The magnetite concentrate used in this study was collected from an ore dressing plant in China; its chemical composition is listed in Table 1.As can be seen from Table 1, the primary element was Fe, and the grade of iron was 64.86%, which is much lower than that of high-purity magnetite and iron scale.The predominant impurity was …

The current study analyses three iron‑carbon alloys with different superheats, produced as powder by water atomisation and compares the particle shapes and porosity in each. The alloy with the most carbon (4.2 wt%) showed the highest circularity (0.72) for 20–45 μm particles, but the lowest (0.59) for 180-212 μm particles.

Effective purification of cold-rolling sludge as iron concentrate powder via a coupled hydrothermal and calcination route: From laboratory-scale to pilot-scale | …

A sketch of the Flash Ironmaking process is shown in Fig. 1. A gaseous fuel is partially oxidized with industrial oxygen to generate a reducing gas at 1600–1900 K. Iron ore concentrate is fed from the top, and the reduced iron product can be collected as a solid powder or as a molten bath for direct steelmaking.

Canadian iron concentrate (CIC) can elevate the ferrous grade and lower the contents of gangue components and harmful elements in the sinter. To understand high-temperature characteristics of CIC and typical iron ore, the formation of the melt was calculated mainly through FactSage 7.2, and melt fluidity (MF) test for iron ore fines and …

Agglomeration of iron concentrate powder and rich iron ore powder is realized by iron ore sintering and pelletizing. (1) In iron ore sintering, the iron ore powder, flux, fuel, substitute material, and return fines are made into a mixture with a certain mix ratio, into which an appropriate amount of water is added.

The third reutilisation category purifies CRS as an iron concentrate powder. When the purity of iron concentrate powder is higher than 60 wt%, it can be …

The oxidation of ilmenite concentrate process converts the lower oxides of iron to higher oxides and enhances the subsequent rate of reduction to metallic iron [5]. Therefore, an oxidization pretreatment before the reducing and smelting process is recommended for the Panzhihua ilmenite concentrate [6], [7]. There are many …

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

Furthermore, using the best catalyst, iron concentrate powder, the effect of temperature and gas hourly space velocity was studied, where 900 °C and 3 L/g ·h were determined as the optimized reaction conditions to reach the highest carbon/hydrogen yield. Graphical abstract.
