%X Reaction between Cu_2S and Cu_2O was investigated at 1150 to 1250℃.The reaction rate in-creases with the increase of surface area of Cu_2O grains and depends unobviously on temper-ature.At the suggestion of controlling step of reaction rate being oxygen diffusion through theliquid layer along reaction boundaries,two final kinetical equations would be made as follows:x=6.69×10~(-2)At for 0<α<0.74 and ln(l-α)=-A(9.83×10~(-2)t+1.76)for 0.74<α<1,whereα is SO_2 evolved in time t and A is surface area of Cu_2O particles.
