The beneficiation of iron ore deposits to yield haematite and magnetite concentrates for steel making processes typically require the use of one or a combination of wet processing techniques based on gravity, magnetic or froth flotation processes. With the need for more cost-effective technologies with a lower water demand, a re-examination of dry
The Coaltech Research Association plans to further evaluate a new, dry dense medium separation (DMS) process later this year at a pilot plant at a coal mine in Witbank. Since mid-2015, Coaltech ...
The triboelectrostatic beneficiation is an advanced dry fine coal cleaning technology and can effectively process fine coal of less than 300 μm (Dwari and Hanumantha Rao 2008; Zhang et al. 2009). During the process of triboelectrostatic separation, coal particles are charged by contact or friction with other particles or with a third material ...
A novel dry beneficiation technology for pyrite recovery from high sulfur gangue. It is of significance for the environment protection, the shortage of water and the economic benefits to recovering the pyrite from the gangue with high sulfur content (GHSC) by the vibrated fluidized bed. In this study, characteristics such as the sulfur form of ...

The current FGX version for dry beneficiation of coal was developed in China by prof Y Y Song, and has reportedly many commercial applications in China [Honaker (93)(94)] Figure 6.1 FGX dry coal separator [Honaker (95)] The coal on which this technology has been applied is Laurasian coal, with low near
The slimes fraction (714) from the secondary air classification system (705) may be further processed with suitable technology, including BSS. The dry, bauxite-depleted co-product fractions (713, 709) are suitable as an input to the manufacture of portland cement or cement clinker or may be stacked as dry tailings or moisture conditioned tailings.
The RTS technology is a triboelectrostatic separation process with unique features and is effective in concentrating phosphate by increasing P 2 O 5 grade and reducing MgO content. 2. Applying a negative potential to the rotary charger greatly enhances differential charging of phosphate, quartz, and dolomite. 3.

coal processing in the form of dry density-based beneficiation technologies using gas−solid fluidized beds by FRASER and YANCEY [2]. Since then, studies related to these methods have been performed in many countries around the world. Magnetite powder
The STET tribo-electrostatic technology has been used to process and commercially separate a wide range of industrial minerals and other dry granular powders. Here, bench-scale results are presented on the beneficiation of low-grade Fe ore fines using STET belt separation process. Bench-scale testing demonstrated
The recovery rate of 3–6 mm, 1–3 mm and 0.5–1 mm were 75%, 65.64% and 71.45%. The results of XRD and XPS showed pyrite was the foremost mineral in the concentrate with the highest proportion. The study indicated that combination technology could be effectively used for pyrite recovery from high sulfur gangue.
Thermal beneficiation also eliminates ammonia issues and can improve fineness and uniformity. Successful thermal beneficiation technologies have been commercially deployed since 1999 (Keppeler, 2001). This technology produces more than a million tons of marketable fly ash per year in the eastern United States.
