我国作为一个铀矿资源大国，目前已建成数十个铀尾矿库，并已运营了多年，其中堆放了大量的铀尾矿，因此，面临的这一问题尤为严峻。

Study of experimentation, in which the medicament acted on the resistance and occlude action of venomousness and poisonous ingredient of gangue-brick, showed that the medicament on gangue-brick had the effect of pervading and lixiviating the venomousness ingredients.

在制砖扩大试验中，对实验室试验制砖的各项技术指标的最佳条件进行了验证，考查其重现性及误差；对扩试设备运行的连续性、稳定性和可靠性进行了考查；对试验中砖制品出现的技术问题进一步补充、完善，使扩试砖制品质量稳定并达到国家相应建材标准；根据扩试结果进行经济成本估算等，使尾矿制砖技术更趋完善。

The paper present the productive circumstances of recovering bismuthite from the magnetic dressing tailings of wolframite in Tieshanlong tungsten mine, point out the necessity of desulphurization before the floatation of bismuthite , and put forward the attentive matters in the floatation process.

介绍了铁山垅钨矿从黑钨磁选尾矿中回收泡铋矿的生产情况，指出了浮选泡铋矿之前脱净硫化矿物的必要性，并提出了生产操作中应注意的事项。

The degradation law for potassium ethyl xanthate is studied for itself and tailings reservoir separately in the condition of visible light and ultraviolet radiation.

本文研究了在可见光和紫外光条件下选矿药剂乙基黄原酸钾自身以及在模拟的尾矿库环境中的降解规律，分析了乙基黄原酸钾在不同条件下的降解趋势，以及尾矿和不同的光存在条件下对乙基黄原酸钾降解的影响。

In the tests, the nonionic type polyacrylamide, the anion type polyacrylamide and the zwitterion type polyacrylamide, and the compounding of the poly-aluminum chloride/PHP and the calcium chloride (CaCl2)/NPAM were used as flocculation agents.

选择聚合氯化铝/阴离子型聚丙烯酰胺、氯化钙（CaCl2）/非离子型聚丙烯酰胺组合与NPAM、PHP、两性离子型聚丙烯酰胺作为絮凝剂，在对道清选煤厂水采筛下原生煤泥和浮选尾矿的煤泥水进行组合药剂絮凝实验的基础上，考察了pH对煤泥水絮凝沉降的影响。

The results show that REEs oxide have little effect on the decomposition of carbonate and they improve the sinterability of the raw meal;they also promote the formation of alite and growth of clinker minerals,and have beneficial effect on the uniformity of crystal size and well-distributed minerals. But some REEs result in the corrosion of alite when they are excessive,which may influence the hydration reactivity of alite.When clinker is well sintered, REEs oxide and its tailing improve the strength of cement clinker, and have little effect on setting time of cement.

研究结果表明，稀土氧化物对碳酸盐的分解影响不大，对生料的易烧性有改善作用；稀土氧化物能促进熟料中A矿的形成和矿物的发育，有利于熟料中矿物结晶尺寸和分布均匀，但部分稀土在掺量过量时可能造成矿物的熔蚀，影响矿物的水化活性；在煅烧良好的条件下，稀土氧化物和尾矿对熟料强度有增进作用，对水泥凝结时间影响较小。
