Floatation Of Iron Ores

Effect of Slimes on Iron Ores Flotation

02-01-2012· The presence of slimes is, in general, harmful to the flotation of iron ores, affecting the selectivity and the quality of the concentrates, besides causing an increase in reagents consumption. This work describes the behavior of different iron ore types from the Iron Quadrangle, Brazil, with respect to desliming in hydrocyclones and flotation, including a study on the dispersion degree as a

Improving recovery of iron using column flotation

01.11.2020· According to Lima et al. (2005), the most common route used by far for flotation of Brazilian itabirite ores was cationic reverse flotation, where quartz is recovered from the froth and iron oxides remaining in the pulp phase. The typical feed to a flotation system in the iron ore industry consists of particles in the size range between 10 µm and 300 µm. The slimes fraction (<10 µm) are removed using hydrocyclones prior to flotation

Flotation of Iron Ores: A Review: Mineral

19.11.2019· A novel stepped flotation technique is discussed for the treatment of carbonate-rich iron ores. The necessity of desliming to enable effective flotation is discussed in detail. Selective flocculation desliming is discussed in particular detail as it is the primary deslime methodology used in industry. This paper also describes a large variety of reagents commonly used or in development in each

Flotation efficiency of different iron ore size

The flotation efficiencies of the individual size classes of iron ores are determined by the technological procedures employed. Under all the investigated conditions and for ores from different deposits maximum efficiency is observed for the −50+20 μ classes. 2. The use of petroleum products under direct flotation conditions greatly increases the beneficiation efficiency of the size classes

Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse flotation of iron ores

10.11.2019· However, in the anionic flotation of silica from iron ores, such as described here, the chief source of difficulty is believed to be from nonflotation of silica slimes. In discussing the nonflotation of slimes, Gaudin lists several causes for their recalcitrance, including (1) low probability of encounter with air bubbles, (2) chemical refractoriness of the surface of slime, which may be
