For sulfide ores, a different process is taken for beneficiation. The ore needs to have the sulfur removed before smelting can begin. Roasting is the primary method of separating, where wood was placed on heaps of ore and set on fire to help with oxidation. 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2

 · The latter property aids in the beneficiation of magnetite ores. Magnetite contains % Fe by molecular weight, which is higher than hematite, but magnetite ores having lower ore grade (generally 2030% Fe) owing to the presence of impurities. This results in higher costs for the production of concentrate for steel smelters. Large magnetite deposits occur across Australia and, in 2018 ...

 · Hematite, weakly magnetic iron ore with better floatability than magnetite and wide distribution, is one of the most important raw materials for ironmaking.. Its composition is complex. In addition to containing a small amount of magnetite, the impurity embedding of hematite has uneven particle size and high content of fine particles, which often requires some beneficiation processes.
