For a long time, charcoal was the form of carbon used in the reduction process. The production and use of iron became much more widespread about 1620, when coke was introduced as the reducing agent. ... The furnace is charged with alternating layers of iron ore (largely Fe 2 O 3) and a mixture of coke (C) and limestone (CaCO 3). …

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.

Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has …

The SR process typically involves two reduction stages, prereduction of iron ore at its solid state and final reduction and melting of the partially reduced iron ore in liquid state. The SR process produces liquid pig iron by direct use of coal, and its product can be treated and refined in the same way as the hot metal (liquid pig iron) from ...

ABSTRACT. 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.
