ABSTRACT:
According to the invention a process is proposed for purifying low-melting metals from impurities, residing in that a melt of a low-melting metal is treated with an aqueous solution of an inorganic acid or an alkali in the presence of organic compounds with ionogenic groupings.
The proposed invention enhances the purity degree of the low-melting metal being purified and at the same time reduces the losses thereof.
