Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.

The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows: Example Calculation A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power.
First, the iron ore, the raw materials for steel, comes from the Earth. Most iron ores — hematite, magnetite, limonite — contain an average of 60% of iron (Fe). Before the iron ores enter a blast furnace, it undergoes 'sintering' which turns the pristine iron ore into more compact and appropriate sizes.

Product 80% passing size (d80) was defined as process response. Grinding experiments were designed and executed by a laboratory ball mill. These experiments were conducted on two feed sizes (480 and 1000 μm).
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …

It can be seen from Tables 1 and 2 that the blend with high iron grade has a high content of FeO (14.51 wt.%) because it consisted of 70 wt.% magnetite concentrate and 30 wt.% fine ore. The coke breeze has high fixed carbon content (83.37 wt.%) and low volatile matter content (1.57 wt.%). 2.2 Methods. The double-layer sintering process is …
In the present work, the effects of some key grinding parameters such as ball size (20–40 mm), grinding time (10–30 min), solids content (65–80%), and also ore work index (12–15.4 kWh/t) on the grinding of some copper sulphide ore were investigated. Product 80% passing size (d80) was defined as process response.

Determine d80 for feed and last cycle undersize (d80 is the screen opening in microns through which 80% material passes). Calculate average grams of undersize produced per revolution for the last three cycles (Gpb). Calculate work index using the second equation. where: X = number of revolutions required. W = weight of original feed.
The following are generalised ore characterisation steps: x Metallurgical analysis of head grades and associated size distribution studies; x A simplistic model analysis may be required. An x-ray fluorescence scan on unknown samples is also recommended. x Suitability of the ore for heavy liquid testing is assessed by the requirement that ...

The size analysis results indicate that the d80 and d50 passing sizes of the sample are 1900µm and 150µm respectively. The Fe content is more in finer sizes with …
Crushing As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size.
The price of the Iron Ore Future depends on several factors, such as the price movement of the underlying assessment of iron ore. Additionally, the potential for profit or loss of the Iron Ore Future position depends highly on the way the position is used, e.g. Iron Ore Futures can be traded as a risk management tool to hedge other investments

required to produce 0.9 Mg (1 ton) of product sinter. 12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel.
The principal iron ores contain hematite (Fe2O3) and magnetite (Fe3O4). Hematiteis an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe by molecular weight. It has been the dominant iron ore mined in Australia since the early 1960s.
