| Copper-bearing colloidal pyrite ore is a refractory ore.The metallurgical performances of copper flotation are very low.In this paper,the research on process mineralogy has been done for investigating the relationship of the structure of this ore with flotation.This kind of ore has high contents of colloidal cbalcopyrite and pyrite,resulting in lower ore hardness easy overgrinding,easy oxidation and lower flotability of copper minerals,etc.This is the main reason for poor metallurgical performances of copper flotation at Dongxiang Copper Mine.In this paper,the metallurgical performances of copper flotation for the colloidal ore have been predicted. |
