Iron ore sintering is one of the key steps in the ironmaking process, where granulated pellets are transformed into sinter in the sintering machine, providing an ideal raw material for ironmaking blast furnace. Drum granulation in the sintering process plays an essential role in determining the final sintering performance.

Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, lead and zinc. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal behind.

What we see is that the various iron oxides are turned into iron in several steps, always producing FeO or wüstite first. The first two reactions (roasting) you can do separately from smelting, you sort of condition your ore. Reduction of the wüstite is the final reaction in the smelter, it produces the elemental iron.

During this process the water content of the iron ore is released, and its structure becomes looser, which makes it easier to smelt. Finally, we break up the burnt iron ore into 23 cm pieces to make it easier to load the iron ore into the furnace during the smelting process (See Figure 3). Step 3. Building furnaces.

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Smelting. Smelting is the general term for getting a metal from its natural ore. Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.
