内容記述 |
Wasted tungsten scraps are important resources for recycling, however, the mechanical recycle process of tungsten has a difficulty for recycling due to its mechanical strength. Underwater explosion fracturing technique was designed for solving this problem. The kinetics for alkaline leaching of roasted tungsten alloy scraps with different size distribution prepared by two ways of crushing technique has been investigated to evaluate the effect of the underwater explosion-crushing. The merit of this technique for fracturing of waste tungsten alloy scraps can be understood by estimating of those leaching tendencies. The present work aims at the evaluation of the explosion-crushing method for efficiency of alkaline leaching from a kinetic point of view. Alkaline leaching was carried out with 10% NaOH solution in the range of 293-353K at various times. The leaching of roasted tungsten carbide scraps by NaOH was strongly dependent on temperature and leaching time, and underwater explosion accelerated the leaching ratio. The leaching mechanism was turned out to reaction controlled, and activation energy of alkaline leaching was 60-64kJ/mol. |
