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 …

For the red ore that is beneficiated by the flotation process, the use of a high-efficiency thickener can obtain a higher underflow concentration and increase the dehydration rate of the concentrate. 2. Dehydration of iron ore concentrate. The use of inclined plate type high-efficiency thickener has a better dewatering effect.

1. Introduction. The flotation processes performed in the main iron ore beneficiation plants located in the Iron Quadrangle region (Brazil) consist of flotation of natural fine particles (below 0.15 mm, without grinding) or flotation of all the material after grinding using ball mills (run of mine).

The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to …

Again, the addition of polymer aids in the separation and thickening process. The disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry cake, which is sent for pelletizing. This process allows ore of very low magnetite content to be processed into a high quality product. Tailings
