1·Cobalt ores found in China have a high manganese content, which produces a more muted blue-gray color.
中国发现的钴矿含锰量高，因此呈现出较弱的蓝灰色。
2·They dissolved cobalt and phosphate in water and then zapped it with electricity through an electrode.
他们把钴和磷酸盐溶解到水溶液中，然后，通过电极对它们进行电解。
3·When electricity, whether from photovoltaic cell, wind turbine or other sources, runs through the electrode, the cobalt and phosphate form a thin film on the electrode and oxygen gas is produced.
当电流——无论是来自光伏电池、风轮机还是其它来源——穿过电极时，钴和磷酸盐会在电极上形成一层薄膜，氧气就生成了。
4·It is, after all, not just the Chinese who have been queuing to pay over the odds for those enticing minerals (copper, iron and cobalt) and hydrocarbons.
毕竟，并不仅仅是中国排着队等待着去买那些迷人的矿产资源(铜矿石、铁矿石与钴)和碳氢化合物。
5·Though lithium currently fetches very little on the open market, other components in lithium-ion batteries, such as nickel and cobalt, will make the batteries far too valuable to send to the landfill.
尽管现在锂金属在自由市场很难售出，但是锂离子电池里其他金属元素，例如镍，钴，都非常珍贵，如果把锂离子电池直接送到垃圾场，就太可惜了。
