Molybdenum distribution is closely related to magnetite/hematite-Fe and S. The magnetic separation results indicated that Mo and Cu were enhanced in magnetic products by 34–41 and 15–21%, respectively. Cleaner non-magnetic residues were found to decrease significantly by 37–44, 58–60, and 11–19% for Cu, As, and Cr, respectively.
For example, the STEINERT FinesMaster directly combines two serial magnetic separators with one eddy current separator, producing an incredibly efficient and compact machine solution. And for fine-range separation work, we offer the high-gradient magnetic separator STEINERT HGS, a compact system developed as a single- or multi-stage …
Copper slag (CS) is a solid waste that is rich in Fe and Cu and is generated in the process of copper smelting [28, 29]. The production of 1.0 ton of Cu is estimated to produce 2.8 tons of CS [30], and the International Copper Study Group predicted that the worldwide production of CS reached about 55 million tons in 2021 [31].
To comprehensively reuse copper ore tailings, the recovery of γ-Fe 2 O 3 from magnetic roasted slag after sulfur release from copper ore tailings followed by magnetic separation is performed.

An innovative technology for direct reduction-magnetic separation with the addition of Na 2 CO 3 and CaO was studied to upgrade copper slag assaying 40.33% Fe total and 0.65% Cu. It is difficult to recover iron and copper from the slag by direct reduction since the iron mainly occurs in fayalite and the copper exists in copper sulfide.
Since the distribution of helpful metal minerals in the slag is complex, there is often continuous metasomatism, and weakly magnetic fayalite accounts for a large proportion of the slag; the magnetic separation effect is unsatisfactory. Magnetic separation is often used with other copper slag beneficiation methods.
