If we ask iron ore powder content of the final product particle size less than 100% of negative 80μm, its large particle proportion of mineral particles is relatively small, high frequency sieve sieve wear and tear is not serious under the premise of high-frequency vibrations can be used sieve for grading,Screen carried out under the magnetic separation of ore; sieve of coarse ore, return to re-grinding mill.

如果要求铁精矿粉最终产品粒度负80μm含量低于100%时，其大颗粒的矿粒所占比例比较少，对高频筛的筛片磨损不严重的前提下，可采用高频震动筛进行分级，筛下的中矿进行磁选；筛上的粗矿，回到磨机重磨。

Since the ore-bearing rock is located in the area of the geological background, the model parameters varies from here to there due to the topography, soil and vegetation. The remotely sensed data recorded the various information of the ore-forming procedure at one time, so the ore-bearing rock information of the characteristic of weakness, not easy to detect, surface weathering and environmental interfering make it more difficult to unveiling.

但是，矿产遥感信息的模式定量化异常困难，这是因为遥感信息一次性记录地质历史上各种地质过程和各种成矿作用留下的诸多标志、形迹，因此，成矿作用过程中所产生的异常信息具有信息弱，隐蔽性强、地表贫化和环境因素干扰等特点，造成反演的多样性和复杂性。

Metal miners have: gold and silver ore, lead-zinc, iron ore, copper, molybdenum mine; non-metallic mine to have asbestos, marble, limestone, granite, potash feldspar ore, quartz quarry, sepiolite mining, lignite and so on.

金属矿主要有：金银矿、铅锌矿、铁矿、铜矿、钼矿；非金属矿主要有石棉、大理石、石灰岩、花岗岩、钾长石矿、石英石矿、海泡石矿、褐煤等。

The upcoming three iron ore prices negotiations, many steelworks in state. 19 have announced came news that Brazil iron ore mining contractor CVRD company has proposed for China's steelmakers in the third quarter of iron ore prices is in the second quarter, to improve 23%, and $1.6 per ton in wisco have received the proposal.

即将来到的三季度铁矿石价格谈判，令不少钢厂处于紧张的状态。19日有外电传出消息，巴西铁矿石开采商淡水河谷公司已提议将第三季度面向中国钢铁厂商的铁矿石价格较第二季度提高23%，至每吨160美元，而武钢已经接到该项提议。

The ore-control structure can be divided into two types which are transtension fracture and transpression fracture. The former controls quartz vein ore, and the latter controls altered rock ore.

控矿构造可分为两种类型，既压扭性和张扭性，前者控制着蚀变岩型矿体分布，后者则控制着含金石英脉型矿体分布。

Acording to the results for the analysis of component and structure of titanic iron ore with X-ray diffractometer and the fact in that titanic iron ore is prossessed of a dielectric property capable to absorb evidently microwave, a household microwave oven with power of 800W is applied to the decomposition of titanic iron ore sample under atmospheric pressure. It is shows that the sample with size of below 0.125nm can completely decomposed with phosphoric acid or mixture of phosphoric acid and sulfuric at about 160℃(corresponding to mid-low fire gear in microwave oven).

本实验根据X-射线衍射仪分析钛铁矿组成和结构的结果，利用钛铁矿显著吸收微波的介电特性，使用改装后的800W家用微波炉，在常压下选择中低火加热温度（160℃左右），分别用磷酸和磷硫混酸在微波辐照下消解粒度小于0.125mm的矿样，可快速将矿样消解完全。

Except the sulfate ore containing iron affect the granite tile , most of ore contain iron may exist in granite tile , silicic acid iron ore spread widest in area and quantity.

一、含铁矿物对花岗石石材的影响除了含铁硫酸盐矿物外，大部分的含铁矿物都有可能存在花岗石中，属硅酸铁矿物的数量及分布最广，其次是氧化铁或硫化铁矿物。

Figure 2 shows the jigging concentrate relations between content and ore feeding volume, when the diaphragm jig and the sawtooth pulsation jig are provided with different ore volume. Figure 3 shows the jigging concentrate relations between the sulphur recovery rate and ore feeding volume. As the test result shows, when the tailing content reaches approximately 7%, the diaphragm jig has 1.00 t / h · m2 feeding volume, which is also the maximum sorting efficiency in the test. As such, the sawtooth pulsation jig could choose 1.2 t / h · m2 feeding volume. As the test contrast of two groups shows, the sawtooth pulsation jigging concentrate contains higher-grade sulphur than the diaphragm jigging concentrate does.

图2为隔膜跳汰机及锯齿波跳汰机在不同给矿量的情况下，跳汰精矿品位与给矿量的关系，图3为跳汰机精矿硫回收率与给矿量的关系，试验结果表明，在尾矿品位接近7%，隔膜跳汰机给矿量为1.00 t/h·m2指标是隔膜跳汰机给矿量试验中选别效率最高的点，同理选择锯齿波给矿量为1.2 t/h·m2，将两组试验数据比较可以看出，锯齿波跳汰精矿含硫品位高于隔膜跳汰精矿含硫品位。
