Collective flotation flow sheet. Which is also called mixed flotation process. It first emerges all useful ore together, and then separates them gradually. This is a common polymetallic sulphide ore flotation process and applicable to the raw ore of low grade, mineral density symbiosis, and similar floatability. Under whose effect, useful minerals are disseminated collectively, and we can get mixed concentrate and waste tailings by rough grinding. Compared with Selective flotation flow sheet, the process has the advantages of saving floating grinding equipment, reducing power consumption, saving medicine and infrastructure investment. But they are not prominent in treating rich ore. Disadvantages are the subsequent separation difficulty if given excessive catching agent in flotation, poor selection index if nature of the ore is complex and changeful.
Partial mix-flotation. It first floats certain kinds of useful minerals, restrain other minerals, then activate and float restraint minerals. The earlier mixed concentrate has to be floated again, and then we get the qualified concentrate. However, we it shouldn’t be adopted when the floatability are not similar.
Isoflotabity flowsheet. When a same mineral contain different floatability parts, we can use such process. Selection is according to floatability. In the flotation of main mineral, we can float the other parts of identical floatability first, and form mixed concentrate, then separate. This process can avoid problems like separation difficulty caused by strong inhibition and strong activation. Compared with selective flotation flow sheet, it reduces the dosage of the medicament, removes influence by excess drug and is beneficial to improving selection index.
The most popular of Henan crusher in the domestic market is still the jaw crusher, impact crusher, cone crusher and other products. But in the international market the highly automated crusher is the main direction in the future development. Therefore, Henan Hongxing Heavy Industry Machinery explore to the domestic market by using advanced Europe type jaw crusher, Europe type impact crusher and hydraulic cone crusher. Meanwhile, we actively research the new type and high-end equipment, open the international market by the automatic and high technology mobile crushing station. In a word, the research and development of high technical and high-end crusher is the most realistic measure for improving the crusher industry.
