Die Ermittlung des FirmenwertesThe continuation of a systematic electron microprobe study of the platinum-group minerals occurring in ore samples from the Ivrea-Verbano basic complex (Western Italian Alps), has led to a better definition of the range of solid solution in the NiTe.-PdTe.-PtTe. ternary field.

The Potential for Hydrothermal Platinum Deposits similar to that of gold, the ratio of p1atinum:gold recovered by mining operations is about 1:20. The shortfall is in platinum recovered from mineral deposits in which the ore components have been transported in aqueous solutions at temperatures below 400°C.
