Application of topological indices to froth-flotation of an uranium ore

Topological indices, namely Wiener index, Randic's connectivity index and the information index based on distances are used to describe the molecular structure of a series of alkylcupferrons used as mineral collectors in the beneficiation of a Canadian uranium ore. There is a linear relation between any of these topological indices and the separation efficiency of the alkylcupferrons considered. The data fit into two separate curves, differentiating the alkylcupferrons into two subclasses, one with rigid rod-like methyl substituents and the other with flexible alkyl substituents.
