This International Standard specifies the methods to be employed for determination of size distributions by sieving of iron ore, whether natural or processed (e.g. concentrates and agglomerates, such as pellets, sinters or briquettes), utilizing sieves having the aperture size of 45 μm and over.
In this International Standard, the terms "iron ore" or "ore" shall refer to all the above-mentioned types of materials.
The sample of iron ore is subjected to sieving procedures for the purpose of determining the size distribution of the con-stituent particles. The size distribution is to be expressed in terms of mass and percentage mass, passed or retained on selected sieves.
The methods described in this International Standard are equally applicable to size determination utilizing one, two or several sieves.
