Where is the flotation plan selected?

Flotation useful components containing two or more multi-metal ore, if the first rest suppress flotation of a mineral mineral, activated and then another mineral flotation, which in turn processes the recovery of useful minerals called priority Flotation process. For example, the principle of flotation of copper zinc ores the process 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 flotation flotation process, also known as a full flotation 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, obtain mixed concentrate and waste tailings, re-grind or remove the mixed concentrate, and then Priority float copper to obtain copper concentrate. In general, mixed flotation is suitable for the treatment of ore with poor ore and simple nature. In this case, the preferred flotation has the following advantages: it can save grinding costs, save flotation reagents, and save flotation equipment .

When recovering more than three useful minerals, a partial blend flotation process can also be applied, as shown in Figure 6-25. It differs from the full flotation process in that a portion of the useful mineral to be floated is first mixed out.

The floatable process is also called the hybrid 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, then separate. It adapts to the same mineral, 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 the separation flotation, and help to improve the flotation index. The main disadvantage is the use of more equipment than full flotation.

What tests should I do?

1. Simple exploration of mineral processing test - before the purchase of mineral rights, meet the investment analysis and reduce the initial value assessment of investment risk.

2. Feasibility test of ore - It is used for detailed geological analysis and analysis, to meet the evaluation certificate, and to determine the reasonable process and reasonable process indicators.

3, system process test - practically used before the construction of the plant, meet the design finalization, find the law to determine the best process indicators.

4, technical research and research - the use of mine disaster technology is unsolved, to meet the improvement of efficiency, product failure to recover low cost and high time.

5, process flow verification test - the actual use of ore properties comparison, to meet the choice of pharmaceutical plants, the mine has different ores to determine the adaptability.

6, process flow test - practically used to produce the factory, to meet the current factory investigation, the selection of factory physical examination analysis and plant selection.

Which items should be tested?

1, determine the type of ore ---- need to do spectral analysis and rare element test.

2, to identify the specific nature of the ore - need to do multi-element analysis to determine the content of valuable and harmful elements.

3, to find out the relationship between minerals in the ore, content and composition - need to do rock and mineral identification, has a significant guiding significance for mineral processing.

4. Determine the specific existence form and distribution of elements in the ore. It is necessary to do phase analysis and have guiding significance for mineral processing.

5, concentrate, tailings test --- need to do valuable elements and harmful elements.

6, the original ore and concentrate water, the proportion of ore is determined - the actual measurement of mineral processing.
