尾矿

The tailings lenticle which is a key factor reflecting the sedimentation state of tailings dam, has great influence on the state of saturation line.

透镜体是反映尾矿堆积坝沉积状况的一个关键指标，它影响着浸润线状态。

A lot of hematite and martite lean intergrowth is existed in magnetic concentration tails in concentration mill of Laiwu mine Co ,Ltd For recovering these iron mineral the medium intensity magnete separator is used,and the comprehensive metal recovery factor is increased by an average 1 17%,the grade of tails is decreased by 0 5%~1 0%,the profit is up to 0 77 million yuan

莱矿选矿厂磁选尾矿中含有大量赤铁矿、假象赤铁矿贫连生体，为回收这部分铁矿物，采用了中磁场分选设备，使综合金属回收率平均提高 1。

The karst landform tailings dam disaster appraisal and the safe monitor are important for reducing the risk and the accident. The most prominent factors of influencing the stability of Karst landform in some tailing dams are NW-Trending and NE-Trending Structure's "tabular pattern", bad rock mass globality, highly-jointed, karst, miarolitic, the earth's surface -underground "ladders" fluent movement pattern; the effect of the flood and the earthquake.

Firstly it plays the fine separation role and maintains the separation selectivity, secondly the role of countercurrent-collision mineralization and separation and prerecovering the material with good floatability (the gangue of column flotation as middlings will undergo further separation and recovering).

它首先要发挥精选作用并确保整个设备的分选选择性；然后才是逆流碰撞矿化与分选，预先回收可浮性好的物料（其尾矿还要进一步分选回收）。

Article 30 While mining major minerals, a mining enterprise shall, in accordance with a unified plan, carry out comprehensive mining and utilization of paragenetic and associated minerals that are of industrial value, so as to avoid waste.

第三十条在开采主要矿产的同时，对具有工业价值的共生和伴生矿产应当统一规划，综合开采，综合利用，防止浪费；对暂时不能综合开采或者必须同时采出而暂时还不能综合利用的矿产以及含有有用组分的尾矿，应当采取有效的保护措施，防止损失破坏。

The saturation line monitoring, which is done by manual usually with piezometric tube, is the main investigation item in tailings dam.

浸润线是尾矿坝的主要监测项目，一般采用测压管进行人工监测。
