As a dispersed element, cadmium is difficult to enrich and mineralize. As the Cd tetrahedron is similar tothat of Zn in covalent radius and crystal structure, both the elements possess similar geochemical habits.Cd is present mainly as isomorphous impurity in sphalerite. So Cd, as an associated element, occurslargely in Pb-Zn deposits. Current research both at home and abroad is focused on the environmental effect of Cd, but little work has been done on the mechanism of enrichment and mineralization of Cd. Theresearch papers available are mostly restricted to the ordinary geochemical characteristics of CdFrom the end of 1980s to the early 1990s, independent ore deposits of Te, Tl and other dispersed elements were discovered in the region of Southwest China. Prof. Tu Guangzhr proposed that dispersed elements can form their independent ore deposits.
