在查明南北露天矿物组成、赋存状态等的基础上,针对南露天钼矿石钼品位低、石英含量高、辉钼矿粒度细等与北露天钼矿石性质有较大差异的特点,经过认真分析和详细的试验研究,认为选厂目前的一段再磨细度-400目85%～90%的磨浮流程不太适合南露天钼矿石,所获钼精矿品位和回收率均偏低,要取得较高品位和较高回收率的钼精矿,两段再磨浮选流程较为合理。
On the basis of ascertaining the composition and occurrence state of opencast minerals in the north and south, according to the characteristics of low molybdenum grade, high quartz content, fine grained molybdenite size and the properties of northern open-cast molybdenum ore, Analysis and detailed experimental research, it is considered that the current grinding process of 85% -90% of 400 millimeters is not suitable for the southern open-pit molybdenum ore. The grade and recovery of molybdenum concentrate obtained are both low, To obtain a higher grade and higher recovery of molybdenum concentrate, two resurfacing flotation process is more reasonable.
