Dry desliming tests using a rotating wheel air classifier and factorial design were performed on a difficult-to-treat low-grade high-goethite Australian iron ore tailings. The results were compared with theoretically ideal size separation and a hydrocyclone desliming study using the same tailings. The air classifier performance was poorer than ...

The advantages of hydrocyclone desliming. Optional equipment for desliming operations includes hydrocyclones, classifiers, thickeners, etc. After continuous practice in recent years, the use of cyclones for desliming is the most feasible and reasonable. Compared with other desliming equipment, hydrocyclone desliming has …

For test A1, desliming of the 'as-received' sample at a cut point of 10 µm resulted in a significant loss (27 %) of fine chromite to the cyclone overflow. The sample was then subjected to flotation, sulphuric acid being added to reduce the pH to 2.5, with a rougher concentrate being cleaned in three stages in open circuit.

The role of desliming prior to flotation is important to achieve targeted gold grade and recovery. Abstract A laboratory-scale investigation was conducted to study the effects of flotation reagents and clay minerals on the recovery of electrum from the ore treated at the Dundee Precious Metals Krumovgrad operation.

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.
