In the pH range of 6~12, the results of the flotation tests indicate that the performance of the new combined cationic collector (CS3:CS1=3) and (CS3:CS2=2) is similar, and they are effective collectors for reverse flotation of the iron ores. The combined cationic collectors exhibited the same collectability as dodecylamine, but better selectivity than dodecylamine. By using the combined collector, the dosage of the collector decreased from 1 10-4mol/L to 1 x 10-5mol/L .

单矿物可浮性试验结果表明，在pH=6～12的范围内，新型组合药剂CS_3：CS_1=3和CS_3：CS_2=2具有相近的药剂性能，在其捕收能力与十二胺相当的前提下，不但选择性较十二胺好，而且还能显著提高药剂的协同效应，使药量从单用时的1×10~(-4)4mol／L降至1×10~(-5)mol／L，是铁矿石反浮选的高效捕收剂。

The Jiashengpan lead-zinc-sulfur deposit, located in Langshan-Zhaertaishan mineralization belt in the western part of northern margin of North China Platform, rich in Mesoproterozoic Zhaertaishan Group, is obviously stratabound and controlled by synchronous fault. The ore bodies are mainly composed of layered, conglomeratic and disseminated ores.

甲生盘铅锌硫矿床位于华北陆块北缘西段狼山-渣尔泰山成矿带，赋存于中元古代渣尔泰山群地层中，具有明显的层控特征并受同生断裂影响，区内矿石层纹状、角砾状和浸染状构造发育。

The study of microwave-aided leaching deepens our understanding of desiliconization mechanism in leaching and presents a valuable reference for research of microwave hydrometallurgy and sulfuric acid leaching of high silica zinc oxide ores.

微波辅助浸出工艺的研究，加深了矿石浸出过程除硅机理的认识，为氧化锌矿的硫酸浸出工艺和微波湿法冶金研究提供了很有价值的参考。

The effects of temperature, dialogite-to-sulfuric acid ratio, and solid-to-liquid ratio on leaching of dialogite by sulfuric acid were researched in the leaching experiment of ores from Hubei.

通过对湖北矿的浸取试验研究，讨论了温度、矿酸比、固液比对菱锰矿硫酸浸取的影响，优化了浸取条件，并确定温度对浸取的影响最为显著，使浸取率可以达到99。

虽然硅藻土属于我国资源的优势矿种，但目前的开发水平还不高，除少数产品达到国际水平外，大多数产品的质量还待提高，可见，对硅藻土的进一步研究具有重要的理论意义和实用价值。

As for sulfur isotopic composition, the general feature of two types deposits is a single peak distribution. All δ〓s values of the ores are near zero. The difference of different deposits lies in that the δ〓s values (1. 8-5. 2‰) of LDT are of small positive value and are similar to that of the metamorphic rocks and dioritic porphyrites in the region while the δ〓s values of SDT are always near zero. Features above suggest that two types of deposits have closely genetic relationship to metamorphic and magmatic rocks.

硫同位素组成上，两类金矿床共同的特征是均具有明显的单峰塔式效应，且δ〓S值均位于0值附近不大的变化范围内；不同的是，近程式金矿的δ〓S平均值均接近于0，与该类金矿具密切成因联系的岩体的δ〓S值也接近于0值，而远程式金矿的δ〓S平均值均为小的正值，变化范围为1.8～5.2‰，区内太古代变质岩及矿区内闪长玢岩脉的全岩δ〓S值位于这一区间内，反映了远程式金矿床其成矿物质不仅来源于重熔岩浆，同时还可能部分来源于变质岩围岩。
