  • Process for the extraction of precious metals from solutions thereof
    Patent number: 4390366
    Abstract: A process for sequentially and selectively separating gold and platinum group metals from aqueous solutions containing them is disclosed.First, ruthenium and osmium are oxidized to their tetroxides and then removed from the solution. Then, gold is removed by solvent extraction preferably with dibutyl carbitol. Next, palladium and platinum are removed by solvent extraction with an alkyl sulphide and tributyl phosphate respectively, care being taken to reduce iridium in solution before platinum extraction to prevent it extracting with the platinum. Then the iridium is reoxidized and removed from solution. Finally, rhodium is removed from the solution.Using this process gold, platinum and palladium of saleable purity can be extracted directly without the need for further refining steps.

  • Process for producing lithium-metal master alloy
    Patent number: 4389241
    Abstract: Master alloys of lithium or other alkali metal with a second metal such as alumium are made by exposing mechanically aloyed powder of the second metal to molten alkali metal.
