Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
Iron Ore Pelletization Technology and its Environmental .

Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is always preferred. Indian ...
For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

Abstract and Figures. This paper addresses the modeling of the iron ore direct reduction process, a process likely to reduce CO2 emissions from the steel industry. The shaft furnace is divided ...
Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.
A fullscale plant trial of the substitution of a specific organic binder for bentonite was conducted in the company's straight grate pellet plant in Quebec, which produces Mtpa of pellets, 36% of which are used as feedstock for the DR process. The results of the fullscale pellet plant trial are given in Table
The reason iron ore pellets are preferred to iron ore powder is air flow in blast furnaces, if the iron ore was powder than CO would not be able to pass up through the layers in a blast furnace. ...

Charging the blast furnace/ BOS plant Pellets are primarily used in blast furnaces and are also used in DRplants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material)
The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from Mta capacity to 28 Mta in the forthcoming years.
The pelletization process for magnetite ores can be broadly categorized into three subprocesses raw material preparation, balling and induration, a schematic of process flow is shown in Figure 3 ...
What are particles? Iron ore pellets, like concentrates, are raw materials for the manufacture of iron, which is pulverized and ground into pellets ranging from 0 to 100 microns for supply to industry as pellet feed. Green pellets and hardened green pellets are used in the direct reduction process to produce iron.

Abstract The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.

Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram. Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control are fundamental to the process.
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.
The shaft furnace (Figure 2) is the core of the DR process. Iron ore pellets are charged at the top, descend due to gravity, and encounter an upward counterflow of gas. The reducing gas (CO and H 2, plus CH 4, CO 2, and H 2 O, at about 950 °C) is injected peripherally at midheight and exits at the top. In the lower section of the furnace, of ...
