Iron Ore Pellet - an overview | ScienceDirect Topics

The MIDREX process is a shaft-type direct reduction process where iron ore pellets, lump iron ore or a combination are reduced in a Vertical Shaft (reduction furnace) to metallic iron by means of a reduction gas (see Figure 1.1.39) [9].

Prospects for Coal-based Direct Reduction Process

The reduction reaction kinematic for conventional pellets and sintered ore is controlled by reduction gas diffusion from outside. On the other hand, the reaction of carbon composite agglomerates occurs inside the agglomerates themselves, which consist of iron ore fines and pulverized coal. Once the agglomerates are heated, carbon monoxide is

Direct reduced iron - Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

"DR Grade Pellet Quality, Supply and Prices"

•direct reduction processes: – chemical change is removal of oxygen from ore – remaining constituents stay with direct reduced iron product but increase in concentration due to the removal of oxygen – these affect process economics of subsequent EAF melting vessel • Blast furnace, smelting reduction processes – formation of refining slag allows modification of hot

Iron and Steelmaking - vsb.cz

A blast furnace charge consists of ore, fluxes and fuel. The ore part of a charge consists of iron ores and concentrates, manganese ores and various types of scrap containing iron. These ore parts are usually contained in a charge as products of a high-temperature treatment i.e. as agglomerate or pellets. Agglomerate currently

The Process - Plant - Texas LLC

Direct Reduction – The cleanest and safest way of iron making. Most naturally occurring iron oxide has the composition of hematite (Fe2O3) and contains about 30% oxygen. The direct reduction process removes this bonded oxygen in the iron ore pellets at elevated temperatures by a reducing gas, which is produced from natural gas.

Pelletizing - Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...
