【摘要】：河南某钼矿入选品位逐渐下降,使用单一的煤油作为捕收剂已经很难适应矿石的变化,为优化选厂粗选作业药剂制度,研究采用不同的稠环芳烃与煤油配制成复合烃油,作为捕收剂对该钼矿进行了试验。结果表明,三种复合烃油都不同程度地提高了钼的回收率,其中"煤油+稠环芳烃A"作为捕收剂的选别指标最佳。在煤油与稠环芳烃A以95∶5的质量比配制成的复合烃油作为捕收剂,总用量为170g/t的条件下,可获得品位为9.23%,回收率为85.53%的钼粗精矿。与以煤油作捕收剂相比,回收率提高了3.03%,此复合烃油对回水有较好的适应性,能够大幅度地改善选别指标。
[Abstract]:The grade of a molybdenum ore in Henan Province is declining gradually, so it is difficult to adapt to the change of ore by using a single kerosene as collector. In order to optimize the reagent system of rough separation in the separation plant, different dense aromatic hydrocarbons and kerosene are used to prepare the compound hydrocarbon oil. The molybdenum ore was tested as a collector. The results showed that the recovery rate of molybdenum was improved to some extent by the three kinds of complex hydrocarbon oils, among which "kerosene dense cyclic aromatic hydrocarbon A" was the best collector. The crude molybdenum concentrate with a grade of 9.23 and a recovery rate of 85.53% can be obtained under the conditions that the kerosene and the dense cyclic aromatic hydrocarbon A are compound hydrocarbon oil prepared by 95:5 mass ratio as the collector and the total dosage of the oil is 170g/t. The crude molybdenum concentrate with a grade of 9.23% and a recovery rate of 85.53% can be obtained. Compared with kerosene as collector, the recovery rate is increased by 3.03.The compound hydrocarbon oil has better adaptability to backwater and can greatly improve the separation index.
