Phosphate Floatation In Iron Ore. Anionic flotation of high-iron phosphate ores—Control of. Jul 01, 2009 The fatty acid flotation of a difficult-to-float igneous phosphate ore (26.2% P 2 O 5, 15.4% Fe 2 O 3) was investigated through batch flotation tests in the presence of soda ash.The poor flotation of this otherwise high quality ore was attributed to very high concentrations of …
Bench-scale flotation tests showed that 50% of Atrac can be replaced with non-ionic collector without impairing the flotation results. Results also illustrate that the non-ionic adsorbs on apatite in ... more difficult to pelletize iron ore fines that have been ren-dered hydrophobic in order to aid their recovery by flotation.

The influence of pulp temperature on the kinetics of apatite flotation from magnetite fines was studied using Atrac (fatty acid type) as collector and sodium silicate as dispersant at pH 8.5–9.0.
Iron concentration tailings contain many valuable minerals, including apatite, which is not currently being recovered despite its use to make fertilizers and chemicals. This article proposes a flotation circuit to recover apatite from tailings generated by mining in Chile, based on laboratory tests and using the "Split Factor" method. The iron tailings were characterized by …
The impact of the zeta potential and surface chemistry on flotation and deslime is also discussed. The aim of this paper is to provide a well-detailed, well-referenced source for the current status of iron ore flotation, …
It covers different types of collecting agents used in reverse iron ore flotation, the surface characteristics of minerals commonly present in iron ores (e.g., iron oxides, quartz, alumina-bearing ...

production, the iron ore is upgraded in a number of steps including, among others, flotation. The induced hydrophobicity of the iron ore concentrate caused by adsorption of the flotation collector may affect the pellet strength both in wet and dry state. In order to minimize the influence of the collector on pellet properties it is important to

In situ desorption experiments revealed that a large fraction of the Atrac was weakly attached to the hematite surface, as it was partially removed by flushing with water at pH 8.5 and 10. These results suggest that a separate washing unit after the flotation step could be beneficial in reducing the contamination of iron ore by flotation chemicals.

This belt of iron deposits stretches approximately 600 km along the Coastal Range, between the regions of Atacama and Coquimbo [7]. In this line, the tailings produced by the treatment of iron ores from the Cretaceous Iron Belt in the Mountain Range of northern Chile [8] are found, which contain iron oxide–apatite (IOA) deposits.
tailings can reduce waste materials and add more economic value to raw ore. Refs. [21,22] studied the flotation of apatite from iron tailings from IOA-type deposits. The processing of these tailings is a great challenge since the characteristics of the feed material can limit
