Iron ore is a important material for steel industry.The natural iron ore,generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), and siderite (FeCO3).when Ores carry some quantities of hematite or magnetite ,for example 62%, the ore's grade is known as 62..which means that the ores percent is 62.
Iron is the world's most commonly used metal - steel, of which iron ore is the key ingredient, representing most of all metal used per year.t is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications (machinery).The Iron ore reserves at present in our country seem quite vast, but the math of continual exponential increase in consumption can even make this resource seem quite finite.because it is unrecoverable.And the quality of iron ore in our country is not very high so that it is very essential to improve the efficiency of the Utilization.Some application of the ore compound: iron sulfate can be used as a fungicide in the field of photography.limonite,and goethite, can work as pigments and abrasives, in the area of industrial production for magnetite hematite ,iron electrode and oxalic acid.Iron chlorides and nitrates can be seen in the production of various types of inks and industrial reagents. Carbonyl iron as a catalyst use in chemical reactions. As a protective coating,mica, hematite plays an import role in the steel constructure .
The processing technology always includes the use of vibrating feeder, jaw crusher, vibrating screen, ball mill, classifier, magnetic separator, concentrator and dryer and other major equipment components, such as the elevator, conveyor. These equipments can build up a complete production line.This ore processing production line features of high efficiency, low energy consumption, high capacity and low cost.it takes use of a new technology which will increase the quantities of hematite up from 35% up to 68～70%,elevating the Utilization rate of iron ore to 90%.During the processing, the consumption of water will decrease.,that will cut al lot of cost .at the same time ,the dust pollution will be held a lot.
