是当前极少数持有国家准许生产氰化亚钾贵金属化工产品证书的专业生产企业。2005年上半年，公司进行了全面整合，聘请了贵金属精细化工专家，加大投资规模，形成了年产值近5亿的生产能力。

He went behind the counter and got a half ounce of prussic acid.

说着，他走到柜台后面，拿出半盎司氰化氢。

Mark did too, for he knew that a single drop of pure prussic acid inside the eye would kill Old Man Fellows almost as quick as lightning.

马克也笑了--因为他明白，只要费罗斯在眼睛里滴上一滴氰化氢，倾刻之间他就会被送入地狱。

Only then did I learn that the Belgian had inhaled a solution of gold cyanide-----which he shared with his dog-----after seeing All Quiet on the Western Front, the picture by Lewis Milestone based on the novel by Erich Maria Remarque.

到那时我才知道，比利时人看了Lewis Milestone根据雷马克的《西线无战事》改编的电影后，和他的狗一起吸入了氰化金钾的溶液。公众的直觉即使在它们听起来不可信时，到也往往包含了点儿真相。

Study on Improvement of Recovery of Gold and Silver from the Copper Dross Smelting in Reverberatory Furnace;2. After that, the copper in leach liquor can be extracted with the ternary extractant mainly containing P204, and the gold and silver in leach residue can be recovered by a process of cyanidation-replacement of Z.

为避免硫酸烧渣对环境的污染，以硫酸烧渣为原料，通过添加活性还原剂，用废硫酸直接还原浸出铁并制铁黄，而后用以P2 0 4为主体的三元萃取剂萃取回收浸液中的铜，用全泥氰化和锌粉置换工艺从浸渣中提取金银，较经济有效地回收利用了烧渣中的有价金属，铁、铜和金的回收率分别达到了 93。

For efficient utilization of phosphorus—rich rhodochrosite and complicated sulfides, we have carried out some studies on enrichment of manganese, dephosphorization and bio-catalytical oxidation of sulfides supported by NSFC (No. 59374150, 59774010), the main contents include: properties of Huayuan Manganese ore; microorganisms preparation of dealing with manganese ore; physiological and biochemical properties of microbes used; the mechanism of microbes function to manganese ore; the separation, tameness of Thiobacillus ferrooxidans and its nutriment; bio—catalytical oxidation mechanism of sulfides; extraction of gold by bio—catalytical oxidation—cyanidation.

为解决我国储量丰富的高磷贫碳酸锰矿石和复杂硫化矿有效利用中存在的问题，我们在国家自然科学基金委员会的资助下（No.59374150，No.59774010），以花垣锰矿石和黄铜矿、黄铁矿等为研究对象，进行了高磷贫碳酸锰矿石的微生物富锰降磷和生物催化氧化硫化矿等的研讨工作，内容包括：花垣锰矿石的性质研究；富锰降磷微生物的筛选；试验用微生物的生理生化特性及富锰降磷机理探讨；催化氧化硫化矿细菌的分离、驯化及营养条件确定；生物催化氧化硫化矿的机制；金的生物催化氧化—氰化提取。

In this paper, the methods of determining free sodium cyanide in cyanidc solution of gold ore by colorimetric comparison are studied, this Laying a foundation for the development of automatic analytical instrument of sodium cyanide at home.

本文研究了用比色法测定金矿氰化液中游离氰化钠的方法，为国内研制氰化钠自动分析仪打下基础。

The elution results showed that there would be a definite effect after the fiber was treated by sodium cyanide after elution by sulphuric acid and ammonia, then with sodium nitrate.

铁的解吸探索实验发现，用第一步硫酸解吸回收氰化氢的氢氧化钠溶液处理第二步氨水解吸后的纤维，然后用硝酸钠解吸，有一定的效果。

When determine free sodium cyanide in cyanide solution, a positive deviation presents markedly due to dissociation of part complex ions of zinc and copper.

银量法测氰化液中游离氰化钠时铜锌络离子的部分解离造成显著的正偏差。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
