Definitions
- One option to recover aluminium from the hydrochloric acid solution is to use thermal dissociation to drive off water and hydrochloric acid leaving a pure alumina powder for sale as a product and/or for use in electrolysis cells to produce high purity aluminium.
- Another option to recover aluminium from the hydrochloric acid solution is to transfer the aluminium from the hydrochloric acid solution into an ionic liquid electrolyte and produce high purity aluminium metal via electrolysis of aluminium ions in the ionic liquid.
- the form of the electrolysis step depends in part upon the nature of the ionic liquid used.
- One approach with this option is to use a cell which is set up so that aluminium transfers from the aqueous acidic solution into the ionic liquid through an ion selective membrane .
- Another approach with this option is to use a hydrophobic ionic liquid with a high affinity for aluminium that is stable in the presence of water and acid whereby the aluminium transfers into the ionic liquid directly.
- This approach may be assisted by adding chemical additives to the ionic liquid to improve the aluminium affinity of the ionic liquid.
- Chemical additives include, by way of example, complexing reagents to improve the aluminium affinity of the ionic liquid.
- Another option is to separate the aluminium in the form of a solid aluminium-containing material such as alumina, aluminium trihydrate and/or aluminium chloride and dissolve the solid material into the ionic liquid to provide the source of aluminium.
