It can be seen that DHDAB have better separation performance for hematite and quartz than DTAB, when the collector dosage was greater than 15 mg/L. The optimal dosage of the two collectors was 20 mg/L, and the recoveries of quartz and hematite with DHDAB were 96.25% and 15.20%, respectively, with a difference of 81.05%.

In this context, a low-grade hematite ore with 56.5% Fe has been subjected to heat treatment followed by grinding and wet high intensity magnetic separation (WHIMS). The magnetic separation results indicate that an enhancement in yield by around 15–20% by weight is possible when the ore is heat-treated at 500–800 °C.
