  • Patent number: 4141960
    Abstract: Bimetallic salts, having the generic formula MM'X.sub.n wherein M is a Group IB metal, M' is a Group IIIA metal, X is a halide and n is equal to the sum of the valences of M and M', are prepared by reacting the halogen salts of the individual metals, M and M', in a suitable solvent. The bimetallic salt formed thereby is a discrete monomeric species and can be utilized in the separation and recovery of various ligands, by preferential complexation. Complexation can be conducted with the bimetallic salt in the solid state, in solution, or as a slurry, and with the complexible ligand in the gaseous or liquid state. The ligand is recovered by decomplexation of the bimetallic salt-ligand complex or by displacement of the complexed ligand with another ligand.

  • Patent number: 4049438
    Abstract: Manganiferous deep sea nodules containing non-ferrous metal values are selectively reduced to reduce manganic oxides to manganous oxide (MnO) and the non-ferrous metal values to the metallic state, and the selectively reduced nodules are then smelted to produce a molten metallic alloy containing the non-ferrous metal values and a slag containing most of the manganese. The molten alloy is blown with a free-oxygen-containing gas to eliminate most of the manganese, and the substantially manganese-free metal is then sulfided to produce a matte suitable for separation and recovery of the non-ferrous metal values. After sulfiding the matte can be blown with a free-oxygen-containing gas to lower the iron content thereof. Not all the iron is removed if it is advantageous to keep a high proportion of cobalt in the matte.
