摘要：

The article analyses the process of copper alloy refining by means of chemical bonding; arsenic dissolved in liquid copper reacts with pieces of titanium and a new phase TiAs is being formed. Numerical simulation of the kinetics of this process was performed. It was assumed, that the process is diffusion controlled. Calculations consisted in simultaneous solution of a non-stationary diffusion of Ti and As at variable concentration field of both reagents, variable position of the reaction zone and variable radius of the spherical particle of titanium. The rate of the process and the time of arsenic removal for different size of titanium particles were calculated.
