Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel.


An important part of the comminution circuit is size classification. This can be accomplished with screens or cyclones or a combination of the two. Since cyclones classify on the basis of both particle size and specific gravity, cyclone classification in the grinding circuit directs coarse siliceous particles to the cyclone overflow.


For design purposes, you need an estimation or prediction of your SAG Mill's tonnage; well, there are 3 ways to generate good rock "ore" hardness testing data for SAG and ball mill circuit grindability from half drill core.

COMMINUTION - THEORY AND PLANT PRACTICE A. Das and S. Roy INTRODUCTION Comminution is a major unit operation in iron ore processing. In terms of global quantities of material reduced in size, it has been estimated that the annual tonnage is of the order of several thousand million, and in terms of the energy expended the


For a high-grade iron ore deposit (ie greater than 62 per cent), a dry crushing and sizing process is sufficient to achieve the required product quality and size fraction as lump ore, sponge ore or sinter fines (MetalBulletin, 2014).


Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...

Feb 24, 2015· A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates eco-efficient alternatives for the process design for magnetite iron ore.


An important factor in both comminution and sizing operations is the determination of the particle size distribution of the materials being processed, commonly referred to as particle size analysis. Many techniques for analyzing particle size are used, and the techniques include both off-line analyses which require that a sample of the material ...

Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in consumer demands. Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores.
