Latest Patents
Johnson's patent, titled "Extraction of tungsten from spent or scrap catalyst materials," represents a breakthrough in the recovery of valuable materials from waste. The patent details a method where a spent or scrap tungsten-containing, aluminosilicate catalyst material is mixed with a silicate-containing, tungsten-bearing ore concentrate. This mixture is treated with an alkaline solution, such as sodium carbonate, under pressure and at an elevated temperature. This process ensures that at least 2.0% by weight of the total tungsten values in the mixture are derived from the catalyst material, thus facilitating the effective extraction of tungsten while minimizing silica dissolution in the leach liquor.
