These problems are determining recharge area position, water source, uranium source of the groudwater in sandstone; the relation between partial discharge source of the groundwater in sandstone and uranium ore-forming; the relation between mineralizing hydrogeochemistry condition and fixed position uranium deposit or uranium ore-body or uranium mineralizing range; and relation between hydrogeochemistry trackways (such as, uranium, thorium concentrations; Th/U,〓U/〓U,〓Th/〓U, and 〓Th/〓U ratios etc) in the rock and uranium ore-body fixed position and so on.

详细研究的问题有：含铀砂岩地下水补给区及水源、铀源问题；局部排泄源与铀成矿关系问题；成矿水文地球化学条件及其与铀矿床及铀矿体或铀矿化地段定位关系问题；以及岩石中水文地球化学形迹(铀、钍含量、Th/U、〓U/〓U、〓Th/〓U和〓Th/〓U比值等)与铀矿体定位的关系问题等。

In the future, further reducing the size of ore fed into mill and pre-taking out a part of waste rock before feeding ore into mill are the trend of development of ore grinding technology.

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。
