Tungsten carbide is one of the strongest materials known and is widely used in machine cutting tools. However, the amount of tungsten available worldwide is limited and finite. This is why tungsten recycling is just as important as tungsten processing from the point of view of the industries that rely on the material.

It is hard to trace back to when and where the first chemical processing of tungsten scrap took place. However, the early chemical fusion in bath processes, which were developed for tungsten concentrate processing, already used the addition of oxidising alkali salts, such as chlorate and nitrite, to the sodium carbonate or sodium hydroxide melt ...
