The Challenge of Tungsten Skarn Processing by Froth Flotation: A Review

Autor: Yann Foucaud, Lev Filippov, Inna Filippova, Michael Badawi

Publikováno v: Frontiers in Chemistry, Vol 8 (2020)

Recently, tungsten has drawn worldwide attention considering its high supply risk and economic importance in the modern society. Skarns represent one of the most important types of tungsten deposits in terms of reserves. They contain fine-grained sch
