In the High cadmium telluride case, demand for cadmium and tellurium grows sevenfold by 2040 in the SDS to 1 300 tonnes and 1 400 tonnes respectively. This rapid growth would put pressure on supply capacities, as current production levels are around 23 000 tonnes for cadmium and 500 tonnes for tellurium.

The orange and blue lines represent the fractionation factor (α Cdsol.-CdS) between ore-forming fluid and cadmium sulfide, which is 1.00028 and 1.00052 due to different salinity (Guinoiseau et al., 2018), respectively. Although the large fractionation factor (1.00052) can match data in Jinding, this is obtained in an extreme case (pure …
