The company carried out a test campaign with its own Hybrid Flotation cell in the laboratory. An iron ore concentrate containing 67 % Fe and 1.3 % S was used as the feed material. The target of the test campaign was to reduce the sulfur content to below 0.4 % in the final concentrate. The required iron recovery was at least 95 %.
First, the collector is added to the iron ore slurry to selectively coat the iron oxide particles, making the surface hydrophobic. The slurry then goes to a flotation cell, where air bubbles are generated using an impeller and aerator Figure 1.2.4 .
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

The first plant using this kind of flotation technology was in 1993/94 as a means to provide a fast separation of sulphide and to re-use existing mechanical cell circuits to float oxide copper. In this way only two rougher cells were required, and together with one cleaner stage, were sufficient to float sulphide to sale quality Sánchez, 1997 .
At the Huasco Pellet Plant of Compañía de Aceros del Pacífico, Chile, the production of iron concentrate suitable for pellet feed from a low-grade iron ore was technically evaluated. In this study, three treating schemes including comminution, magnetic concentration and flotation in pneumatic cells were tested. The best results were obtained at the laboratory scale

The mechanical flotation cell is a 3 L modified Leeds batch cell which can be operated at impeller speeds of up to 1500 rpm and air flow rates of up to 7 l/min. The froth depth is adjusted and maintained by level control. The oscillating grid flotation cell OGC is a 10 L cell which is agitated by 19 grids mounted on a vertical shaft.
The flotation cells are designed for a variety of throughput requirements, ranging from small pilot sized cells with a diameter of 0.8m, processing 6 – 10 m 3 /h of feed; to cells with a diameter of 6.5m, handling feeds of 1500 m 3 /h. The flow rate is dependent on the feed pressure and rate of concentrate removal.
The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells see Figure 1 , and it does not require air compressors to aerate the suspension of ground ore particles and water known as a slurry or pulp in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
The Eriez Flotation provides advanced engineering, metallurgical testing and innovative flotation technology for the mining and minerals processing industries.

First, the collector is added to the iron ore slurry to selectively coat the iron oxide particles, making the surface hydrophobic. The slurry then goes to a flotation cell, where air bubbles are generated using an impeller and aerator Figure 1.2.4 . At this step, the frother for example, fuel oil is added to the ore slurry to form stable
The main demand for large flotation units today is from iron ore and copper. Generally only copper will go up to 600 m 3.” New Mechanism From Metso. Metso’s flagship product for flotation, the RCS flotation cell, is an all-purpose flotation machine suitable for appli ions including roughing, cleaning and scavenging.

Imhoflot pneumatic flotation technology has evolved through 25 years of industrial appli ions. This has led to the development of the patented Imhoflot G-Cell where centrifugal forces are used in the cell to quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required.

The main iron ore processing plants in Brazil operate through reverse ionic flotation. Many studies have been conducted in order to improve flotation efficiency by optimization process variables. The pneumatic flotation cell stands out due to the simplicity to and to the intense contact particle/bubble promoted by the pulp feeding system.
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important appli ion is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
contain copper, lead, zinc, iron, m.olybdenum, co balt, nickel, and arsenic. The process, con1n1only called si<in flotation, stipulated that dry ore be sprin kled, without agitation, onto the stnface of a body of water. The heavier materials sank to the bottom, while the surface tension caused the lighter metals
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
