Leaching of Aluminium Dross in Alkaline Solution

2017-3-8  aluminium dross can by dissolved and not all amount of aluminium oxide reacts with NaOH. Leach-ing residue finally consists of spinel (MgAl 2O4) and non-leached aluminium oxide. In general, it is possible to state, that there is a lack of detailed information and experimental work dealing with alkaline leaching of aluminium dross.

Aluminium recovery during black dross hydrothermal

2013-6-1  Aluminium was dissolved as sodium aluminate from black dross by treatment with NaOH at high pressure. Alkali leaching experiments were carried out in an Inconel autoclave reactor of 600 mL maximum capacity with pure nickel protective linings. Temperature was controlled using an external heating mantle with a

Aluminium recovery during black dross hydrothermal

Comparing the acidic leaching with alkaline leaching of aluminium dross, it is found that the NaOH leaching process can extract around 57.5% aluminium present in the dross (Tsakiridis et al., 2014

Black Dross Leached Residue: An Alternative Raw Material

2014-7-11  Black Dross Leached Residue Chemical and Mineralogical Characteristics. The chemical composition of the leached residue, at the optimum leaching conditions is given in Table 1.Its main mineralogical phases, detected by X-ray diffraction analysis, are presented in Fig. 1, together with the corresponding analysis of the initial aluminium black dross (ABD).

Production of Alpha-Alumina from Black Aluminum Dross

2020-7-27  The aim of this work is to produce α-alumina particles from aluminum (Al) dross via leaching–precipitation–calcination processes. In the leaching test, the effects of parameters such as the temperature, NaOH concentration, and time were investigated based on the Taguchi approach. In addition, the effect of the particle size on the Al extraction rate was determined. The Al extraction rate

Study on the Extraction of Aluminum From Aluminum

2018-7-20  The aluminum dross was crushed and ground, then dried at 433 K (160 °C) for 24 hours for further use. The following is an elaboration of the multiple procedures adopted, i.e., water leaching, extraction of aluminum by alkali roasting, purification, and mesoporous γ-alumina synthesis (illustrated with a

Characterisation of aluminium black dross before and after

Aqueous leaching to recover salts from black dross is accompanied by hazardous gas generation. The gas-generating phases vary significantly across differently sourced black dross. The challenge for the industry is how to accurately qualify and quantify the problematic components of black dross, espe
