The common tungsten extraction methods are surface (or open pit) mining and subsurface (or underground) mining, or a combination of both. Modern tungsten processing methods dissolve scheelite and wolframite concentrates by an alkaline pressure digestion, and tungsten can also be recycled from Scrap.

1 Chapter 17. Processing of Metal Powders Introduction This chapter describes the powder metallurgy (P/M) process, in which metal powders are compacted into desired and often complex shapes and sintered (heated without melting) to form a solid piece. This process first was used by the Egyptians in about 3000 to iron tools. One of its first
