Abstract
The feasibility of extracting metallic values in the form of chlorides from low grade multimetallic lean ores using SO2, O2 and NaCl as reactants is analysed from a thermodynamic point of view. Gangue materials such as silica and alumina do not react. The oxides of most other metals react to form chlorides. The volatile chlorides can be condensed. The chlorides present in the condensed state can be leached. An efficient separation of the metallic values from the gangue is possible using a combined sulphation-chlorination roasting process. Use of sodium chloride as a chlorination agent is attractive because of its non-toxic nature.
