The invention discloses a separation method of zinc ash in smelting zinc dross. The separation method comprises the steps of dross airing, sorting, sieving of 35-45 meshes, conveying through a belt conveyer, crushing and screening separation: (1) the dross smaller than 0.5 mm is separated out by a screen of 38-50 meshes before the crushing; …

However, no cost-effective recycling methods have been reported to date. Therefore, this work aims at developing a novel method for Al–Zn alloy recovery from an industrial 55%Al–Zn dross using supergravity separation. The separation efficiency was analyzed as a function of separation time and temperature as well as the gravity …

The 106µm particle size dross brick can serve as acid refractory because its properties compared well with medium-alumina fireclay and exhibits relatively low cold crush strength. The study on the physio-mechanical behavior of aluminum dross has been carried out. The amount of aluminum dross used varied between 50 and 90 wt %, while …

Extraction of Tin/ Stannum. Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue. Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

After metallic aluminum content is separated, white dross (AWD) is used as raw material of this work. Separation is done by crushing and milling, and lastly collecting the NMR part from vacuumed bag filters. Prior to calcination experiments, raw materials are characterized by using sieving analysis, X-ray diffraction, and chemical analysis.

Aluminium metal recovery by electrostatic separationElectrostatic recovery of metallic aluminium from dross has been studied by Mah et al. (1986) who developed a circuit which involved first crushing the dross to − 840 μm. They achieved a recovery of 70% of the metallic aluminium at a concentrate grade of 70% Al.

Crushing of aluminum dross into smaller particles usually displays the heterogeneity inherent in the dross. Due to the higher viscosity of metallic aluminum as compared to other brittle oxides and nitrides, the size of the crushed particles of metallic content remains larger. ...

The Al extrac-tion rate from aluminum dross (AD) reached 86.21%, the denitrification rate reached 99.54%, the concentration of soluble fluoride ion was reduced to 0.111 g·L−1, and the fluoride fixation rate was 75.04 wt%. CaF2 is the main component of the leaching residue, which can be added as an insulation material for electrolysis.
