The paper is devoted to the relevant issue of recycling scrap of the strategic WC-Ni alloy used in the production of armor-piercing shells. The recycling of tungsten and nickel carbide eliminates the problem of shortage and high cost of these components. This paper investigates the effect of the concentration of hydrochloric acid and iron (III) chloride in the leaching solution on the extent of nickel leaching from cemented tungsten carbide. It was found that an increase in the concentration of both components leads to an increase in the process rate. It has been shown that the addition of iron (III) chloride to the acid leaching solution leads to a fivefold increase in the process rate. It has been established that the activation energy of the leaching process in a solution of 4.5 mol/L chloride acid is 50.5 kJ/mol. The activation energy of leaching in a solution containing 4.5 mol/L hydrochloric acid and 2 mol/L iron (III) chloride is 17.9 kJ/mol. When switching from an acid leach solution to a solution containing a mixture of acid and iron (III) chloride, the process moves from the kinetic to the diffusion region. To accelerate leaching under conditions of diffusion limitations, it is proposed to increase the efficiency of surface renewal of raw material pieces by selecting the size and rotation frequency of the grinding drum. It has been shown that the dependence of the leaching degree on the drum rotation frequency passes through a maximum. Increasing the diameter of the drum increases the leaching degree. A new method for leaching a WС-Ni composite to obtain high-quality tungsten carbide powder has been proposed. The process intensification is achieved by organizing leaching under self-grinding conditions with continuous mechanical renewal of the surface that is in contact with the leaching solution.
