研究了在硝酸“催化”常氧压下浸出闪锌矿时,元素硫的生成率随时间、温度、硝酸根浓度、酸度、矿石粒度等因素的变化。结果表明,元素硫的生成率仅与温度有关,当温度小于343K时,闪锌矿被溶解,其中所有的硫均转化为元素硫,而当温度大于343K时;元素硫生成率仅为80％,其余转化为硫酸根。文中还研究了浸出中所生成的元素硫的形貌。 The change of elemental sulfur production rate with time, temperature, nitrate concentration, acidity, ore size and other factors was studied when leaching sphalerite under “normal” atmospheric pressure of nitric acid. The results show that the formation rate of elemental sulfur is only related to temperature. When the temperature is less than 343K, the sphalerite is dissolved and all the sulfur is converted to elemental sulfur. When the temperature is higher than 343K, the elemental sulfur formation rate is only 80% , The rest is converted to sulfate. The article also studied the leaching of the elemental sulfur morphology.
