Therefore, the exploration of low-energy and high-efficiency low-grade iron ore treatment processes is necessary.
In this case, gravity separation is feasible, as the concentration criteria are between 1.75 and 2.73. The copper grade has been increased from 0.48 to 5.33%, with 26.14% recovery . To justify this result, the authors have performed preconcentration via gravity separation using a bench-scale table for the Malanjkhand copper sample.

Much of the remaining iron ore resources in Brazil consist of low-grade itabirite ores. Accordingly, a typical beneficiation circuit includes a four-staged crushing/screening plant, followed by grinding in a closed-circuit ball mill, desliming in hydrocyclones and final ore mineral concentration via multistage reverse flotation and thickening of the final product.
The residual carbon in CGFS is mostly recovered using gravity-separation, flotation, and chemical-separation methods. The residual carbon and ash components of the CGFS have different densities; consequently gravity separation enriches residual carbon by exploiting this difference (i.e., density separation) (Zhang et al., 2020).

Weakly magnetic iron ores, such as hematite, need to be treated by a combined process of high-intensity magnetic separation and other separation methods. Some mines of Ansteel Group Corporation used a single method in the early treatment of hematite, such as single-stage flotation or single strong magnetic separation, gravity separation, etc.
The earliest beneficiation machinery was gravity separation equipment. The earliest piston jig was commissioned in Germany in 1830–1840 and was used for metal ore separation. Flotation machine appeared later with the first flotation machine (mechanical agitation type) appearing in 1910.
