求翻译：选矿分选作业中有用目标组分含量最低的、在当前的技术经济条件下，不宜再进一步分选的粉状物，称尾矿。粒径一般≤0.074mm[3]，颗粒细小、质量轻，放置干燥地区无覆盖下，遇风极易被风卷起，形成砂尘甚至形成砂尘暴，是大气污染中重要的污染源之一。矿区多位于郊区、农村，其扬起的尾矿将影响农田果树花期的授粉，造成果实的大量减产，并影响附近的动植物生长。位于城市郊区的，严重的影响城市的空气质量，造成大范围的大气污染，对人民的生活带来严重影响。尾矿中有毒、有害元素，随粉尘颗粒一起漂浮，加重了其危害程度。是什么意思？

In dressing separation process useful goal component content lowest, under current technical current economic condition, is not suitable powdery which further separates again, calls the debris.Particle size general ≤0.074mm[3], the pellet tiny, the quality is light, the laying aside dry area does no

Beneficiation separation minimum useful target component in the job content, in the current technical and economic conditions, should not be further sorting of the powder, called tailings. Diameter ≤ 0.074mm[3], small particles, light weight, place dry areas under non-coverage, the case of wind too
