Abstract
It is described a process for extracting aluminum from aluminum-bearing materials comprising the steps of leaching the aluminum-bearing material with HCl to obtain aluminum chloride; separating and purifying the aluminum chloride; providing aluminum chloride to an electrolysis cell comprising an anode connected to a source of hydrogen gas delivering the hydrogen gas during use to the anode, and a cathode; passing an electric current from the anode through the cathode, depositing aluminum at the cathode; and draining the aluminum from the cathode.
Claims22
A process for extracting aluminum from an aluminum-bearing material comprising the steps of:
- a. leaching the aluminum-bearing material with HCl to obtain a leachate containing aluminum chloride;
- b. providing said aluminum chloride to an electrolysis cell comprising an anode connected to a source of hydrogen gas delivering the hydrogen gas during use to the anode, and a cathode;
- c. passing an electric current from said anode through said cathode, depositing aluminum at said cathode;
- and
- d. draining the aluminum from said cathode.
