The Sangdong Mine, which has one of the world's largest tungsten deposits, is poised to produce up to 15% of the global tungsten supply once fully operational. The mine's tungsten grade of 0.45-0.50%, more than twice the global average of 0.18% [7], ensures its competitiveness. Almonty's development efforts at Sangdong also aim to address ...

This study focused on tungsten secondary minerals in tailings generated during a two-year mining operation at the Mount Pleasant Tungsten Mine, approximately 60 kilometres (37 mi) south of Fredericton, New Brunswick. Initially, the tailings were submerged but were exposed to atmospheric oxygen following a dam failure in 1997.
An adit (from Latin aditus, entrance) [1] or stulm [2] is a horizontal or nearly horizontal passage to an underground mine. [3] Miners can use adits for access, drainage, [4] ventilation, and extracting minerals at the lowest convenient level. [1]
