Objective of this study is to investigate the synergistic effect of dodecylamine kerosene as a collector in the reverse cationic flotation of iron ore slime.

Reverse flotation is a process that the gangue minerals report to froth products while the valuable minerals stay in the flotation cell as tailing. According to the types of the collector, it can be generally divided into anionic collector reverse flotation and cationic collector reverse flotation.

An effective collector plays a vital role in the reverse flotation of phosphate ore as well as sustainable production of phosphate fertilizer. Phospha…

The flotation activity of cationic gemini surfactant 1,4-bis (dodecyl-N,N-dimethylammoniumbromide) butane synthesized in our laboratory was compared with conventional monomeric cationic collectors dodecylamine and dimethyldodecylamine in reverse froth flotation of magnesite ore.

Two-stage reverse flotation process for removal of carbonates and silicates from phosphate ore using anionic and cationic collectors

Applying a two-stage reverse flotation process for removal of carbonates and silicates from phosphate ore using anionic and cationic collectors, this work aims at illus-trating the effect of ...

The practice of silica reverse flotation by amine derivatives has increased dramatically as more complex ores have to be mined and higher-grade iron ore concentrates with fewer impurities are requested by the steel industry. ICS amine based collectors are used for both for magnetite and hematite systems.

This work is based on a hypothesis that a further development in reverse cationic flotation of iron ores implies, a more detailed consideration of the nature of the Fe-bearing gangue minerals.

In reverse flotation, siliceous gangue materials are floated at approximately neutral pH using a cationic amine collector. In this method, carbonate minerals are floated by anionic collectors at acidic pH while depressing phosphate minerals with suitable depressants ( Sis and Chander, 2003, Tanaka et al., 1988 ).

Reverse flotation desilication is an indispensable step for obtaining high-grade fluorapatite. In this work, dodecyltrimethylammonium bromide (DTAB) is recommended as an efficient collector for the reverse flotation separation of quartz from fluorapatite. Its collectivity for quartz and selectivity for fluorapatite were also …

Commercial fatty acid (FA) and phosphate ester collectors were investigated in a reverse flotation process, assessing the impact of flotation pH, collector dosage, and type on the selectivity and recovery of calcite and dolomite.

The flotation performance was evaluated using a laboratory mechanical flotation cell at different process parameters such as pH, collector dosage, and Ca (OH) 2 dosage.

Reverse cationic flotation of quartz provided an effective way to remove quartz from iron ores, and with the development of cationic collectors, the shortages of primary fatty amines such as poor selectivity, low flotation speed and excessive has been improved (Yu et al., 2008; Filippov et al., 2014).
