WestLB, a fellow-citizen of Düsseldorf, has had to be rescued four times in the past four years after it managed to accumulate a portfolio of 85 billion ($114 billion) of toxic assets that are now worth a fraction of that value.

西德意志银行，杜塞尔多夫的同胞国民，在过去的四年中被救济了四次，因为它好不容易积累的价值850亿欧元（1140亿美元）的不良资产组合，现在只值一丁点儿。

The testing results showed that the optimal reduction conditions are 1320℃ for 120 min and the proportional mass fractions of activated carbon powder and the additive A are 3% and 5%, respectively. The additive A accelerates the aggregation of metallic grains so as to make the enriched metallic grains easier for magnetic separation. The mass fraction of maximum nickel in ferronickel alloy and nickel recovery in the laterite-nickel ore are 8.31% and 95.44%, respectively. Metallic nickel is thus enriched.
