The reactive milling time used was 5 h in a ball mill, for a ball/dross mass ratio of 6.5. For a molar relationship of 1:3 (Al 2 O 3 /CaO), sintered products with calcium aluminate contents of over 90% were obtained, in which tricalcium aluminate (C 3 A) was the majority compound (87%), followed by C 12 A 7 (5%).
The present work examines the synthesis of tricalcium aluminate (for use as a synthetic slag) from the non-saline dross produced in the manufacture of metallic aluminum in holding furnaces. Three types of input drosses were used with Al2O3 contents ranging from 58 to 82 wt %. Calcium aluminates were formed via the mechanical …

In terms of production volume, aluminium is the leading metal in non-ferrous metallurgy. In particular, the recycling of aluminium-containing residues has strongly increased in recent years and will continue to gain importance in the future. Due to the high affinity of aluminium to oxygen, the oxidation of the molten bath is unavoidable, which …
An example of mechanical cleaning is the dry milling process. Cold aluminum-laden dross and other residues are processed by milling and screening to obtain a product containing at least 60 to 70 percent aluminum. Ball, rod or hammer mills can be used to reduce oxides and nonmetallic particles to fine powders for ease of removal during screening.
Among them, the aluminum dross ball mill belongs to the beneficiation equipment with excellent performance and professionalism. Compared with the traditional ball mill, it has more advantages, more unique features, and to a certain extent it can reduce the difficulty of the user's work. This article introduces the equipment in detail from the ...
Aluminum dross (AD) is a hazardous waste that contains valuable metallic Al and reactive aluminum nitride (AlN). The intergrowth of Al and AlN presents a challenge to Al recovery and AlN removal. In the current work, a mechanical milling method was developed to separate Al and AlN. Steel bars and balls were used as grinding media. …
