Tungsten Recycling: An Overview Matmatch

The zinc process: This process involves exposing tungsten carbide scrap to molten zinc and zinc vapour in the presence of argon or nitrogen at furnace temperatures of 800 °C to 1050 °C for a prolonged duration of time. The liquid zinc reacts with the binding metal (copper, nickel or iron), which bloats the scrap as the binder volume increases.
