mine tailings meaning in Chinese
尾矿
Examples
- Filtration effect of the classified fankou pb zn mine tailings using homemade ceramic filter
国产陶瓷过滤机过滤分级尾砂试验研究 - Soil fertility and heavy metal contamination in abandoned regions of different mine tailings in yunnan province
云南不同矿区废弃地土壤肥力与重金属污染评价 - In order to choose the plants that were hypertolerant to heavy metals and for the case of phytoremediation of soils that were polluted by heavy metals , the research was carried out by the methods of soil - planting and sand - planting in green - house . the study includes selecting the hypertolerant plants from 36 dominant species found in the vicinity of a pb / zn mine tailings pond , observing the ecophysiological response of the hyperaccumulators , improving - impact of hyperaccumulators on biosolds and examining the effect of nutrient elements ( n p k ) on the lead uptake
为选择和筛选富集重金属或对重金属具有耐性的植物,以达到利用植物修复重金属污染土壤的目的,本研究通过温室砂培和土培的方法,对生长于铅锌尾矿区的36种植物进行了筛选,研究了富集植物品种对重金属pb的生理生态效应、对重金属pb的吸收和耐性以及对污泥的响应,并探讨了土壤中的营养元素n 、 p 、 k对植物吸收pb的影响,为植物修复工作提供理论依据。 - An iron - containing material with an iron grade of over 20 % can be recovered from magnetic separation tailings of liuling iron mine by gravity method . this material can be used instead of partial clayey material to produce portland cement so as to reduce the mine tailings discharge amount to 43 . 52 % , to raise the iron recovery from 70 . 89 % to 84 . 62 % and to reduce the iron ore powder consumption in raw cement mixture and the energy consumption of raw material grinding
用重选法从刘岭铁矿磁选尾矿中回收铁矿物,可获得铁品位大于20 %的含铁物料,用此物料代替部分粘土质原料生产硅酸盐水泥,使矿山尾矿排放量减少至43 . 52 % ,铁的回收率由70 . 89 %提高到84 . 62 % ,并且减少了水泥生料配料中铁矿粉的用量,降低了生料粉磨能耗。
