The development of selective collectors for cassiterite flotation is a relatively popular field . Oleic acid and its derivatives are the most widely used collectors in oxidized ore flotation [9,10,11,12]. The downside of this fatty acid collector is its low selectivity and poor solubility at low temperatures .

The fatty acid condensed with the alkanolamine can operably be a fatty acid having a saturated or unsaturated aliphatic group. The fatty acid can suitably bear hydroxyl substituents on its alkyl portion, but such substitution does not impart any substantial advantage.
The effect of lead ions on cassiterite flotation with salicylhydroxamic acid as collector was assessed by a combination of microflotation tests, adsorption experiments, zeta-potential determinations, and X-ray photoelectron spectroscopy (XPS) analysis in this work.
With regard to the pH value of the cassiterite flotation pulps, one will realize that the pH depends strongly on the collector system of choice. Oleic and other fatty acids require a 7.5 to 8.5 pH level in most cases. The phosphonic acids are used in GDR at a pH of 6.0.
such reagent that is used for cassiterite flotation. Hydroxamate RCO(NHOH) as a fatty acid derivative, salts of which are chelating type of chemical reagents and are extensively used in the flotation of minerals due to their strong and selective complexation with a number of metal ions [17−19]. The non-ionic hydroxamic acid
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
ﬁrst patented the use of hydroxamic acids or their salts as collec-tors for ore ﬂotation. Much research followed with the develop-ment of a number of different hydroxamate collectors. In the former USSR, a hydroxamic acid collector named as NM-50 was used as a collector for wolframite, cassiterite and rare metal ores (Gorlovskii et al., 1969).
However, the selectivity of fatty acids is too poor to separate the cassiterite from gangue minerals. From then on, various cassiterite flotation collectors with higher selectivity have been ...
Flotation is an indispensable way to recover the fine cassiterite particles which are lost in gravity separation tailings [1–4]. Fatty acids were reported in the 1930s as the earliest collectors used in cassiterite flotation [5–7]. However, the selectivity of fatty acids is too poor to separate the cassiterite from gangue minerals .
