Extraction and separation of copper and iron from copper

Copper is an important metal widely used in electrical, light industry, machinery, construction, national defense and other fields because of its excellent ductility, conductivity and thermal conductivity (Gbor et al., 2000; Guo et al., 2018b; Potysz et al., 2015).Iron ore is the supporting resource of China's iron and steel industry, which is a Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of The leaching rates of copper from magnetic separation concen-trates and tailings are 28.44% and 26.95%, respectively. The total copper recovery is 87.61%.

Separation of Copper-Molybdenum Flotation Concentrate by

Separation of chalcopyrite from molybdenite is currently mainly carried out by flotation, but this process is costly because of the extensive use of inhibitors. This study briefly describes a 7.0T/100CGC low-temperature superconducting magnetic separator and discusses its separation principle as well as the effect of magnetic induction on Dry permanent magnetic separators have been widely used in the mineral and coal processing industries due to their simple operation and high separation efficiency. These tools not only discard some amount of bulk gangue from the raw ore, thereby reducing the volume of the grinding operation and cutting energy consumption, but also Minerals Free Full-Text Dry Permanent Magnetic

Heap Leaching and Magnetic Separation for Gold-Copper Ore

Gold-copper ore beneficiation methods commonly used in actual production include flotation, gravity separation, electrolytic precipitation, volumetric extraction, magnetic separation, etc. The types of ores applicable to each method are also different. The gold-copper ore beneficiation methods will be introduced below by heap Finally, the treated copper slag was crushed and grinded down to 40 μm, and two fractions were obtained by magnetic separation. The magnetic fraction (85%) was mainly comprised of magnetite, while the non-magnetic fraction (15%) had 5–10 wt. % Cu. Considering the experimental results, 7.5–18 kg Cu/t slag might be recovered from the slag.Metals Free Full-Text Recovery of Copper and Magnetite from Copper

Recovery of Manganese Ore Tailings by High-Gradient Magnetic Separation

With the depletion of high-grade manganese ores, Mn ore tailings are considered valuable secondary resources. In this study, a process combining high-gradient magnetic separation (HGMS) with hydrometallurgical methods is proposed to recycle fine-grained Mn tailings. The Mn tailings were treated by HGMS at 12,500 G to obtain a Mn Process Flow.
