· Although direct anionic flotation was the first flotation route employed in the iron ore industry, it was later largely replaced by the more efficient flotation route. The application of flotation in China in recent years and high metal loss in desliming.

Shandong 1500t/d Processing Project. Hongxing increased anionic reverse of magnetic concentrate on the basis of the single magnetic separation . concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener.

The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants. Flotation has now become the most widely used process for extracting many minerals from their ores. Schematic diagram of a flotation separation cell.

Froth is a for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Hongxing increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener. Finally, iron concentrate was increased from 64.25% to 67.22%.

· Iron ore beneficiation is a multi-stage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content. The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it.

1. - supply and demand outline 1.1 Types of ores can be classified in different ways. The most important has to do with the content. In many cases, with a total content of 60% to 63%, or greater, is regarded as high grade, and with a lower …

First, the collector is added to the iron ore 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 .

The process of flotation is mainly affected by the small mass of the particle. Low momentum, slime coating and high reagent consumption are the most frequently discussed difficulties.

CSIRO Process Science and Engineering, Box 312, Clayton, Victoria, 3169, Australia Abstract With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process in an attempt to meet the rapidly growing demand on the

【 Introduction】 There are a lot of in nature, which containes highly quantities of hematite or magnetite.The mainly beneficiation method is magnetic separation and separation,so the mainly used equipments are machine, magnetic separatior,efficient thickener,press filter,slurry pump,feeder, agitation tank and belt conveyor etc.

Fine particles generally refer to sludge smaller than 18 microns or smaller than 10 microns. Because the fine-grained particles mineral mud have the characteristics of small quality and large specific surface area, the particles are caused in the of slurry adjustment and .
