铁闪锌矿

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

Data of major andminor elements in magnetite, cassiterite, galena and sphalerite from oredeposits within this ore belt suggest that these ore deposits are of skarn,hydrothermal, porphyry and greisen types related to Yanshanian magmaticactivity and that iron in ores came from regional Permian marine interme-diate-basic volcanic rocks whereas partial lead and zinc from Permian geo-synclinic sediments.

矿带中各矿床的磁铁矿、锡石、方铅矿、闪锌矿的主元素和微量元素数据表明，这些矿床是属与燕山期岩浆活动有关的矽卡岩型、热液型、斑岩型和云英岩型矿床；其成矿金属组分中的铁来源于区域晚古生代海相中-基性火山岩，部分铅锌来源于区域二叠纪地槽沉积物。

The simulation of Fe doped sphalerite (110) surface and Cu adsorption on the sphalerite surface were performed by using plane wave-pseudopotential approach based on density-functional theory.

摘 要：采用基于密度泛函理论的平面波赝势法对含铁杂质闪锌矿(110)表面电子结构及铜在闪锌矿表面的吸附进行模拟。

Through thermodynamic calculation and electrochemical analysis of multiple redox reactions on the minerals of galena, sphalerite and pyrite in different system, it could be found that pulp chemical environment in which hydrophobe of collectorless flotation produced was beneficial to reduce collector dosage in existing flotation system; electrochemical analysis on sphalerite had been engaged; and pulp chemical environment of OPF for lead-zinc-iron sulfide minerals and relevant selective measure for collector and modifer were established.

通过对方铅矿、闪锌矿、黄铁矿在水体系、调整剂体系、捕收剂体系中由局部电池造成的多种氧化—还原反应的热力学分析和电化学测试，补充和完善了铅锌铁硫化矿浮选电化学理论。提出了矿物表面无捕收剂疏水体生成的矿浆化学环境有利于降低现有浮选体系中捕收剂用量的观点；成功地进行了闪锌矿的电

The marmatite has sulphur-induced flotability at neutral and weakly alkaline pulp.

在中性和弱碱性条件下，铁闪锌矿具有硫诱导无捕收剂浮选。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
