n.硫化鐵礦

This paper deals firstly with the distribution of pyrites in coals. 首先揭示了煤中黃鐵礦的分布賦存規(guī)律。

Its gold content is closely related to pyrites and arsenopyrite. 礦石中的金以不可見金為主,含量與黃鐵礦、毒砂關(guān)系密切。

It's a new-geochemical method,which gold deposits are surveyed with pyrites. 利用黃鐵礦進行找金是一種新的地球化學找礦方法。

An early hypothesis by Chakraborti holds that the arsenic is associated with iron pyrites and enters the aquifers by an oxidation process. 加卡波狄較早提出的一個假說認為，砷與黃鐵礦結(jié)合并透過氧化作用進入含水層。

We utilized the change of concentration ratio between pyrites and rocks to survey gold deposits. 所以通過金在黃鐵礦及巖石中濃度比值的變化，能有效地指導勘查金礦床。
