Recovery method for recovering tungsten or cobalt from cemented carbide powder |
| abstract |
The present invention provides a novel recovery method for allowing tungsten to be recovered by non-heating oxidation and for recovering tungsten from cemented carbide powder by leaching at ordinary temperature and pressure. Moreover, providing the collection | recovery method which can collect | recover cobalt easily by dissolving cobalt in the leaching solution side. In a recovery method of recovering cobalt or tungsten from cemented carbide powder, (1) a leaching step of leaching cobalt by immersing the cemented carbide powder in an inorganic acid, and (2) leaching cobalt. A solid-liquid separation step for solid-liquid separation into a leachate and a residue; (3) a mechanochemical treatment step for performing mechanochemical treatment after adding potassium permanganate to the residue; and (4) a mechanochemical treatment step after mechanochemical treatment step. And an alkali leaching step of leaching the product after chemical treatment with an alkaline solution. [Selection] Figure 1 |
