Iron ore production scheduling to improve product quality ...

Iron ore quality depends upon successive shipments being uniform in composition, not only in iron but also in several other minerals. The production process involves several stages of scheduling, from the mine face, through railing, stockpiling and ship loading.

Iron Ore Analysis Process Optimization Solutions ...

To efficiently process iron ore for high quality steel production, frequent ore grade monitoring, during all steps of downstream processing, is mandatory. Independent from the ironmaking method, the optimal use of fuels and energy during sintering, pelletizing and direct reduction of iron ore (DRI) needs to be applied to stay competitive and produce environmentally friendly.

Influence of Coating Granulation Process on Iron Ore ...

In recent years the improvement in the quasi‐particle structure with the granulation process is an effective method for improving sinter quality and productivity. To improve the sinter quality and productivity for low grade iron ore fines, different granulation processes like the conventional one, and other two advanced granulation processes like coke breeze, and flux coke breeze coating granulation were studied in

3D Stockpile Modelling to Improve the Quality Control in ...

Abstract-This paper describes a 3D stockpile modelling algorithm to improve quality control and increase operational efficiency in iron ore handling. The 3D model, generated from real measuring data, approximates a stockpile using a group of 3D volumetric element, which able to store information inside it, such as quality compositions of the ore.

Global Drivers for High Grade Concentrate Magnetite

Iron is extracted from iron ore in a blast furnace by a process known as reduction. The raw materials – iron ore, coke and fluxes – are fed into the top of the furnace. Air, which is heated to about 1200°C, is blown into the furnace through nozzles. The air causes the

Iron ore subjected to that temperature does not melt, but instead results in a spongy mass (called "sponge" iron) mixed with impurities called slag. The iron worker removed this spongy mass from the furnace and then squeezed the slag out of it by hammering. This "wrought" iron had less tendency to corrode and had a fibrous quality from the ...
