Sulfur attaches to metal ions, creating a number of significant sulfide ore minerals such as galena (lead sulfide), pyrite (iron sulfide), chalcocite (copper sulfide), and sphalerite (zinc sulfide). Mined sulfur is mostly from salt domes or bedded deposits. The vast majority is produced as a byproduct of oil refining and natural gas processing.

Materials. The asreceived chromite ore was sieved, and the size fraction of 75105 µm was used for the experiments. Table 1 represents the chemical composition of the chromite ore of this specific size fraction, based on XRF analysis. XRD analysis (Fig. 2) shows that the chromite ore is mainly composed of chromite, with minor amounts of clinochlore (Mg,Fe) 5 Al(Si 3 Al)O 10 (OH) 8 ...

Abstract In this paper, the reduction of chromite ore by coke was investigated by means of thermogravimetric analysis under nonisothermal conditions (from room temperature to 1823 K). The fractional reduced samples were examined by SEM/EDS and Xray diffraction analyses. The experimental results showed that the reduction of iron in the chromite ore started before that of chromium in the ore ...
