| After the palladium salts are recovered by filtration, they are redissolved and reprecipitated to form a pure salt, and this is converted to metallic form, usually by chemical reduction with formic acid. |
| It is soluble in boiling hydrochloric acid, but it is not reprecipitated by water, as is the case with cuprous chloride. |
| But it is reprecipitated unaltered by excess of alkaline oxalate. |
| These may be reprecipitated and incorporated into authigenic materials, such as glauconite, various carbonates, and iron and manganese oxides. |
| The metal is redissolved in aqua regia, then reprecipitated with ammonium chloride and calcined to pure metal. |
