how do benefication take place in iron ore industry

Oct 23, 2010 The amount of alumina and silica in iron ore must be below 2 pct to make the ore suitable for the steel and iron industry. However, each source of iron ore has its own peculiar mineralogical characteristics and requires a specific beneficiation treatment depending on the nature of the gangue present and its association with the ore structure

    This invention relates to an improved method of beneficiating iron ore by froth flotation. The problem of iron ore beneficiation has been a serious one because of the low unit value of the product and the fact that, while it is not difficult to float various iron minerals, the procedures employed have resulted in insufficient recovery of concentrates sufficiently rich in iron ore to be

    Malcolm Tatum Raw ore deposits have to be crushed and processed. The processing of iron ore is a task that involves taking the raw ore and preparing it for use in the creation of a number of different iron products. There are actually several different processes that may be used to aid in this conversion of the raw ore into useful iron components

    Iron ore sintering and pelletizing are the predominant processes in the iron-making industry [1,2]. During the iron ore sintering process, calcium ferrite phase is believed to be the most desirable bonding phase because it has high reducibility and sufficient mechanical strength [3–5]. The sintering process can be divided into three
