— Desliming is the process in which ultrafine particles are moved from ore by sieving, ore washing, and grading. In beneficiation, the removed microfine particles are called slime, which is an interference factor during beneficiation and directly affects separation efficiency and beneficiation reagent consumption.
— Product from the secondary ball mills is classified by cyclones and cyclone underflow is returned to ball mill feed and cyclone overflow reports to final product which has 80% passing 105 microns. After two stage of deslime cyclones, ore is sent for the reverse flotation to produce final product >65% iron for pallet production.
— By using a large 500-mm (20-inch) diameter cyclone as the primary stage and a 250-mm (10-inch) or 150-mm (6-inch) cyclone as the secondary cyclone, many of the inherent errors of cyclones are taken to advantage. Some coarser low ash coal particles report to the overflow of the larger cyclone which is attempting to make a nominal 150 …
— Beneficiation methods of lithium minerals from hard rock ores were reviewed. ... The cyclone overflow is re-cycloned to remove the −15 μm slimes. The slimes account for 7.4% wt at 1.43% Li 2 O. The +15 μm material is conditioned at 55% solids in neutral pH conditions with 700 g/t of tall oil fatty acid and glycol-type frother.
Fine coal beneficiation via spirals is the most common process route in South Africa with desliming cyclones being used to deslime the fine coal before the spiral process. One would therefore assume that the performance of the desliming cyclones would be similar for these spiral operations but field data, as seen in Figure 1, indicates otherwise.
7 Unfortunately, cyclones do not provide for the most effective de-sliming of the feed to fine coal beneficiation plants, mainly as a result of the so-called 'short circuiting' of
