- Abstract
- The paper provides a review of the studies performed, starting from the 1970 up to today by Italian National Councils Mineral Processing
Institute, to develop application for the use of chelating reagents in the flotation of metallic minerals.
A summary is given of the various phases through which the studies progressed, starting by employing commercial reagents and then
moving on to the synthesis of new long-chain chelate collectors for the flotation of sulphide and oxidized Pb, Zn, and Cu minerals.
In particular a description is presented of the thermodynamic and structural criteria to be followed in designing and synthesizing chelate-
type collectors with optimal structure for a given metallic mineral.
A theoretical method has been developed for choosing chelating groups that exert selective action on one metallic mineral rather than
others. The theoretical approach is based on thermodynamic data of the chemical equilibria in solution.
Moreover, the flotation results obtained in the flotation of oxidized and mixed ZnPb ores, by using chelating reagents with a mixed
aliphaticaromatic structure, provided interesting pointers for designing the non-polar portion. The structural criteria identified via these
studies were interpreted on the basis of chemical and steric considerations.
Recently, the thermodynamic approach was adopted to identify selective reagents for the removal of minor elements and for the separation
of copper from zinc in the xanthate flotation of complex sulphide ores. (literal)
