Description
Technical Field
The invention relates to a full-size-fraction deep vulcanization-coarse-fine-size grading enhanced flotation method for a muddy copper oxide ore, and belongs to the technical field of mineral processing.
Background
With the annual increase of copper demand, the reserves of high-grade copper sulfide ores which are easy to sort are greatly reduced, and copper oxide ore resources gradually become an important raw material for copper metal production, but copper oxide ores have the characteristics of high binding rate, fine embedding granularity, serious mud, complex mineral types and the like, so that the recovery difficulty is higher, and the comprehensive utilization rate of resources is lower. Copper oxide ores are generally concentrated by flotation, wherein the method is divided into a direct flotation method and a sulfide flotation method, however, when the direct flotation method is adopted, the selective separation effect of copper oxide minerals and gangue minerals is poor, and the method is not suitable for copper oxide ores with complex mineral composition. The sulfide flotation method is to add a vulcanizing agent to carry out pre-modification on the surface of minerals before adding a collecting agent, generate copper sulfide components with higher reactivity or even copper sulfide films on the surface of hydrophilic copper oxide ores through a vulcanization reaction, and then recycle the copper sulfide components by adopting a flotation process similar to the separation of copper sulfide ores.
Aiming at the problems that the traditional vulcanization flotation method is poor in vulcanization effect, a collector is difficult to stably adsorb, flotation indexes are not ideal and the like, the copper ammonia complex step activation copper oxide ore reinforced vulcanization flotation recovery method is adopted, gangue minerals in the copper oxide ore are inhibited by adding a combination inhibitor, then a novel activator copper ammonia complex is added for primary activation, a combination vulcanizing agent is added for surface reinforced vulcanization after the activation, the copper ammonia complex is added into ore pulp for secondary activation after reinforced vulcanization, and finally the copper minerals in the ore are recovered by sequentially adding the combination collector and a foaming agent for flotation, so that the flotation effect of the copper oxide minerals in the ore is improved, but the method is difficult to ensure the efficient recovery of the complex copper oxide ore with high mud content.
Copper mineral embedded granularity in the argillaceous copper oxide ore is finer, the flotation requirement can be met through fine grinding treatment, but the hardness of different minerals in the ore is greatly different, the fine grinding can lead to uneven granularity distribution of ground ore products, and a large amount of secondary mineral mud is generated, so that the flotation recovery of the copper oxide ore is interfered, the flotation efficiency and the quality of flotation concentrate are reduced, and the consumption of flotation agents is increased. The primary sludge and the secondary sludge have gangue minerals and copper oxide minerals, so that the copper-containing sludge cannot be directly thrown away.
Therefore, development of new flotation technology and technology is needed to realize deep vulcanization and efficient recovery of copper oxide minerals with different particle sizes in the argillaceous copper oxide ore, and improve the recovery utilization rate of complex and difficult-to-treat copper ore resources.
