OVERVIEW
Tin (Sn) is used primarily for improving the properties and characteristics of other materials. Its main uses are in metal container coatings and in solders. Bronze and brass alloys and fine chemicals account for most remaining consumption. The element is preferentially concentrated by magmatic differentiation processes and shows a strong affinity for granitic rocks; especially late stage pegmatite differentiates. Most of the worlds tin are extracted from mineral cassiterite of which the largest sources are placer deposits derived from these rocks.
In Zimbabwe, cassiterite has been produced from numerous pegmatite and the elluvial deposits overlaying them. The Dett-Kamativi inlier in the west of the country contains the most important area of tin mineralization with Kamativi mine having dominated national production then. The Wankie Tin Belt extends from west of Tshontanda to east of Kalinda, a distance of more than 70km. The strike overall is east-north-east. Tin bearing pegmatite in mecaceous schist country rocks occur throughout this distance, albeit mining activity has tended to be concentrated on clusters of pegmatite’s at five main centres, namely from west to east, Tshontanda, Kapata, Lutope and Kalinda.
Samples taken across 9 spots of the mining claims yielded collectively 58% Sn to 60% Sn.
