Studies on the influence of a flotation collector reagent

The properties of iron ore green pellets with varying additions of a surfaceactive flotation collector reagent (Atrac) were studied by smallscale balling The Lead, zinc, and iron flotation kinetic rates in the lead flotation stage at pH values of 6 and 8 were shown in Fig 10 As it can be seen, there is a sharp increase in Critical importance of pH and collector type on the

Froth Flotation of Iron Ores

A variety of flotation routes have been developed to remove silica from iron minerals The flotation routes of iron ore can be classified into five major groups, ie this process in industrial field is the flotation of iron ores which is of two types: direct and reverse flotation The later one is again based on two different types as Froth flotation process and its application Wiley

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic His "Bradford washer," patented 1870, was used to concentrate iron, copper and leadzinc ores by specific gravity, but lost Our product portfolio includes flotation collectors, frothers, and depressants such as NaSH and carboxymethyl cellulose (CMC); dewatering and anticaking processing aids; Mining Nouryon

Studies on the influence of a flotation collector reagent on iron

Atrac 1563 is a yellow, fairly highviscosity liquid (150–200 mPa s at 20 °C) consisting of protonated carboxylic acids A 5% emulsion was prepared and the pH was adjusted to 85 ± 01 using NaOH Working solutions were prepared by further dilution of a freshly prepared 5% emulsion and used within 24 h of preparation 22Iron ore flotation started with direct flotation of iron oxides using selected anionic collectors such as petroleum sulphonates, fatty acids and hydroxamates They also experimented and showed that the adsorption of Atrac 1563, in the presence of calcium ions, resulted in an increased contact angle of the magnetite particles (despite theInvestigation of Adsorption Mechanism of Reagents

Flotation of Iron Ores: A Review Taylor & Francis

ABSTRACT A tremendous amount of research has been done on refining the flotation process for iron ore and designing the reagents which go into it This paper reviews the industrial practices and fundamental research surrounding iron ore flotation The advantages and disadvantages of direct flotation, cationic reverse For an apatitebearing magnetite ore, successful separation was achieved using a fatty acid mixture (Altrac 1563) of 9598% tall oil and 25% maleic anhydride as a collector, and sodium silicateStudies on the influence of a flotation collector reagent on iron

Interactive effect of minerals on complex ore

Froth flotation is the most effective industrial method used to separate finegrained minerals The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, Understanding of the interactions between iron oxides and flotation reagents is important both for flotation and agglomeration of iron ore Model systems comprising synthetic iron oxides Flotation collector Atrac 1563 has a complex chemical composition: 50100 % ethoxylated tall oil ester of maleic acid, and 15 % maleic anhydride (AkzoINTERFACIAL PROPERTIES OF NATURAL MAGNETITE
