Multi-metal ore, if the first suppressing floating a mineral beneficiation remaining mineral, activated and then float another mineral beneficiation, which in turn processes the recovery of useful minerals beneficiation floating containing two or more useful components It is called the priority flotation process. For example, the principle of floating beneficiation process priority copper zinc ore shown in Figure 6-23, which process is based on the quality of mineral flotation, and then sequentially to float float copper zinc. If in the above case, two or more kinds of useful minerals in the ore are first floated together to obtain a mixed concentrate, and then the mixed concentrate is sorted to obtain a qualified concentrate of different useful minerals. The process of mixing and recycling a variety of useful minerals is called a hybrid flotation process, also known as a full-floating beneficiation process. For example, the principle of mixed flotation of copper-zinc ore is shown in Figure 6-24. This process is to first float all the copper and zinc to obtain mixed concentrate and waste tailings, and then re-grind or remove the mixed concentrate. The copper is then preferentially floated to obtain a copper concentrate. In general, the mixed flotation ore is suitable for treating ore with poor ore and simple nature. In this case, the priority flotation and beneficiation has the following advantages: it can save grinding cost, save floating mineral processing agent, and save floating mineral processing equipment. When recovering more than three useful minerals, a partial mixing flotation process can also be applied, as shown in Figure 6-25. The difference between it and the full flotation process is that a part of the useful mineral to be floated first floats out. The floatable process is also called the mixed flotation process, as shown in Figure 6-25. It divides the useful minerals to be floated into two parts: easy to float and difficult to float according to the floatability. Flotation of the ore separately and then separation. It adapts to the same kind of minerals including complex polymetallic ore which is easy to float and difficult to float. Its advantages are that it can reduce the consumption of chemicals, eliminate the influence of excess chemicals on separation and flotation, and improve the flotation dressing index. The main disadvantage is the use of equipment more than full flotation. Our paper boxes are more than thick, we are a powerful factory with millions of stocks. Selected logistics, fast delivery.
