Common methods of Copper ore processing At present, we always use flotation method, magnetic method, gravity separation method, pyrometallurgy and hydrometallurgy method to select copper ore.
Brief introduction of copper ore selectingGenerally, we adopt simple process in extracting copper ore, after grinding for a period of time, the mesh fineness-200 contain about 50% ~ 70%, 1 time of rough selecting , 2 or 3 times refine selecting, 1or 2 times Tailings Scavenging. If the particle size of the copper ore content is too relatively very small, we can consider to use stage grinding selecting process.
Bornite picture
When dealing with bornite, most factories adopt the stage grinding selecting process, namely they grind the rough concentrate ore at first and then finely select it.
After a period of coarse grinding, rougher flotation and tailings scavenging, then grind the rough concentrate again and select again to get high grade copper concentrate and sulphur concentrate. Coarse grinding fineness-200 mesh contains about 45% ~ 50%, second grinding fineness-200 mesh contains about 90% ~ 95%.
Dense copper ore always contain chalcopyrite and pyrite, pyrite is often activated by secondary copper content, pyrite content is always higher and it is difficult to restrain, thus makes selecting process difficult. In the selecting process, we get both copper concentrate and sulfur concentrate.
Usually, the tailings after copper selecting is sulfur concentrate. If the gangue minerals content exceeds 20% ~ 25%, we need secondary separating to get get sulfur concentrate. When dealing with dense copper ore, we often use two part grinding or stage grinding, grinding fineness requirement is more strictly. Reagent usage is much bigger also, xanthate is 100 g / (t undressed ore) above, lime 8 ~ 10 kg (t raw ore) above.
Make suitable production line according to local copper ore environmentAccording to the diversity of the copper ore, we can choose re-election against re-election, flotation reverse flotation method and many other kinds of processing methods. SX Heavy Industry Co.,Ltd can make the most suitable production line according to your local ore environment.
