| titleOfInvention | Two sections of sedimentations refine platinum technique |
| abstract | The invention discloses two sections of sedimentations and refine platinum technique, it comprises: (1), hydrazine hydrate reduction: add water platinum concentrate pulp, is warming up to 50 ± 5 DEG C, adds hydrazine hydrate and ammonium chloroplatinate is reduced into platina; (2), aqua regia dissolution: the platina leached is put into glass cylinder and to be added water pulp, adds aqua regia dissolution until platinum is molten to the greatest extent; (3), one section of non-oxidation sinks platinum-boil molten palladium: control solution platiniferous 50g/l, be warmed up to 60 DEG C, adds NH4Cl and sinks platinum, after reaction terminates, and heated and boiled, cooled and filtered, washing; (4), two sections of heavy platinum palladiums of oxidation: one section of heavy platinum filtrate is warmed up to 60 DEG C, adds the ammonium chloride of 10:1 and sodium chlorate and sink platinum palladium, after reaction terminates, cold filtration, washing; (5), the molten palladium of ammonification: will filter after one section of platinum salt obtaining and two sections of platinum palladium salt use pure water pulp respectively, (6), calcining: the platinum salt putting into porcelain crucible, at retort furnace heating and calcining, takes out washing and drying after Slow cooling. |
