Abstract
Bi-Te melts have potential as Au scavengers in different types of gold deposits. Using phase equilibria, we define ‘melt-(precipitation) windows’ within which the Bi-Te scavenging mechanism can operate. Predicted assemblages correlate well with those in natural samples and can be applied in other cases to explain the distribution of telluride minerals in Au deposits.
