This document was prepared by Technical Committee ISO/TC 102, Iron ore and direct reduced iron, Subcommittee SC 1, Sampling. This fifth edition cancels and replaces the fourth edition (ISO 3082:2009), which has been technically revised. It also incorporates the Technical Corrigendum ISO 3082:2009/Cor.1:2009. The main changes compared to the ...

The scheme of the iron ore sintering process is represented by Fig. 5. Sinter mixture contains iron ore, solid fuel (usually coke breeze), flux and some additives (e.g. solid wastes like BOF slag, gas cleaning dust and sludge etc.). The mixture is granulated with the addition of moisture and loaded to the travelling grate of the sintering plant.

Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. During the iron ore …

The first iron objects came from space, before the advent of smelting. ... the carbon in the wood would also have reacted with oxygen in the ore, converting it to carbon dioxide and freeing the ...
