Indian mining industries primarily depend upon high-grade fines mainly because of two factors, one is lack of beneficiation infrastructure and high cost of low-grade fines, the second one is lack of proper tail disposal system. Due to lapses in our policies, miners get better premium by selling high-grade fines over low-grade fines. This …
The iron-making process requires high-quality raw materials, with Fe ≥ 64% and <2% alumina and silica each, to enhance blast furnace productivity at a given energy consumption rate.
Simple systems with constant feed can use flocculant pump speed control, more advanced control systems utilize a ratio controller to maintain a constant "grams per ton" dose rate. Unfortunately, fluctuations in ore type can significantly change the dosage of flocculant required and require a feedback to the "grams per ton" constant.

With the mining of mines and the continuous development of the iron and steel industry, iron tailings, as a kind of beneficiation waste, are also increasing in storage. Iron tailings are solid wastes discharged after extracting iron ore concentrate from iron ore.
In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. …

Dalli - Rajhara Iron ore complex is the existing captive iron ore source of Bhilai steel Plant(BSP).It includes Dalli manual mines,Dalli mechanized mines, Jharandalli mines,Mahamaya mines, and Rajhara mechanized mines. ... Rejects of slime beneficiation plant will be disposed after pressure filtration in the form of solids (containing around 20 ...
The tailings from iron ore beneficiation processes contain some iron-bearing minerals; therefore, recovering iron minerals from these tailings can lead to a reduction in the volume of tailings and thus reduce their environmental effects, and on the other hand, it leads to economic benefits and protection of mineral resources (Di Maria …
In the beneficiation plant, the thickener is widely used in the thickening of pulp and tailings, so that the backwater can be recycled and the concentrate is dewatered before filtering. Thickeners can be widely used in the treatment of sludge, wastewater, and waste residues in metallurgy, mining, coal, chemical, building materials ...
This work describes the concentration of iron ore slimes on a pilot scale by using a 500-mm diameter flotation column and a novel collector, which renders the use of a depressant unnecessary. The pilot column was operated in series with the industrial plant Vargem Grande 2 (Iron Quadrangle, Brazil) receiving, as feed, part of the underflow …
Herein we present our case study on plant scale with a paste thickener. We have chosen the partial beneficiation mode and operated on 24 × 7 basis without …
Cliff's Tilden plant in Cleveland, USA, is the only iron ore beneficiation plant, where selective flocculation technique, using degraded starch as the flocculant, has been applied to produce pellet grade concentrate from a feed containing around 32% Fe . The plant has a capacity of processing 10 million tons and is in operation since 1975.

In India, the tailings of iron ore beneficiation are dumped in slime ponds, which is a major environmental concern. In the present study, a new beneficiation circuit was designed to recover the valuable minerals from the tailing effectively. The present study involves the characterization of three different samples using chemical, particle size, …

The depletion of high grade iron ore resources make it inevitable to utilize the existing low grade iron ores/fines/tailings with effective beneficiation to meet the present specification and demand.
The tailing of the iron ore beneficiation plant (containing 17% iron) at a mass flow rate of 300–350 t/h in slurry form with 5–8% w/v solids% is usually dewatered in two parallel thickeners (D = 55 m, H = 6.6 m).
