摘　　要：本文着重介绍了利用硫酸厂余热蒸汽作为热源,并采用空心桨叶干燥机处理铜精矿中油水的生产工艺,通过含钼物料干燥试验和生产实践表明,干燥后的钼精矿有效地提高了多膛炉的一次出炉合格率,经济环保效益可观。The technology of using the afterheat steam from sulphuric acid plant as heat source and utilizing the dry- er with hollow propeller blades to process the oil and water in the molybdenum concentrates were introduced in this paper. The drying test of molybdenum concentrates and the production practice showed that the dried molybdenum concentrates could improve the qualified rate of products in the multi - hearth roaster and the environmental and e- conomic benefits was also considerable.
