The analysis process of silver in copper anode slime includes adding HNO3 into sample and heating to decompose, adding HCl, heating to evaporate, cooling, adding water, heating to boil, cooling, filtering with quantitative filter paper, washing container and deposit, setting the deposit together with the filter paper into the container, adding H2SO4, carbonizing, adding HNO3 until the solution become colorless, heating to smoke with dense white smoke, cooling, diluting with water, adding ferric ammonium sulfate as indicator, and titrating with standard potassium thiocyanate solution to light red as the terminal. The method is simple, fast, accurate, and suitable for the analysis of silver in copper anode slime.
