摘要
云南某锡矿硫精矿中铜品位为0.63%,铋品位为0.08%,具有综合回收的价值,但长期无法得到利用。通过工艺矿物学研究查明了影响铜、铋选矿指标的矿物学因素。研究结果表明,主要的铜矿物为黄铜矿,铋矿物包括自然铋和辉铋矿。黄铜矿的粒度粗但解离度低,需要进一步解离后才可能获得合格的铜精矿;铋矿物的原生粒度极细,是影响铋回收的主要原因。
Copper and bismuth grade of the sulfur concentrate from a tin deposit in Yunnan Province is 0. 63%and 0. 08% respectively. Copper and bismuth,which are worth to recover,cannot to utilized in the past. Process mineralogy study reveals mineralogy factors that influence flotation results. The results show that chalcopyrite is in middle particle size but liberation is low. Hence,grinding is necessary in order to achieve qualified copper concentrate. Fine grain of bismuth minerals is the main reason influencing bismuth recovery.
