 · The reduction of iron oxides takes place according to the following chemical equations: (1) F e 2 O 3 + 3 C O → 2 F e + 3 C O 2 (2) F e 2 O 3 + 3 H 2 → 2 F e + 3 H 2 O In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 °C. The iron ores are therefore not melted!

 · The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13].Corresponding to each temperature interval, …

The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group of iron-making …

 · The iron ore processing and production process refers to the production process in which the mined iron ore must be processed and produced by various operations to obtain concentrates that meet the smelting requirements. Mainly include: ore crusher crushing and vibrating screen screening, ball mill grinding and classifier classification; mineral …

 · According to production practice research, weak magnetic separation methods are often used to separate them. In a medium-sized magnetic separation plant, the ore is demagnetized and then enters the crushing and screening workshop to be crushed to a qualified particle size, and then fed to the grinding workshop for grinding operations ...

1、Single magnetite. The composition of single magnetic iron ore is simple, magnetic strong, easy to wear and separation, so weak magnetic separation method is often used. ·When the grinding size is greater than 0.2mm, most iron ore magnetic separation plants usually adopt a grinding - magnetic separation. ·When the grinding particle size is ...

 · The processes used for removing the gangue from the ore are based on the differences between the physical or chemical properties of the gangue and the ore. Different separation techniques are accordingly employed. 1. Extracting Metals Low in the Reactivity Series. Metals low in the activity series are very unreactive.

 · The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

It is suggested to adopt the combined process of weak magnetic separation and flotation, that is, the weak magnetic separation process is used to recover iron first, and then the …
