Application of Selective Grinding and Electrostatic Separation of Aluminum Dross as a Pretreatment for Generating Green-Hydrogen
A national project of Establishing Green-Hydrogen (G-H) Society in Honjo-Waseda Area is now being developed by Waseda University together with four other universities and ten companies.The project involves three tasks of technological development of,(1)G-H production,(2)G-H refining,transportation and storage,and (3)G-H utilization.This paper focuses the first task of G-H production from aluminium dross. We developed the physical treatment process by combining selective grinding with vibrating rod mill and electrostatic separation,in order to produce two kinds of materials,one is metal aluminium concentrate to recover it and the other is raw material to produce G-H and aluminium hydroxide which can be generated by the treatment with sodium hydroxide aqueous solution.Here,we described the concentration mechanism of metal aluminium in the selective grinding and electrostatic separation and proposed a separation flowchart for optimizing the G-H system in Honjo-Waseda area.
