摘　　要：针对传统轴流型调浆搅拌槽剪切能力不足,西藏甲玛某选矿厂采用了强化调浆技术及设备(调浆改质机),使矿浆中矿物颗粒与浮选药剂充分接触并混合。实验室对比实验可知,适当地提高浮选前搅拌调浆的转速及适当地延长浮选前搅拌调浆的时间,可在一定范围内提高浮选回收率。生产指标对比表明,在两个系列处理相同矿石,同时保持相同浓度、细度、药剂制度及流程的情况下,使用该设备的系列Cu、Au、Ag、Mo回收率比不使用的系列分别高0.53%、3.92%、1.04%及6.25%。该设备强化了叶轮剪切作用,增加了药剂与矿物颗粒的碰撞机会,充分发挥了药剂效果,在一定程度上提高了选矿指标。In order to solve the shortage of shear capacity of the conventional axial-flow agitator,a concentrator of Jiama in Tibet has adopted a new type of high-intensity mixing technology and equipment.The mineral particles in the pulp and flotation agents can be fully contacted and mixed.The laboratory comparison test shows that appropriately increasing the speed of stirring and adjusting slurry before flotation and appropriately extending the time of stirring and adjusting slurry before flotation can increase the flotation recovery rate within a certain range.The comparison of production indexes shows that the recovery rates of Cu,Au,Ag and Mo with the equipment are 0.53%,3.92%,1.04%and 6.25%higher than those without the equipment when the two series treat the same ore with the same concentration,fineness,reagents system and process.The equipment strengthens the shearing effect of impeller,increases the chance of collision between reagents and mineral particles,gives full play to the effect of reagents and improves the beneficiation index.
