Method for rapidly measuring copper and cobalt in copper-cobalt mixed concentrate

The invention belongs to the field of rock and mineral testing, and particularly relates to a method for rapidly measuring copper and cobalt in copper-cobalt mixed concentrate by using a flame atomicabsorption spectrophotometer. The method comprises the steps of adding hydrochloric acid to a weighed test material and carrying out low-temperature heating on an electric heating plate; then adding nitric acid and perchloric acid; carrying out steaming on the electric heating plate to be nearly dry; taking down a solution for cooling; adding the nitric acid and carrying out blowing and washing byusing a washing bottle; carrying out heating on the electric heating plate until the solution is clear; taking down the solution for cooling and making up the volume; and preparing copper and cobaltcalibration solution series and a test solution of a 2% nitric acid medium, simultaneously carrying out measuring by the atomic absorption spectrophotometer, and calculating a result. According to themethod, only one sample nee
