When the material to be process by the flotation contains many kinds of components to be recovered, it needs to base on the floating property and the symbiotic relationship to determine the order of the different components to get the products separately. In the production, the flotation process is usually used preferentially in the lead and zinc ore. The following will introduce it simply.
In the practical production, by the different beneficiation order, the processes to be adopted can be divided into four categories that are preferential flotation process, mixed flotation process, partial flotation process and equal flotation process. Preferential flotation process means a process that every component to be recovered in the material will float one by one and then pre-recovery component rich in one will be got finally. Mixed flotation process refers to that all the components in the material will be floated together and the intermediate products having been got will separated by the flotation. Partial flotation process indicates a process that partial components in the material will be recovered firstly and the rest will be inhibited as well as other components to be recovered will be floated. While equal flotation process means a process that the components to be recovered with similar floatability will be floated together and then separated finally, which is suitable to process the material with components which are partially difficult to float and partially easy to float.
Among the beneficiation orders of the lead and zinc flotation methods, the preferential flotation process is adopted firstly. By the different floatability of the lead and zinc, the lead concentrate with good floatability will be floated firstly and then the zinc concentrate with poor floatability will be floated. Preferential flotation process is suitable for the ore with gangue dotted with less coarse particles. Before determining the mineral flotation order, the techniques of Xinhai ore dressing institute will make a analysis on the sample and put forward reasonable beneficiation process by the beneficiation report. The practice shows that the beneficiation process is advanced and practical which has won the trust of our customers.
