Abstract

A method for preparing Electric Arc Furnace dust (EAFD) for metal recovery, comprising: a) mixing the EAFD comprising zinc oxide or lead oxide, or a mixture of both, with a liquid and a binder to produce an EAFD mixture; b) producing a shaped EAFD pellet; and c) drying the shaped EAFD pellet is disclosed. A method for recovering zinc from Electric Arc Furnace dust (EAFD), comprising: a) heating the EAFD comprising at least one metal comprising zinc in an inert gas atmosphere at a temperature ranging from 700 °C to 1100 °C; and b) evaporating the at least one metal comprising zinc from the EAFD and collecting the at least one metal is also disclosed. A method for recovering an impurity from Electric Arc Furnace dust (EAFD), comprising: a) heating the EAFD comprising an impurity in an inert gas atmosphere at a temperature ranging from 700 °C to 1100 °C; and b) evaporating the impurity from the EAFD and collecting the impurity is also disclosed. A method for recovering iron oxide from Electric Arc Furnace dust (EAFD), comprising: a) heating the EAFD comprising iron oxide and at least one metal in an inert gas atmosphere at a temperature ranging from 700 °C to 1100 °C; and b) separating the iron oxide by evaporating the at least one metal from the EAFD and leaving the iron oxide as a residue is also disclosed.
