collection foaming agent; and the combined collection foaming agent is n-butyl xanthic acid, ammonium dibutyl dithiophosphate, lignocaine dithio formic acid cyanoethyl and terpenic oil. The beneficiation method is simple in process, and is easy to be managed and operated in scene; and the process can obtain higher economic and technical indexes. The used medicament is environment-friendly; and finally obtained copper concentrates are higher in grade and recovery rate.

Description

Technical field

[0001] The invention belongs to the technical field of copper smelting slag beneficiation, and specifically relates to a beneficiation method for processing copper smelting slag. Background technique

[0002] A large amount of solid waste will be generated in the process of non-ferrous metal smelting, and its comprehensive recovery has now become a new hot spot in the development and utilization of secondary resources. It has very important strategic and practical significance in both environmental protection and economic aspects.

[0003] At present, the beneficiation method for the recovery of copper smelting slag produced in the process of non-ferrous metal copper smelting mainly adopts conventional flotation technology to recover. This method has the following problems: (1) The copper mineral substance composition of copper smelting slag is complex and floatable The difference is large. Conventional flotation cannot obtain a high recovery rate while guaranteeing...
