comminution process in iron ore

COMMINUTION THEORY AND PLANT PRACTICE

Tumbling mills Grinding i is the last stage in the process of iron ore comminution; in this stage the particles are reduced in size by a combination of impact and abrasion, either dry or in suspension in water. It is performed in rotating cylindrical steel vessels known as tumbling mills.

How to use comminution processes for reducing the ore

Comminution processes refer to crushing and grinding operations, which are used for reducing the size of ore. Usually, the as mined material from the earth is a combination of rocks, lumps, and particles. Therefore, it should be comminuted to liberate valuable minerals from gangue and then separating them into two products; a concentrate and a tail.

Developments in iron ore comminution and classification

01/01/2015· HPGR technology was introduced to the mineral processing industry in the mid-1980s and has rapidly (for the mining industry) established itself as the convention in the comminution of cement, clinker, slag, iron ore, iron pellet plant feed, and diamond ore. There are now approximately over 500 machines operating in these applications. The operating history is reported to be good with few

COMMINUTION THEORY AND PLANT PRACTICE

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 yearly megawaa hours total several hundred million. Top product size ranges from a few centimetres in crushing plants to a few microns in very

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 capacity will be deficient. We can not process a large volume of the ore to reduce its size from 0.5 meters to
