Definitions
- This invention relates particularly to the extraction of magnesium from magnesium alloys.
- the magnesium content of the alloy may be of more value or more in demand than the alloy itself.
- the purpose of the invention therefore is toprovide an inexpensive and practical method for effecting the separation of the magnesium from other elements with which it has been combined.
- Magnesium is one of the few metals that completely resists or is unaffected by the alkalis; metals as zinc, on the other hand, readily reactwith an alkali.
- the invention involves the subjection of. the alloy to treatment in a molten alkali which causes the zinc orother metal in the treated alloy to react with the alkali and in the course of the same reaction the magnesium to separate'itself from the other metal or metals and remain dis-- associated from'the' alkali.
- a bath of molten alkali whichmay be either sodium hydroxide or potassium hydroxide is prepared in a kettle of cast iron or other suitable material and brought to.
- alkali reacts immediately with the alkali into zincate and hydrogen and the neu.
- trality of the magnesium for the alkali results in the magnesium, in the presence ofi nascent hydrogen, separating in a practically' pure state and floating to the top, where it can be readily removed.
- the process of extracting magnesium from magnesium containing allo s which ten alkaliand the introduction into such comprisesthe preparation of a bat of mol-f bath of the magnesium containing alloy in condition and quantity to; control the exothermic action resulting from such combination.
