【摘要】 以硬锌渣为铟原料,以工业盐酸为浸出剂,在常规浸出装置中研究了反应温度、反应时间、盐酸初浓度、颗粒粒度和液固比等因素对铟浸出率的影响,得到了湿法浸铟的工艺优化条件。将硬锌渣粉碎至粒度为-40+80目、用9.9 mol/L的工业盐酸浸出时,在液固比为4.0、反应温度为80℃、反应时间为80 min的反应条件下,铟浸出率可达到90%以上。更多还原

【Abstract】 Study was made on the effect of the temperature and time of reaction, initial concentration of hydrochloric acid, particle size and liquid - solid ratio on indium leaching rate in the indium leaching from hard - zinc slag with industrial hydrochloric acid as leachant and by conventional leaching installation, and the optimum conditions for indium leaching were determined. The indium leaching rate of over 90% was achieved at -40+80 mesh crushed particle size of hard -zinc slag, industrial hydrochloric acid concentration of 9.9 mol/L, liquid -solid ratio of 4.0, reaction temperature of 80% and reaction time of 80 min.更多还原
