Application of Reverse Flotation in Upgrading Western ...

Aug 01, 2019· The addition of magnetite has likely two effects on the reverse flotation of iron ore. It acts as a depressant by hindering transfer of fine hematite into the froth. It also acts as a flocculant to aggregate fine hematite particles, and aggregates formulated do not coat easy the quartz surface through a sliming process ( Ma et al., 2011, Lima et al., 2016 ).

APPLICATION OF REVERSE FLOTATION METHOD FOR THE …

Jan 01, 2010· The paper describes effective reagent combinations for removal of silicates by reverse cationic flotation from magnetic concentrate in magnetite ores processing. 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.

(PDF) Effect of reverse flotation on magnetic separation ...

Upgrading of a Koolanooka magnetite iron ore sample provided by Kingstream Steel Ltd was investigated using low intensity magnetic separation (LIMS) and reverse flotation. The ore contained 38.6 per cent iron, 37.8 per cent silica, 6.5 per cent magnesia and 0.54 per cent alumina, with the main minerals in the ore being amphibole (42 per...

Reverse Flotation of Quartz From Magnetite Ore with ...

2. 2. 2. Flotation Experiments Reverse cationic flotation batch tests were conducted using 1kg of fluorspar tailings in 2.5l Denver D12 flotation cell at pulp density of 40% solids, impeller speed of 1000rpm and air flowrate of 60%. Before flotation, the pulp was first conditioned with starch for 4min and then conditioned with collector for 4min.

Optimising Western Australia Magnetite Circuit Design

A combined cationic (amine) and anionic collector (sodium xanthate) was also reported to be effective for the flotation of zinc oxide at pH 11 [14]. In this study, attempts were made to enhance the selective separation of pyrrhotite from magnetite. Flotation experiments were conducted with different collector suits (xanthate, dixanthogen, and ...

of potash, we can deliver either standard amine produced from different types of fatty acids, or special formulations. In some cases, where clay minerals are present in the ore, a slime flotation step using flotation collectors is undertaken prior to potash flotation. We also offer collectors for reverse flotation …

reduction process in rotary kiln for 3 hours at 900 °C by transforming limonite/goethite to magnetite containing Fe 45.6 % and Ni 1.16 %. The reverse flotation tests were focused on the separation of iron mineral from nickel mineral using amine complex, ARMAC-C, a commercially available amine thioacetate as collector.

A Simple Introduction on the Magnetite Reverse Flotation ...

Reverse flotation studies on magnetite samples have revealed that the use of starch as a depressant of Fe-oxides has a hydrophilic effect on the surface of Fe-bearing silicates and significantly ...

Flotation in a magnetic field and preparation of magnetite ...

Reverse anionic flotation of magnetite is conducted at a higher pH value (pH 11–12) than reverse cationic flotation (pH 10–10.5). Since the point of zero charge (PZC) of pure magnetite is around pH 6.5, the surface charge of magnetite in reverse cationic flotation (pH 10–10.5) would be less negatively charged than that at pH 11-12 (Li et ...

(PDF) Effect of reverse flotation on magnetic separation ...

fatty amines such as dodecylamine were used in reverse cationic flotation. The fatty amines were of low solubility in pulp and were replaced by more soluble ether amines later. Papini et al.[15] compared the efficiency of various cationic collectors including fatty monoamine, fatty diamine, ether
