再次硫化

The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

结果表明：硫化矿的氧化溶解首先是磁黄铁矿，其次是铜的次生硫化矿，再次是黄铜矿，最后是黄铁矿；载金黄铜矿的氧化首先是铁从黄铜矿的晶格中氧化溶解出来，生成中间产物CuS2和CuS；较高的酸度和氯化钠浓度有利于单质硫的生成、三价铁的水解和铜的浸出，进而有利于金浸出率的提高。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
