According to foreign intelligence technology forecasting, weakly magnetic iron ore large-scale development, processing and utilization, it will be one of the major breakthrough in the 1980s to the end of the century in this industrial technology projects. In fact, the United States, the Soviet Union, Germany, Canada, Australia and other countries have stepped up their research on low-grade weak magnetic iron ore beneficiation since the 1950s. In the 1960s, there was a major refinement and flotation of hematite. progress, or put into operation during which the technological transformation of the representative processing plant are: Canada's Carol; US Pili Qi, Groveland, Republic (heating flotation); tin Hing South Africa and Liberia Bunge et al. In the 1970s, with the continuous rise of the world steel industry, the scale of iron ore dressing and ore dressing equipment was moving toward large-scale development. During this period, two remarkable mineral processing technologies were: selective flocculation-de-sludge-cation back-floating The application process and wet magnetic separator are used in the treatment of fine-grained low-grade weak magnetic iron ore. Its representative plants are Tilden in the United States, Septe Ellis in Canada, Lisakov in the Soviet Union, Samarkcu in Brazil, and Coy.
Since the 1970s, a large number of fruitful experimental research work has been carried out on the anti-flotation process of the Anshan-type lean hematite in China. Many processes have been tested by industrial-scale pilot plants.
(II) Application of weak magnetic iron ore reverse flotation process
When the type of iron minerals selected for ore is complex and variable, and the gangue mineral is a single quartz , it is obviously advantageous to use the reverse flotation process. However, for fine-grained iron ore (such as hematite treated by the Tierden plant in the United States, the inlaid grain size is 20-40 μm, and it needs to be ground to -25 μm 85% to achieve monomer separation), due to fine grinding. The large amount of slime produced has a great impact on reverse flotation. If the mud off pre-election mud off using conventional methods, will result in the loss of large amounts of metal, for research flocculation Fromer and other US Bureau of Mines Twin Cities Research Center, people - desliming - reverse flotation process. That is, the starch is selectively flocculated, and the difference in sedimentation speed between the iron mineral floc and the dispersed, unflocculated quartz and the low-grade slime is increased, and then a large amount of low-grade slime is removed by hydraulic dewatering to purify the slurry. It creates extremely favorable conditions for the reverse flotation operation in the next stage, thus improving the sorting effect.
China's Baotou Steel Concentrator and Hunan Jidong Iron Ore Concentrator have conducted selective process research on selective flocculation and desliming. In recent years, the use of strong magnetic desliming as a preparatory work for reverse flotation has been generally emphasized, and various combined processes such as weak magnetic-strong magnetic-reverse flotation or re-elasticity-weakening-strong magnetic-reverse flotation are formed. The advantages of using strong magnetism as a preparation for reverse flotation are mainly due to the fact that the strong magnetic separator can throw a large number of low-grade tailings and slime; the enrichment ratio is large, so that the amount of selected ore in the reverse flotation is greatly reduced, and the water for tailings treatment is reduced. Recycling and recycling bring convenience, and the discharge of mineral processing water is easy to treat. The disadvantage is that the capital investment is large. Whether it is flocculation or demagnetization or strong magnetic desilting, it is necessary to enter a strict technical and economic comparison.
For the Anshan-type lean hematite ore in Daqishan, the combined process of re-election and weak magnetic pre-stage grinding and pre-separation can also be used to separate the coarse-grained high-grade concentrate in advance, and then demineralize by strong magnetic separation. The ferromagnetic minerals and the strong magnetic concentrates enter the reverse flotation operation. In this way, a combined process of stage grinding, magnetic, heavy and reverse flotation is formed, and different beneficiation methods are mutually extended and complement each other to ensure product quality and metal recovery rate of the entire sorting operation.
In short, the cationic reverse flotation process using amines as collectors and corn starch as inhibitors, in the various joint processes for processing weak magnetic iron ore, will follow the development of China's agriculture, chemical and other related fields. Gradually expand the scale and scope of its application.
