AfriTin: Turning tin tactic to tech
AfriTin's production capacity stretches beyond Uis – and for the more immediate horizon includes two ore bodies in relatively close proximity to Uis, namely the 35 000 ha Brandberg West and the 33 000 ha Nai-Nais. Both have historically already revealed tin and tungsten and tin and lithium content respectively.

Settling behavior of tungsten tailings using serpentine as flocculant
In tungsten flotation, a large amount of water glass is usually added. However, water glass also has dispersion effect on the slurry and makes the settling of tungsten tailings difficulty [26]. The objective of this study is to determine if serpentine can be used as a flocculant for the settling of tungsten ore and the result could provide ...

Tungsten: Properties, Production, and Applications
Tungsten is a transition metal known for its outstanding properties, especially when combined with other elements in compounds such as tungsten carbide. The name Tungsten was derived from the Nordic words "tung" and "sten", which combined mean "heavy stone" [3]. Tungsten is also known as wolfram, from which it takes its chemical …

Tungsten Metallurgy | SpringerLink
Tungsten metallurgy is the technology that extracts the tungsten metal from tungsten ore raw materials. In 1781, the Swedish chemist C.W. Scheele separated a new oxide from scheelite and named it tungstic acid. In 1783, the Spanish chemists J.J. Elhuyar and F. Elhuyar, who were brothers, separated tungstic acid from wolframite.
