Mn in recycled aluminium

The experimental works have been carried out to enhance the properties of recycled aluminium scraps by the addition of manganese. The following are the main hypothesis:
1. Despite numerous works claiming to use manganese in aluminium scraps, none of the experimental works have carried research on scraps and the experiments were carried out on alloys by addition of the impurities.
2. The dissolution of manganese in aluminium is very low but the published works claim higher dissolution of manganese even when added in the form of powders
3. Experimental works have been limited to the 1, 2 and 5 kg furnaces and the experimental works are not projected to higher loads and thus irrelevant for real-time applications in the industry.
The present work focuses on recycling aluminium troma scraps and enhancing the qualities of recycled aluminium troma scraps by adding manganese to the scrap melts. This work is carried out to extend the works carried out by (Zhijun Zhang, 2013) on recycled aluminium alloys. Most research trials have been directly conducted on aluminium scraps with the exception of the works of Puga et al. (2009), who carried out research works on recycling aluminium swarfs and Xiao et al. (2012) who investigated the recycling of distributed turning scraps.
