This is an essay in the field of metallurgical engineering. In the hydro-zinc smelting system, the large amount of chloride ions seriously restricts the normal production. In this essay, a new type of X agent is used for the dechlorination test. Neutral leaching solution was used as the research object to explore the influence of X agent addition, neutral leaching solution temperature, pH value, reaction time, and impurities F− and Mg2+ on the chlorine removal rate. The test results show that when the dosage of X agent is 8 times, the reaction time is 60 min, the reaction temperature is 60 ℃, and the pH value is less than 5.5, X agent has the relatively highest rate of chlorine removal, about 85%; among them, F− no obvious effect on the chlorine removal rate; when the Mg2+ concentration exceeds 16 g/L, the chlorine removal rate of the X agent drops slightly. |
