Summary. Hematite is a naturally occurring ore of iron, the most common ore of iron and the most used source of iron. It is often sold as red iron oxide. Red iron oxide has many uses from pigments and dyes through to ceramics. Its resistance to heat and antipruritic properties mean that it is often used for casings and coverings.

The samples of the high-sulfurous iron ore were taken from a certain mining area in Inner Mongolia, China and then processed by screening, crushing, mixing and packing with a weight of 1.0 kg per bag.
Iron ore tailings (IOT) were obtained from one source in Johor; a southern State in Malaysian Peninsula. Physical test data showed that it had: specific gravity = 2.6, relative density = 1.27 g/cm 3, fineness modulus = 1.05 and water absorption rate = 7.0%.

This review is a recapitulation of the material characteristics of IOT and its effects on the workability, mechanical properties, and durability of concrete. ... properties of IOT like fineness modulus, apparent density, water ...
The results showed improved properties of iron ore pellets at an optimum Blaine number (2150 cm 2 /g) but, reduction degradation index was found to be very poor for the given ore. Further investigation showed that when MgO containing flux viz. pyroxenite was added, the reduction degradation index and swelling index of the pellets were …
The recovery of iron from the screw classifier overflow slimes by direct flotation was studied. The relative effectiveness of sodium silicates with different silica-to-soda mole ratios as depressants for silica and silicate bearing minerals was investigated. Silica-to-soda mole ratio and silicate dosage were found to have significant effect on the separation …
The Iron Ore and 2 fine pellets survey showed good, desirable properties, at the Blaine no., of 1678 cm 2 /g and 2311 cm 2 /g (corresponding to 200 mesh size), and the best results are attained at a firing temperature of 1300 °C.
The iron ore concentrate with the higher Blaine number causes problem in pellets making [1], [2]. Moreover, it requires the higher grinding energy during preparation to achieve the …

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening ... This index takes into account the material ore hardness and feed size, mill speed, material recirculation, desired fineness, etc. When the material exits the mill, the iron ore is classified using cyclones or ...
The dimension of the fineness index K f coincides with that of specific surface S sp, i.e., m –1, and this specifies material state of comminution, i.e., a value inverse to particle size.With an increase in fineness there is an increase in the role of surface phenomena during sintering. It is seen from calculated results for fineness index of …

In the context of Blaine fineness, Iron Ore No.2 pellets show less porosity due to the finer proportion of grains in concentrates. Blaine 1989, 2311, 2879, and 3461 cm 2 /g contain smaller grains than 44 microns in the proportion 48.2, 53.2, 65, and 78 weight %, respectively. This grain proportion of finer particles affects the porosity of pellets.
