The sulfide ore flotation process can be studied by both chemical and electrochemical phenomena considering the interfacial energies. A broad application of this process in industrial field is the flotation of iron ores which is of two types: direct and reverse flotation. The later one
Special Issue Information. Dear Colleagues, Iron ore flotation is a key technique to concentrate intermediatelowgrade ore, in order to reach the market requirements for highergrade concentrates of iron. The presence of some impurities in addition to quartz in iron ore, aluminium silicates, and minerals containing phosphorus
The increased use of iron ore flotation has resulted in the reduction of gangue impurities . Flotation has thus produced iron “superconcentrates” with limited contents of silica, aluminium oxide and other impurities prior to subsequent metallurgical processes [8, 9]. Based on the collector used, ironbearing metallic mineral flotation
Building on more than 80 years of experience in designing mineral processing chemicals for mining applications, we closely collaborate with our customers to customize solutions that fit each individual ore. Our product portfolio includes flotation collectors, frothers, and depressants such as NaSH and carboxymethyl cellulose (CMC); dewatering
Fatty acids are widely used as a collector in the reverse anionic flotation of iron ores. The most popular anionic collectors used in iron ore flotation practice are oleic acid and its soaps [16,26]. The oleate in aqueous solution forms different species and which species dominate is dependent on pH.
Flotation response of iron ore depends on its impurities. •. Silica rich ores float better compared to alumina rich ores. •. Clay and gibbsite coat on hematite and hinder flotation. •. SEM studies support less coating of quartz due to coarser size. •. Silica in the form of jasper present in BHJ ore is less floatable.
Two grades of iron ore came out of this venture: i) The beneficiated NIOMCO ore with Fe total of 65.74%. ii) The rebeneficiated NIOMCO ore with Fe total of 67.40%. These formed part of the initial efforts and success in the production of steel from the locally available iron ore at Itakpe in the middle belt region of Nigeria. PELLETIZING OF
The significant applications of iron ore flotation are reviewed along with an abbreviated discussion on theory and reagent use. Problems or conditions which have militated against a widespread adoption of the flotation process by the iron ore industry, are discussed in contextual relationship to supply, economics, alternatives, and process
the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.
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 flotation, and anionic reverse flotation are reviewed. A

Iron ore flotation With the continuous consumption of highgrade iron ores, various methods have been proposed to deal 6 with iron ores in lower grade to meet the rapidly growing demand. In industry cases, the iron ores containing less than 2.0% SiO 2 will be required [42]. In practice, however, the enriched primary concentrates still contain a
Out of several reagents used in iron ore reverse flotation, depressants play a crucial role in selectively making the iron oxides hydrophilic and prohibiting them from reporting to the ganguerich froth phase. Starch is widely used as the depressant in iron ore flotation. The present paper attempts to highlight different facets of starch as an

Figures 3(a) and 3(b) showed that an increasing PAM or PDADMAC concentration reduced the iron flotation recovery. However there was very little reduction in iron grade. When the concentration increased from 0 mg/L to 3 mg/L for PAM and 0 mg/L to 30 mg/L for PDADMAC, the recoveries of iron decreased from 74.66% to 66.74% and
Currently, the reverse flotation of iron ore with cationic collectors is the most widely used flotation technique in the iron ore industry (Uwadiale, 1992, Scott and Smith, 1993, Peres and Correa, 1996, Vieira and Peres, 2007, Ma et al., 2011). This process floats out the main gangue mineral quartz from iron ore by using cationic collectors.
The granulochemical analysis of the flotation residue showed that 79.0% of iron and 86.0% of aluminum are contained in the fraction below 37 µm. In desliming of the sample in 37 µm, recovery was 75.2% silica and 61.4% mass reduction. In this step, the SiO 2 content increased from 33.4% to 67.0%.
