The desliming efficiency is affected by the dispersibility of the kerosene; thus, it is necessary to study the emulsion properties. A preliminary study was carried out to test the stability of the kerosene/aqueous emulsion by visually measuring the volume of sample phase separation at 25 ± 0.1 °C. Both water and a KCl saturated solution were ...

We recommend a maximum feed pressure of 125kPa for fine feed, and a maximum of 100kPa for coarse feed, to prevent excessive wear. But for fine particles or dilute feeds, the maximum pressure can be as high as 300kPa for the smaller cyclones – 400mmØ and less. Recommended maximum feed pressures are –. Cyclone Diameter.

capacity of the desliming screens is increased due to the larger screen apertures and in effect, the throughput capacity of the dense-medium section is increased. The 3 x 0.5 mm size fraction, which was previously processed in the dense-medium cyclones, is now added to the fine coal size fraction and processed by water-only methods

The desliming stage is considered critical, as a virtually slime-free product is necessary to minimize reagent costs and to ensure good potash recovery. Desliming is accomplished in two or three stages. The primary separation may be done with cyclones, syphon sizers or wet screens, while the secondary separation is usually accomplished …

Thickening is used during two primary mineral processing operations: water removal and desliming. During water removal, the pulp density is increased through the injection of flocculants. These flocs settle and create a dense pulp while clarified water is removed through the overflow. During desliming, fine particles are removed through the …

Desliming induced some changes in the physical, chemical, mineralogical and rheological properties of the tailings. CPB mixture of the deslimed tailings achieved the required consistency at a lower water to cement ratio. The short-term UCSs of CPB samples of the deslimed tailings were found to be 30– higher than those samples of …

With no desliming, the grade was 32.6 percent Cr2O3 and the recovery was 23.0 percent. This poor flotation response was attributed to adsorption of collector on the slimes and the formation of a slime coating on the chromite particles. Loss of chromite values to the slime fractions ranged from 1.5 to 8.4 percent as the desliming size …

The reference tailings are high in sulphide (34.7–37.4% S). Desliming appeared to lead to an increase in the sulphide content of the tailings (i.e. 39.2–42.2% S) presumably due to the removal of silicate minerals with the slime fraction as suggested by the decrease in SiO 2 +Al 2 O 3 contents of the tailings after desliming (Table 1). 2.1.4.
