The structure water is dehydrated completely as the temperature is over 1,100 K, the characteristic peak (3,580 cm-1) of the structure water disappears completely, the characteristic peak related to Si-Onb stretching vibration becomes 855 cm-1, which shows that primary Q1 of the hemimorphite is returned to Q0 (i.e [SiO4] ), and which means that the hemimorphite is completely transformed to willemite.

当升温达1 100 K以上，结构水的特征谱峰(3 580 cm-1)消失，与Si-Onb对称伸缩振动对应的特征拉曼谱峰变为855 cm-1，这标志着异极矿原有的Q1结构已完全转变为硅锌矿的Q0结构([SiO4]结构)，也就是说异极矿已完成向硅锌矿的转变。关键词：异极矿；原位拉曼光谱；测试；相变；高温

Results showed that enzyme activities were significantly different, urease activity: park＞school＞residence＞industry＞road; phosphatase activity: park＞industry＞school＞residence＞road; invertase activity: residence＞park＞industry＞road＞school; But the dynamic patterns of SOC mineralization from different functional areas were similarly, the rate of SOC mineralization decreased quickly at the beginning, and then decreased slowly during the middle incubation time, and keep relatively constant during the later incubation time, and fitted to logarithmic equation with incubation time.

结果表明：不同功能区土壤酶活性差异显著，脲酶：公园＞学校＞居民区＞工厂＞道路；磷酸酶：公园＞工厂＞校园＞居民区＞道路；转化酶：居民区＞公园＞工厂＞道路＞学校；但不同功能区土壤有机碳矿化过程动态表现出相同规律，在培养前期有机碳矿化速率迅速下降，培养中期缓慢下降，培养后期保持相对稳定的趋势，有机碳矿化与培养时间符合对数关系；整个培养期内，土壤有机碳矿化速率及累计矿化量公园＞工厂＞道路＞学校＞居民区。

因此我们开展了真空下还原剂直接还原高铁闪锌矿工艺的热力学分析和实验研究，该方法实现了高铁闪锌矿的直接熔炼处理，具有能单独处理铁闪锌矿、流程短、无污染、金属回收率高、综合利用好等优点，且针对我国丰富的难处理锌资源一高铁闪锌矿，转变铁闪锌矿资源优势为经济优势，应用前景广阔。

Process of flotation of acture ore is the following: firstly, adding Na_2CO_3, ZnSO_4, CSU-1 to the pulp while grinding, and thus in this condition of low Eh, marmatite is inhibited; Secondly, adding CSU-1 to the pulp out of grinding machine, then amesonite and iron sulfur mineral can be flotated using diethyldithiocarbamate as collector; High quality lead and antimony concentrate can be got by adding CSU-1 and calcareousness; Lastly, marmatite is flotated by adding calcareousness, CuSO_4, xanthe, and D-250 to get zinc concentrate.

小型试验研究表明，首先在脱硫粗选作业只加入适量的Na_2CO_3、ZnSOO_4、和CSU-1至磨矿机，利用磨矿机的研磨和磨机中的低电位环境，使铁闪锌矿受到抑制，而最容易浮的脆硫锑铅矿和黄铁矿、磁黄铁矿等硫化矿物则依然具有可浮性；在磨机出来的矿浆中分别加入CSU-1进一步抑制易浮的铁闪锌矿，然后加入乙硫氮将脆硫锑铅矿和硫化铁矿快速浮净，加入石灰和CSU-1，浮选分离出高质量的铅锑精矿；接着添加石灰、CuSO_4、黄药及2~#油选别铁闪锌矿。

The industrial test for Lanping lead-zinc oxidation mine was carried out in this paper.The results showed that too low recovery rate of zinc was not induced by the flotation process of oxidation zinc mine,and the key point of solving the problem lied in how to reduce the produce rate of gangues and how to increase the recovery rate of the metals in gangues.The economic benefit of this process was also evaluated,the result showed that the economic benefit was obvious when the ores of Jiaya Mountain were trea...

对兰坪铅锌矿氧化矿进行了500t/d的工业试验研究，结果表明，氧化锌回收率较低的原因并非氧化锌浮选工艺的问题，如何降低矿泥的产率和能否回收矿泥中的金属将是解决兰坪难选氧化铅锌矿的关键所在，同时也对该工艺进行了经济效益评估，采用现行工艺处理架崖山工业矿具有一定的经济效益，在进一步完善现有工艺的基础上，具有一定的应用前景。

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.
