Iron Ore Pelletization: Part I. Fundamentals

The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet. Meeting these requirements leads to the …

Iron Ore Pellets and Pelletization Process

Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. 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 ...

AP-42, CH 12.5: Iron And Steel Production

The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix, and then placed on a continuous, travelling grate called the …

Development of a Novel Grinding Process to Iron Ore

The moisture and, consequently, balling control have a starting point at the comminution process, where several types of equipment is applied in iron ore operations.

Iron Ore Pelletizing Process: An Overview

The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives —anthracite, dolomite—and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2.

DR-Grade Iron Ore Pellets – A Supply Overview

The creativity of DR plant operators, ingenuity of process suppliers, and expertise of iron ore pellet producers assure DRI products keep pace with demand.

Beneficiation of Iron Ores

This is carried out by the processes of beneficiation of the iron ore. Beneficiation of the ore is the process where ore is reduced in size and gangue is separated from the ore. Since each of the iron ore deposit has a unique mineralogy, the beneficiation process is specific to each deposit.

Pelletization

The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization: .

Malmberget Pelletizing Plant, MK3

Schematic picture of the Malmberget Pelletising Plant, MK3. As the picture shows, the pelletising plant is divided into different zones where the main task is to dry, fire and cool the iron ore pellets. The direction of the flow of ambient air, gas streams and exhaust gas is marked with arrows in Figure 3.

Direct reduction of pellets through hydrogen

The iron ore pelletizing plant begins with the grinding process, where the ore is mixed with a specific solid content and grinding balls of varying sizes. The plant has multiple ball mills, each with a considerable capacity to process the ore.

Dry beneficiation of iron ore

Falling prices for iron ore with lower quality than 60 % Fe have led increasingly to the design of iron ore beneficiation lines. General problems of water scarcity and risks with tailings dams have led to the focus shifting to dry beneficiation technologies. In the following article, current developments are examined and case studies referenced.

Disc Pelletizers (Pan Granulators)

DISC PELLETIZERS. FEECO's Disc Pelletizers (also known as pan granulators) are the equipment of choice for converting powdered materials into uniform, round pellets. Disc pelletizers utilize a non-pressure (tumble growth) approach to agglomeration and work by tumbling material on a rotating disc, with a binding agent and feedstock being ...

Exploring Steel Production: A Comprehensive Visual Process Chart

The chart starts with the raw materials like iron ore, coke, and lime being melted in a blast furnace to produce molten iron. Molten iron is then processed in a basic oxygen furnace where it is converted into steel by adding scrap metal and alloys. The final stage on the chart shows the casting process where steel is formed into various shapes ...
