A new process for preparing high-purity iron (HPI) was proposed, and it was investigated by laboratory experiments and pilot tests. The results show that under conditions of a reduced temperature of 1075°C, reduced time of 5 h, and CaO content of 2.5wt%, a DRI with a metallization rate of 96.5% was obtained through coal-based direct …

TGA (%) = –0.327 + 0.847KF ( n = 22, r = 0.995), which clearly shows that the TGA losses of mass up to 100°C underestimate the water contents. For the ten iron ores samples, the average moisture determined by the TGA method was 0.18 ± 0.05%, whereas by the Karl Fischer method was 0.50 ± 0.14%. This large discrepancy in the contents ...
