In situ X-ray diffraction may be used to examine the relative effects of alumina sources gibbsite, kaolinite, and aluminous goethite on the formation and stability of key iron ore sinter phases, SFCA and SFCA-I. Iron ores containing aluminous goethite and kaolinite maximise the formation of these important sinter bonding phases. This explains why sintering investigations using Australian ores containing kaolinite …

Iron processing | Britannica

Throughout the 20th century, many new iron-making processes were proposed, but it was not until the 1950s that potential substitutes for the blast furnace emerged. Direct reduction, in which iron ores are reduced at temperatures below the metal’s melting point, had its origin in such experiments as the Wiberg-Soderfors process introduced in Sweden in 1952 and the HyL process introduced 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. By associating this model with the cutting geometry of a real …

A review of ironmaking by direct reduction processes ...

01/01/2019· Overview of DR processes Direct reduction processes reduce iron ore (in the form of lumps, pellets or fines) to the solid state using a reducing gas to produce Direct Reduced Iron (also known as sponge iron). DRI is often compacted to reduce its porosity and to convert it to Hot Briquetted Iron (HBI) for sale or storage (Indian Bureau of Mines, 2011). Depending on the source of reducing gas, DR …

IRON ORE SINTERING PART 2. QUALITY INDICES AND …

Improvements in the blast furnace process are achieved by technological improvements and a stable supply of high quality iron ores and sinters [1]. However, high quality iron ore resources are being depleted due to the heavy demand, and thus it is necessary to continue improving sintering technology in order to use lower quality iron ores in the raw mix. The blast furnace demands sinter with high …
