Agnico Eagle Kittilä gold mine in Finland commissioned such a unit – reported to be one of the first mine in the world to do so. One of the drivers in their approach was a 30% higher annual production target. Kittilä mine uses the sub-level stoping mining method. The average stope height is 25m but can be as high as 40m.

The reprocessing trials using gravity separation and bioleaching demonstrated promising results, suggesting both techniques could effectively recover resource and decontaminate the mining waste. The gravity separation reprocessing test has successfully recovered 48.4% W from the tailings, with the resulting W concentrate achieving a 21.6% WO 3 ...

Wolframite is the principal and primary ore mineral of tungsten, and commonly associated with the tin ore in and around granite country rocks. Wolframite is an iron manganese tungsten oxide {(Fe.Mn)WO 4} mineral.The mineral crystallizes in monoclinic system with perfect cleavage, and occurs as massive dark gray to brown-black color and submetallic shining luster (Fig. 1.51).

The purpose of the Contract was to explore and run mining operations of wolframite (WO3) within a permit named "Gifurwe".

Direct dating of W and W Sn deposits by wolframite is more reliable relatively to gangue mineral and important for understanding their timing and genesis. However, such analysis still lacks of homogeneous wolframite standard recently. Due to containing considerable and variable common lead, and inhomogeneous in different grains, the wolframite sample of MTM, …
