Zinc Reclaim Furnaces
AVS has developed a zinc reclaim process and furnace systems for the recovery of scrap tungsten carbide. The AVS process uses molten zinc to break down the cobalt bond structure, then the zinc is removed, leaving a friable tungsten carbide residue that is easily crushed for re-use, with ≤50 ppm zinc remaining. While zinc is more effective on cobalt based binding systems, nickel-based bonds can also be recovered using this method and furnace.
