in many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. the first step of many separation processes is comminution size reduction followed by classification separation by particle size either for further grinding or the next step, concentration of the ore.
this document specifies the methods to be employed for determination of size distributions by sieving of iron ore and direct reduced iron excluding briquetted iron , utilizing sieves having aperture sizes of 36 µm or larger. the size distribution is expressed in terms of mass and percentage mass, passed or retained on selected sieves.

furnace size has increased markedly, however, and one large modern furnace can supply a steelmaking plant with up to 10,000 tons of liquid iron per day. throughout the 20th century, many new iron-making processes were proposed, but it was not until the 1950s that potential substitutes for the blast furnace emerged.
water addition, particle size distribution, ore porosity, surface properties of the iron ore and wettability of the iron ore by water are the most important factors that affect the granulation efficiency and permeability of the green sinter bed10 14. the permeability of the sinter bed in turn controls
