Prior to its use, it is briquetted for ease of charging. The tests are carried out in a regular, commercial basic oxygen steelmaking furnace (160 ton batch, and duration about 45 min). Substitution of lump ore (with slime briquette) in various tests has been.
Typical Indian iron ore slime in a steel plant contains 56 iron, 6.78 Al(2)O(3) and 5.8 SiO(2). Value addition to this reject waste material has been investigated using chemical treatment and electrowinning. Two alternate chemical treatment routes have been explored (i) acid extraction of iron followed by alkali treatment and (ii) alkali.The generation of iron ore slimes in India is estimated to be 10-25 by weight of the total iron ore mined – the iron ore values are lost to the tune of 15-20 million tones every year. In addition, these slimes stored in massive water ponds poses enormous environmental hazard.

This slime or sludge is noticeable in the toilet tank when the lid is removed. The organisms occur naturally in shallow soils and groundwater, and they may be introduced into a well or water system when it is.
Iron ore slime is which has the particle size of below 150 m is being discarded as waste during the mining and processing stages iron ore and it will be stored at the tailing dam. It is estimated that 18 - 25 of tailing will be generated during the processing of iron ore. Treatment of iron ore slime for value addition. www.sciencedirect.com.Oct 20, 2015 FTIR test was performed on iron ore slime sample to find out the presence of functional groups. The FTIR spectrum of iron ore slime is shown in Fig. 3. It is reported in the literature that peaks around 410–415, 450–470, and 670–680 cm −1 showed the presence of hematite.
Earlier work with iron ore and iron ore fine slime indi-cates that beneficiation of iron ore and fine slime containing very low iron and high alumina and silica is quite difficult. Also, it is equally difficult to know the characteristic proper-ties of the particles where most of the population is below 50 micron.Iron and Manganese 1 Iron and Manganese . Iron and manganese control is the most common type of municipal water treatment in Minnesota. Iron and manganese occur naturally in groundwater. Neither element causes adverse heath effects at concentrations typically found in Minnesota. These elements are, in fact, essential to the human diet.
Silica in iron ore leading to slime generation which are disposed of in tailing ponds. Slime in these tailing ponds contains iron values in the range of 45-60 .
