Copper tailings: if the copper with high heavy metals content, the separation will be easier and apply the process of flotation. If there exist magnetite in the copper tailings, it will firstly using acid leaching to precipitate the copper, then use magnetic separation accordingly.
Arsenic (As) is commonly associated with Cu ore minerals, with the resultant risk that As can be released offsite from mine tailings. We used synchrotron-based fluorescence X-ray absorption near-edge spectroscopy (XANES) imaging to provide in situ, laterally-resolved speciation of As within tailings which differed in magnetite content (5–12%) and organic matter content (0–5%).

The copper and magnetite recovery plant and associated service facilities will process run of mine ("ROM") ore delivered to a primary crusher feeding a conventional process of crushing and grinding of the ROM ore, copper flotation, and magnetite recovery from copper rougher tailings.
In 1993 Craigmont Mines commenced the recovery of magnetite from the mill tailings. Since the commencement of that operation, Craigmont Mines has produced in excess of 600,000 tonnes of media grade magnetite product. Approximately 450,000 tonnes of proven reserves are present in the remaining unmined tailings deposit.
Tailings thickener in copper ore beneficiation. A tailing of copper flotation process contains iron sulfur and other elements, magnetic separation process obtained a unqualified products, because the grade of iron concentrate is only 60%, but the grade of sulfur is 2%, and the grade of SiO2 is 13.67%.
The historic Craigmont Copper Mine operated for twenty-one years, prior to closing in 1982 because of $0.60 lb. copper prices. Operations then shifted to twenty-one years of magnetite production, which focused on extracting magnetite from historic tailings. It's logical to combine the economic value of both copper and magnetite for this project.
