Magnetic Separation Of Iron Ore

The production process of iron ore mainly include: crushing, grinding, ore dressing. In the crushing process, three crushing circuits are suitable for high hardness iron ore broken, which can complete the ore crushing and partial dissociation work so as to improve the efficiency of the subsequent grinding.

In grinding process, two sections of a closed grinding is efficient grinding process, which can make the iron mill more fully. In the new process, the representatives of emergence successful processing technology in recent years are: "stage grinding, low intensity magnetic separation and reverse flotation technology", "magnetic separation", "ultra-fine crushing wet magnetic separation tailings process".

Magnetic Separation Machine

SBM has produced several thousand Low Intensity magnetic separators both dry and wet versions to the iron ore and others mining industry. SBM has (in close co-operation with the iron ore mining Industry) developed and designed the low intensity magnetic separators to meet the highest demands for capacity, metallurgical performance and mechanical availability.

Magnetic separation machine has the best performance in practice. It is equipped with the most technologically advanced high intensity magnetic separation equipment. This machine has reached the double advantages of high concentrate grade and high yield in separating magnetic ores.

Introduction Of Iron Ore

Iron ore is an important raw material for iron and steel enterprises. Ore, which contains iron or iron compounds, can be called iron ore. Iron is selected from natural ore (iron ore) by crushing, grinding, magnetic separation, flotation, gravity concentration process. Iron exists in the nature in a compound state. Iron oxide is the most common form in the nature as well as with the most impurity substances. For example, hematite, magnetite, siderite, limonite, etc.

Application Of Iron

Iron is the most widely used of all the metals, accounting for 95% of worldwide metal production.Its low cost and high strength make it indispensable in engineering applications such as the construction of machinery and machine tools, automobiles, the hulls of large ships, and structural components for buildings. Since pure iron is quite soft, it is most commonly combined with alloying elements to make steel.

Commercially Available Iron

Commercially available iron is classified based on purity and the abundance of additives. Pig iron has 3.5–4.5% carbon[59] and contains varying amounts of contaminants such as sulfur, silicon and phosphorus. Pig iron is not a saleable product, but rather an intermediate step in the production of cast iron and steel. The reduction of contaminants in pig iron that negatively affect material properties, such as sulfur and phosphorus, yields cast iron containing 2–4% carbon, 1–6% silicon, and small amounts of manganese. It has a melting point in the range of 1420–1470 K, which is lower than either of its two main components, and makes it the first product to be melted when carbon and iron are heated together. Its mechanical properties vary greatly and depend on the form the carbon takes in the alloy.
