摘要
采用矿浆流变性测试与浮选试验,研究了微细粒白钨矿浮选体系中微细粒白钨矿、方解石、石英及其人工混合矿矿浆流变性、浮选行为与调浆过程能量输入之间的关联机制。结果表明,微细粒白钨矿与方解石矿浆表观粘度高、屈服应力大、聚团程度较严重,造成混合矿具有较大的表观粘度与屈服应力。通过搅拌调浆过程能量输入调控,能够显著提升浮选过程选择性。
The interrelationships among the rheological properties,the flotation performance and the energy input were investigated using rheological measurement and flotation tests for the slurry of scheelite,calcite,quartz and their artificial ore in the fine scheelite flotation system.It is demonstrated that fine scheelite and calcite pulps,exhibiting high apparent viscosity and yield stress,can result in complex rheological properties for the artificial ore flotation system.The flotation selectivity could be remarkably improved by adjusting the energy input in the conditioning process.
