World iron ore production

World iron ore production was 1.1 Mt, a 4% increase compared with that of 1999 (table 17). Although iron ore production was widely distributed, taking place in about 48 countries, the bulk of world production came from just a few countries. The five largest producers, in decreasing order of production of gross weight of ore, were China, Brazil, Australia, Russia, and India. The United States and Canada were 6th and 8th. The top five accounted for 70% of world production.

China was the largest producer in gross weight of ore produced, but because its ore was of such low grade, the country’s output ranked well below Australia’s and Brazil’s output in Fe content. Of the largest producing countries, India experienced the highest growth, increasing 7% over production in 1999.

Iron ore production line

The majority of the iron ore that is mined can be used for making steel. So we need the extraction of the pure metal from its ore. The extract the metal through ores, several physical and chemical methods are employed. The method used depending on chemical properties and nature from the ore from which it will be extracted. Iron ore production line entails four main steps:

1. Crushing and grinding of the ore.

2. Concentration or dressing of the ore.

3. Reduction to free metal.

4. Purification or refining of the metal.

It’s important to choose different iron ore crushers for different requirements. In order to achieve higher production efficiency, Shenbang design a more efficient iron ore crushing and screening process:

Within the iron ore production line, in order to make how big iron ore materials as fine as you possibly can before entering into milling equipment, the iron ore crusher should have an excellent fine crushing capacity to reduce iron ore size. To achieve this crushing impact, two grades of jaw crushers and something fine crusher (high slender breaker machine) are applied within the iron ore crushing process. Two types of jaw crushers tend to be coarse and fine jaw crushers. Tertiary fine crushing machine may be the key for the complete iron ore production line.

Iron ore mining equipment

The main crusher is Jaw crusher and also Cone crusher. Our jaw crusher can achieve the crushing ratio of 4-6 and also the shape of final product is actually even. They are widely applied in order to crush high hardness, mid hardness and soft rocks and ores for example slag, construction materials, Iron ore, etc. The pressure resistance strength is actually under 200Mpa, that is, suitable for iron ore primary crush. It can be used within mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.

Grinding can be a powdering or pulverizing process while using rock mechanical forces of impaction, compression, shearing and attrition. Main machines in ore milling process are ore mill equipment. The most common iron ore grinding mills in mining are ball mill, Raymond mill and high pressure suspension mill.
