Recovery of gibbsite from secondary aluminum production dust by caustic leaching

Sonochemically Recovered Aluminum Oxide Nanoparticles from Domestic Aluminum Wastes as a Highly Stable Electrocatalyst for Proton-Pump Inhibitor (Omeprazole) Detection

“…On the other side, US Department of Energy surveyed that worldwide 10 million pounds of aluminum wastes (mostly domestic) are placed as landfills each year. 4,5 These reports further conveyed that the aluminum reactions could be hazardous during landfill operations by causing uninvited heat, toxic gases, and liquid leachate. 6 A few research groups have reported the recovery of aluminum by various methods.…”

Sonochemical Assisted Leaching of Aluminium Oxide Nanoparticles from Domestic Aluminium Wastes as Non-Toxic Electrode Material for Energy Storage Application

“…Therefore, it is vital to find a facile method to recover or recycle aluminium wastes. [3][4][5] Few research groups have reported various methods to recover aluminum from the wastes, such as smelting based recovery process, density separation method, 6,7 plasma assisted method, 8 hydrothermal treatment 9 and acid dissolution method. 10 Each method has its own limitations like need of costly instruments, reaction condition with extremely high temperature, long time duration and usage of dangerous/carcinogenic chemicals.…”
