Abstract: A method for analyzing debris bed formation based on a multi-resolution multiphase particle algorithm, which uses the least-squares moving particle semi-implicit method with second-order computational accuracy and improves surface tension model and free surface particle identification model. The method also utilizes a particle-based gas-liquid phase transition model and a particle-based liquid-solid phase transition model with multi-resolution features, such that the coolant vaporization and melt solidification processes during the falling process of the melt can be calculated. Moreover, a solid-solid collision model is coupled to calculate the collision and debris bed deformation during the falling process of the debris particles. In this way, the momentum exchange, energy transfer and phase transition between different phases are taken into account, and the computational instability caused by the large physical difference between phases is mitigated.

Abstract: Provided is a recovery method for valuable metals in copper anode slime. By using the recovery method of the disclosure, selenium, copper, tellurium, arsenic, lead, bismuth, and precious metals gold and silver in the copper anode slime are recovered. The method adopts two-step vacuum carbothermal reduction to replace reduction smelting of anode slime and stepwise blowing of noble lead in the traditional pyrometallurgy, and avoids the emission of arsenic-containing soot in the traditional process. The recovered gold-rich residue contains almost no base metals such as lead, bismuth, antimony, and arsenic. After subjecting the gold-rich residue to leaching gold by chlorination and reduction, a gold powder could be obtained therefrom with a lower content of base metals than traditional processes. Therefore, the method greatly reduces the amount of produced slag, shortens the production cycle, and reduces the loss of precious metals in the slag.
