自然硫

湖南锡矿山锑矿床氧化带的自然硫

Native sulfur in the oxidized zone of the Xikuangshan antimony ore deposit , hunan

第1部分阐述了已熟知的自然硫源？海洋硫循环的了解。

The well-understood natural sulfur cycle in relation to oceanic environment , the well-known natural reservoir , is described in section 1 .

经野外取样和XRD测试技术，在即墨温泉盆地发现硅质沉淀物、盐华、石膏、自然硫等温泉热水沉积指示物。

Based on the XRD data of the field samples , the following hydrothermal sedimentation indicators are discovered : silicious sediment , rock salt , gypsum and natural sulphur .

肃北硫磺矿床矿石中有用矿物为自然硫，硫品位一般在23%～36%。

The useful mineral is natural sulfur in the Subei sulfur deposit , the content of sulfur is generally in 23 % ~ 36 % .

盆内浅凹缓坡带及宽缓低凸起区是寻找自然硫的重要靶区。

The slightly sloping belts of the shallow depressions in basin and slightly low wide convex areas are the important targets in search of native sulfur .

这样没有考虑岩石中自然硫、有机硫和其他形式硫化物存在的影响，且操作烦琐、劳动强度大、成本高。

Therefore , the influence of natural sulphur , organic sulphur and other forms of sulphied matters existing in the rocks are not taken into consideration .

虽然自然硫烟囱体出现在海水环境，但是海水对其不存在铅的贡献，烟囱体内的元素铅主要是陆壳来源。

Although the native sulfur chimney was from seawater , the seawater did not contribute the lead isotopics to the chimney-bearing lead but the continental crust did .

施硫肥可以使水稻获得较好的效益，其中自然硫处理的净产值最高为1882.6元/ha。

The benefits from the application of sulphur fertilizers were very good , and the net income of ES treatment was the highest with 1882.6 RMB yuan / ha .

更糟糕的是，直至最近，中国的很多炼油厂在从原油中提取柴油时，缺少将自然产生的硫污染物除去的技术。

Making matters worse is that , until fairly recently , many Chinese refineries lacked the technology to remove much of the naturally occurring sulfur contaminants when they produced diesel from crude oil .

另外，对新发现的三个罕见矿物（叶碲铋矿、自然铅、锑硫镍矿）的光学性质和化学成分也作了介绍。

In addition , optical properties and chemical composition of newly-discovered three rare mineral ( Pilsenite , Lead , Ullmannite ) are also introduced .
