  • Patent number: 3937667
    Abstract: In conventional processes for separating metals by selective precipitation, the precipitate is frequently in an amorphous form, eg a slime, which is difficult to filter, wash and handle generally. In the present process mixed solutions and/or sols of the metals are mixed with a suitable soluble organic polymer to form a viscous mixture. The latter is formed into discrete entities, e.g. drops, which are contacted with a reagent which converts each drop to a gelled entity containing at least one of the metals as a precipitate.In one form of the process, the same chemical reagent also serves to dissolve the other metal present in the initial drops. The metals are then easily separated by separating the gelled drops from the reagent. In another form, the reagent includes two different chemical reagents which contact the drop simultaneously, one to precipitate one metal in the gelled drops and the other to dissolve the other metal.
