The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive

Bakalskoye deposit (Russian Federation). The parameters of sintering process as well as the characteristics of sinter were extensively studied. An addition of the magnesian iron ore concentrate to the sinter mix in the amount of 10 wt. % on a blended ore basis resulted in the following changes in the course of the process and the sinter quality:

High-quality iron ore sintering process is ensured with advanced equipment from Thermo Scientific for all aspects of iron and steel production and manufacturing. ... enter the Mining Toolkit App and find the latest equipment and technology for your mining operations!

Intensification of the iron ore sintering process is approached with a four-way framework covering granulation improvement, waste gas recycling, fuel gas injection into the sinter bed, and reduction of stack emissions. Various metallurgical wastes are granulated to form micro pellets and are dosed along with the feed to cut down the cost.

The selective granulation process is a new sintering process for high alumina iron ore fines, and can eliminate the adverse effects of 'hard to sinter' or 'unsuitable – for ironmaking' ores. In the present work laboratory sintering experiments have been carried out with iron ore fines of different alumina level (2.00 to 5.46 mass ...

Iron ore sintering involves the movement of a flame front down a particulate bed, and a series of physico-chemical reactions over a large temperature range.

Iron ore sintering is an energy-intensive process associated with emission of pollutants in iron and steel industry. In order to comprehensively evaluate the environmental impacts of sintering, a detailed life cycle assessment of a sintering plant was conducted. ...
