Canadian Review of Saskatchewan potash beneficiation process


Pumps, and sometimes simultaneous operation of these two pumps, each pump capacity of at least 75% of total capacity. 3.6 centrifuge and dried products generally conical sieve centrifuge with a flotation concentrate in the brine removal of foreign metal ore beneficiation 2003.10 26 (Figure 7). Downstream gas combustion rotary dryer and fluidized bed dryer used to dry concentrate potassium. For the rotary dryer,diesel store paris, not all, at least most of the direct thermal shift. In order to reduce the noise level, the dryer door ring removed. Feed opening screen in Figure 7 Figure cone Jazz effort to dryer exhaust into the vortex dust collector in general, followed by wet scrubbing. In a processing plant, the electrostatic deposition device to purify the final exhaust. In some cases, the effect of low-pressure wet scrubbing device is not very good, but it is combined with the high stack effect can be improved. 3.7 grading and compaction of the potash flotation has been the general standard or fine grain size class,Salvatore Ferragamo outlet, although it may contain some coarser particles. In order to obtain coarse-grain-level and granular products should be established compaction plant. Compaction plant scale production of coarse salt and directly related to the number of granular salt. After drying, the product screen by double-rotation (Figure 8) is divided into three grain-level products: 2.35 ~ 0.85mm (8 ~ 20 mesh) coarse-grained product ,1.18 - 0 .30 mm (14 ~ 48 mesh ) standard products, and 425 ~ 149m (35 ~ 100 mesh) fine products. As the operation of technical procedures and screening efficiency, product size to overlap. Screening over the products stored in silos, waiting for sales or further processing. Figure 8 Schematic diagram of the double-rotary screen by a good mix of dust off the heat (130 ℃) tablets to give to the compactor (Figure 9). Into two high-pressure roller will be pressed into the material thickness of 16mm film. With crusher broken pressed into the film, and then sieving into coarse granular product and the product. Compactor sizes from 6100mm × 610mm × 181t,mulberry outlet, 710mm × 710mm × 270t to 1000mm × 1200mm × 680t. Divided by the tonnage of the final product to the feeding amount of compaction plant to be constant conversion factor to the efficiency of compaction plant, plant operating efficiency is generally a good compaction of 30%. Figure 940x4oI chu dnm pressure to buy products and machine coarse granular product mix with a little water, then drying the so-called polishing loop. Its purpose is to fill the cracks in particles, and the elimination of grain edges and corners, and lower transport and handling issues that arise during the dust. Determined by packing the product sales strategy. Products and market trends require coarse granular products because they can be easily mixed with other types of fertilizer, to meet almost all the fertilizer requirements. In North America and Europe no longer apply the standard size products and fine products, in the South American market in very small quantities. Only in China and other Asian countries are still applying this small grain of potassium products, a certain percentage of mixing with other fertilizers. 3.8 crystal crystal is to get industrial grade potassium chloride (ie K2o content of 62.5% of the soluble grade of potassium chloride) in the process. This process is 110 ~ 110 ℃ hot water when mixing with potassium, so potassium selective dissolution, and rock salt to leave. Selected machine will be insoluble in sodium chloride and water insoluble removed. Selected to overflow into the crystal circuit, which consists of 4 to 5 cycles of vacuum machine (Fig. 10). Gravity or by pumping the liquid crystal transfer between segments, while the solid discharged from the loop. In the mold, the salt water cooling to below 20 ℃, selective crystallization to obtain high-purity KCl. Figure 10Swenson tube refrigerant into the evaporator cooling crystallizer (the transfer p. 47) 2003.10 47 foreign metal ore dressing (on the next page 26) can be used as secondary crystallization process, recycling crushing and fine potassium . This fine granularity of potassium for effective compaction are too thin, so need to use a standard size selected crystallization products of the product as a white product sales, or floating with the standard grain size concentrates or granular concentrate mix. In 2000, Saskatchewan potash mine a few crystals were obtained with the flotation plant 18,ed hardy uk,000 t of fine potassium chloride, accounting for 18% of their total output. 3.9 recovery of several plant Saskatchewan potash mine recovery shown in Table 3. Table 3 published in potassium recycling things 4 Conclusion Saskatchewan potash mine in Canada has long been established, it is a mature province and the federal Industry. In recent years, quality has increasingly become a concern for manufacturers of Saskatchewan potash mine is an important factor. Emphasis on making the coarse product key treatment processes (such as coarse-grained flotation,GHD Glätteisen günstig, screening and compaction products) continuously improved.
