• Comminution an overview ScienceDirect Topics

    Comminution is needed for the liberation of low-grade ores so that the iron content can be upgraded by gangue removal. This necessitates grinding to such a size that the iron minerals and gangue are present as separate grains.

    How to use comminution processes for reducing the ore

    For example, suppose we have an iron ore of 0.5 meters, and the liberation size is about 400 microns. We need to reduce its capacity to 80% less than 440 microns, at least. If we try to conduct the comminution in one single stage using a mill, we will have several problems. First, the

    Comminution modeling using mineralogical properties

    01.09.2017· Iron ore samples of different grade and texture have been tested. • The specific rate of breakage changes when the particle size approaches the mineral stone size. • The mineral liberation distribution is depending on mineral by size patterns as a function of grades and stone sizes. Abstract. Comminution modeling aims to predict the size and liberation distribution of mineral particles and

    Schematic of a typical lump iron ore production process. Typically, the run-of-mine iron ore will undergo primary crushing, which is normally carried out in jaw or gyratory crushers. Afterward, secondary crushing is done using cone crushers. Other types of crushers can be used depending on the hardness and grindability of the ore.

    Comminution modeling using mineralogical properties of

    Focusing on iron ore samples the study showed how the particle breakage rate decreases when the particles reach the stone size of the main mineral component. Below that size, comminution does not increase mineral liberation and therefore in most of the cases passing over that boundary is only a waste of energy. The study involving iron ores from Malmberget and

    Methods of Ore Pretreatment for Comminution Energy

    Some minerals require a lot of applied power and residence time before showing heating or comminution-type effects. Example: Goethite hydrated iron ore. The iron mineralogy heats, but the bulk ore must heat to a point to where the -OH (water) is released. Line 73 Make sure you are clear that it is granites being described, as per the reference.
