NASA's principal investigator for the rover mission, Steve Squyres, and his colleagues report in the journal Science that the sedimentary rocks analyzed by Opportunity contain sulfate salts and a mineral called jarosite - harsh chemicals that are also found in briny water here on Earth.

此次漫游者任务的主要航天局调查员 Steve Squyres 和他的同伴在《科学日志》上发表道，"机遇号"分析的水成岩物质含有硫酸盐的成分以及一种叫做黄钾铁矾的矿物，这种化学物质具有很强刺激性，在地球的咸海水中也有这种物质。

This paper studies the neutralize agent for zinc hydrometallurgy of jarosite process,analyses advantage and disadvantage of NH_4HCO_3 and calcine as jarosite precipitation neutralize agent,points out if used calcine removed zinc ferrite as neutralize agent,than can cut the cost and reduce zinc content in slag.

研究了湿法炼锌黄钾铁矾渣除铁工艺的中和剂，分析了碳酸氢铵和焙砂作为沉矾中和剂的优缺点，指出用除去铁酸锌的焙砂作中和剂，可降低成本，减少渣含锌。

Jarosite process can obtain high recovery rate of zinc,simultaneously,most of indium remains in the jarosite residues and a little part of indium remains in the high acidities leaching residues.

某锌精矿中铟含量很高，采用黄钾铁矾法处理该高铟锌精矿，在得到较高锌回收率的同时，大部分的铟进入矾渣，少部分进入高浸渣，从矾渣和高浸渣中可回收得到电铟。

The results indicate that both the precipitates produced by Leptospirillum ferriphium strain DY and Acidirhiobacillus ferrooxidans strain GF are composed of jarosite and ammonium jarosite. However, the content of jarosite in the precipitates synthesized by strain GF is 5.53% higher than that synthesized by strain DY, but the content of ammonium jarosite in the precipitates synthesized by strain DY is 15.24% higher than that synthesized by strain GF.

结果表明：无论是嗜铁钩端螺旋菌DY菌株，还是嗜酸氧化亚铁硫杆菌GF菌株合成的沉淀都是黄钾铁矾和黄铵铁矾的混合物；其中，GF合成的沉淀混合物中黄钾铁矾的含量比DY合成的黄钾铁矾约高出5.53%；而DY合成的沉淀中，黄铵铁矾的含量比GF合成的沉淀中的黄铵铁矾的含量约高出15.24%。

The potassium ammonium jarosite with zinc and indium is obtained by Fe3+ ion removal from the iron,zinc and indium coexisted sulphate system by potassium ammonium jarosite process.

在铁、锌、铟共存的硫酸盐体系中采用黄钾铵铁矾法除铁，得到了含锌、铟的黄钾铵铁矾，通过TG/DTA和XRD对黄钾铵铁矾及其热分解产物进行表征。

The strong acidity, Fe(superscript 2+) and rather lower concentration of alkalis ions are responsible for voltaite, not jarosite, crystallizing from the acidic iron-bearing water.

分析认为，废液呈强酸性、溶液中存在大量Fe(上标 2+)、碱金属离子含量偏低是蒸发结晶过程中形成绿钾铁矾而不是黄钾铁矾的主要原因。

The experiment result shows that if Iron in the pickle of copper-smelting smoke ash is removed by Oxygen or oxidation combined with Hydrogen peroxide, Iron removing rate is 90%.

常用除铁方法主要有 [1 ，2 ] ：(1 )直接鼓风氧化生成针铁矿的形式除铁；(2 )用生成磷酸盐沉淀的方法除铁；(3 )用黄钾铁矾法除铁；(4)用过氧化氢氧化除铁；(5 )采用溶剂萃取法分离铁。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
