Importance of iron ore grade
The grade of iron ore refers to the mass fraction of iron in iron ore,that is to say,the iron content. For example, the grade of iron ore is 62, refers to the mass fraction of iron 62%.Commonly the highest grade of hematite is 70%,Magnetite’s highest grade is 72.4%; Siderite’s highest grade is 48.3%; Limonite’s is 62.9%.If the iron ore grade is less than 40% which belongs to the low grade,will have less exploitation value at present.
Processing method for low grade iron ore
The low grade iron ore cannot be used directly and needs to be upgraded to increase the iron content and reduce the gangue content.Usually,for low grade iron ore processing, the ore smelting into steel after grinding.The main difference compare with the way of high grade ore processing is that the low grade iron ore abrasive particles is more thin.For the high-grad iron ore deposit which is the high grade iron ore,there no need to grinding but can be direct smelting.For the low grade iron ore,it need a finer grinding then preliminary screening and smelting.
low grade iron ore dressing machine
Based on many years experience for mining equipment production,Xuanshi recently launched a new generation magnetic separator,specially in processing of low grade iron ore.
To the low grade iron ore,the machine make it possible to obtain a high grade iron concentrate.The specific process is as follow.
Firstly iron ore materials after grinding mill send to classifier for size classification.This just remove a part of the larger impurities.What about the smaller?Then,Send the low grade iron ore into the Xuanshi Magnetic Separator Machine.Choose the wet or dry method According to local water supply and setting positive or negative magnetic separator.With its high separation factor,advanced structure and reliable operation,Xuanshi Magnetic Separator Machine will maximize the iron ore grade.
