Hematite iron ore Wholesale price
Converting other iron oxides to magnetite can improve the economics of enriching other oxides. Converting other iron compounds to magnetite, especially in the following cases, can be a good solution for bottling ore. For more information on hematite iron ore, please visit our website.
What is the percentage of iron in hematite?
If the ore has been exposed to severe weathering, it consists of different types of trivalent iron oxides, which have completely different properties than the primary oxide from which they are formed. For example, the weathering of hematite can be converted to martite and various aqueous hydroxides. Typically in a ventilated rock there are different types of minerals, each of which has different properties in terms of filling, and the extraction of each of them requires a special method of filling, and with a single method this cannot be he mined the ore Stones. In this case, converting all of these minerals to magnetite can eliminate the complexity of the mineralization method and use only one method (low field magnetic separator) to fill this aerated rock.
– Grain distribution of contamination with hematite The very fine distribution of impurities in hematite or the distribution of fine grains of hematite in the ore band means that advanced comminution is required. In this case, many physical mineralization or flotation methods lose their effectiveness, or the recovery efficiency of these methods is greatly reduced. Therefore, converting the oxidized mineral to magnetite and using a low-field magnetic separator in another method may be the answer. – Mineral siderite Siderite is in the form of iron carbonate and in industry it sometimes needs to be calcined before use. The mineral calcination in the oxidizing medium siderite turns into magnetite during the calcination and thus facilitates the subsequent mineralization.
Hematite ores, which have been crushed to about 3 to 10 mm, are fed into the rotary kiln with reducing agents and are located at the other end of the burners. The burner flame is more or less regenerative. Hematite inside the furnace is partially regenerated and removed from the furnace. The furnace exhaust gases are also released after dusting in a cyclone.
The product removed from the furnace is crushed together with the dust obtained in the cyclone and then filled with a weak-field magnetic separator. The amount of reducing agent must be carefully controlled. If the amount exceeds the required limit, the reduction process can continue and lead to the formation of divalent iron oxide (Fe1-xO), which has practically no magnetic properties. The product leaving the furnace must be cooled quickly or in the absence of air to prevent reoxidation of the magnetite and its conversion to hematite.
