Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores. If present, cobalt, tantalum and niobium are recovered in separate processing lines. Other tungsten containing scrap and residues might require a modified process.

2020-6-18 Working with Tungsten. Processing. Grayish-white in color, tungsten metal is not found “standalone” in nature. Instead, like many ores, it must undergo an extraction process in order to be in a usable form for manufacturing. But unlike some ores, tungsten cannot be extracted and refined using traditional smelting processes.

2019-10-1 Tungsten, as a strategical rare metal, is one of these critical raw materials. It is an essential component in a wide range of products for many end uses (Lassner and Schubert, 1999, Trasorras et al., 2016, BGS, 2011a, Gunn, 2014).Particularly, the use of tungsten in hard metals represents its most important application.

2018-6-8 Tungsten is of industrial relevance due its outstanding intrinsic properties (e.g., highest melting-point of all elements) and therefore difficult to 3D-print by conventional methods. Here, tungsten micro-lattices are produced by room-temperature extrusion-based 3D-printing of an ink comprising WO 3 –0.5%NiO submicron powders, followed by H 2 ...

2015-8-13 In our past article, we provided an overview of the material known as Tungsten Carbide.In this follow up, we’ll tell you how this key material is made. Tungsten has the highest melting point of all metals, at 3410 o C (6170 o F). In order to create parts made from tungsten or tungsten alloys like tungsten carbide, the typical process of melting and blending of the metal and alloying elements ...
