尾矿

The area where velocity increases is strengthened with extra material, which further protects against the destructive abrasiveness of the copper mine tailings.

流速加快的部位采用超厚的材料加以强化，而且还进一步保护设备不受具有破坏性研磨能力的铜尾矿的损害。

In recent years, Chinese economy and industry quicklyadvance. Tailings dam rapidly aggrandize along with the demand increase of mine rawmaterials.

随着我国经济的快速发展和工业水平的迅速提高，对矿山原材料产出的需求越来越大，尾矿坝数量也随之增加。

Separation of the sub-quality part of the ore and the barren rock is exercised by the fractionated screening of each size of the ore by application of the lump size X-ray spectral separation and the small-portion X-ray spectral classification with the following purifying operations of the tail products of the main processes for each of the fraction, which are similar to the main processes.

在应用大规模的X射线光谱分离和小部分X射线光谱分类分级筛选不同大小的矿石的基础上，对次级矿石和贫矿石进行净化处理。然后，对各部分主要过程的尾矿进行净化处理，各个小部分的处理方式都类似于主要部分的处理方式。

The invention accomplishes the utilization of industrial castoff of mill run and gangue of bauxite with simple technics and low cost, which is prone to industrialization.

本发明实现了对铝土矿选矿尾矿这一工业废弃物的利用，工艺简单，成本低廉，易于工业化。

The feasibility and effect of using some effective element of the tailing in flotation as the catalyzer for bioleaching were investigated.

探索了利用选矿尾矿中的有效成份作为低品位铜矿细菌浸出催化剂的可能性及浸出效果。

As gold tailings fine grain, and pharmaceutical processing, as well as containing metal ions, an event of high winds, especially in the dry season 3-6, Guade tailings sand rose, dusty, into the villages, fields, orchards, to be against pollution, the pollution resulting from this dispute will be a direct impact on social stability and unity.

由于金矿尾矿粒度细，并含有选矿药剂以及金属离子，一遇大风，特别是干季3—6月份，将尾矿刮得黄砂骤起、尘土飞扬，落入村庄、农田、果园，使其受到污染侵害，由此而产生的污染纠纷将直接影响社会的安定团结。

The burnability of raw materials, which utilized iron-mine tailings instead of iron powder to proportion raw material was better at the same modulus-value. It reduces the sintering temperature of clinker by thirty degrees centigrade. The performance of clinker was better than the one that used iron powder to proportion raw material.

利用南京梅山矿业有限公司铁矿精选后的综合铁尾矿代替铁粉配制水泥生料，在相同率值条件下，综合铁尾矿配制的生料易烧性好，它可降低熟料烧成温度约30℃，烧成的熟料性能优于铁粉配料的。

The ore of arsenopyrite is very easy to float, but hard to inhibit, the experiment creatively forward to the "Select I" in the middling re-election, and then incorporated into the final railings discharge, re-election of concentrate back to roughing of the closed-circuit process. Succeeded in separation the iron of marmites and arsenopyrite the concentrate grade obtained Zn 41.56%, recovery rate is 93.08%, comprehensive collect silver, gallium, indium and other rare metals.

毒砂可浮性很好，易浮难抑，本试验创造性地提出了精选I的中矿再选、再选尾矿并入最终尾矿排放、再选精矿返回粗选的新闭路流程，成功地实现了铁闪锌矿与毒砂的有效分离，获得了锌精矿品位41.56％、回收率93.08％的指标，同时综合回收了银、镓和铟等稀贵金属。

Theoretical calculation values of apparent activation energy and saving energy ef-fect from reaction of clinker formation with raw mix...

得出了尾矿配料和粘土配料的熟料形成的反应表观活化能和尾矿配料节能效果的理论计算值。

And the thin degree of mineral is very thin. If want to achieve the rich purpose to collect the iron through rub the tailing again to separate the silicon and irons from the ore, it is very difficulty and the cost is too expensive.

由于浮选后的精矿品位不高，尾矿产生量大，其铁品位在43%左右，且原矿磨矿细度已经很细，如果想通过尾矿再磨，分离矿石中的硅和铁，达到富集铁的目的，难度很大，且成本不合算。
