When copper concentrate is to be produced through ore floatation for sepanting copper minerals and arsenic minerals by using an oxidizer and a sulfur oxoacid, the present invention reduces arsenic in the copper concentrate by using a simple method. According to the present invention, when copper concentrate is to be produced through ore floatation using arsenic-containing copper ore as a material, a sulfur oxoacid and hydrogen peroxide serving as an oxidizer are used in combination as additive chemical agents in the stated order
