At the same time, the increasing dependence on high-quality iron ore and the depletion of coking coal resources are also the limiting conditions for the continuous production of BF ironmaking [1, 2]. In the traditional BF ironmaking process, sintering and coking are production processes that are extremely polluting to the environment.

Smelting Reduction. Figure 2: The smelt reduction vessel (SRV) is the core technology component of the Hismelt process. Source: RioTinto While years of ironmaking technology innovations have optimized blast furnace productivity, two alternative processes—smelting reduction and direct iron reduction— are growing in adoption. The …

The global growth in demand for raw materials is leading to a continuous increase in the mining of ores and thus to an expanding volume of tailings to be stored. To ensure safer storage and an optimized recovery of process water, the tailings slurry is often thickened followed by filtration in filter presses and dry stacking. However, an …

The partially reduced ore is then smelted in the second unit, and liquid iron is produced. Smelting-reduction technology enables a wide range of coals to be used for iron making. Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments.

The high‑silicon IOTs used in this experiment were provided by a mineral processing plant in northern China. The samples were dried and then grounded to 45 μm, and their chemical compositions measured by XFR were summarized in Table 1.The sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), and hydrofluoric acid (HF) used in this …
