Investigation of the reverse flotation of iron ore in three …
1. Introduction. Flotation is a selective process for separating minerals from each other based on particle hydrophobicity. The flotation separation efficiency depends on the recoveries of the mineral species by both true flotation and entrainment (Cilek, 2009, Neethling and Cilliers, 2009, Wang et al., 2015).Both chemical variables and …

Reagents types in flotation of iron oxide minerals: A review
In this paper, several studies describing the processing of iron ores via direct and reverse cationic and anionic flotation are reviewed. The objective of this review was to present and identify the effects of different flotation conditions on removal of specific impurities in iron ore such as quartz, alumina, phosphorous, and sulfur.
