Solid residues are generated at various stages of metal production. Some of these residues still contain significant quantities of metals. In determining possible process routes for residues a detailed knowledge of the mineralogy (i.e. the minerals or phases present) is required. This thesis examines the mineralogical characteristics of four residues: copper smelter dust, jarosite residue and hot-acid-leach residue all from the metallurgical plant of Kidd Creek Mines Ltd., and low-acid-leach residue from the Canadian Electrolytic Zinc plant. / The methodology of characterization included the fractionation of the residues based on particle size, magnetic susceptibility and leachability in sulphuric acid. The fractions were analyzed by X-ray diffractometry and electron beam techniques. / A major phase in all the residues was zinc ferrite. The characterization of this phase showed that it does not have the stoichiometric composition of ZnFe$ sb2$O$ sb4$ but exhibits a variable composition of the type Zn$ sb{x}$Fe$ sb{3-x}$O$ sb4$. This variable composition corresponds to a measured variation in magnitude susceptibility of the ferrites. / Some treatment routes for these residues are examined; special emphasis was placed on the potential application of magnetic separation. The hot-acid-leach residue appeared the most amenable to magnetic separation.
