科学家们经过研究认为,有了海藻的帮忙,海里淘金不再是梦想,可望成为现实。在浩瀚的海洋中,黄金的储藏量十分丰富。据有关专家估计,海洋中储藏的黄金,达1800万吨左右。但是,要从海水中直接提取这些黄金,却是可望而不可及的。因为要从海水中得到1千克黄金,就需处理2亿吨海水,其生产费用,已大大超过了所得的价值。 After research scientists believe that with the help of seaweed, sea gold is no longer a dream, is expected to become a reality. In the vast ocean, gold reserves are very rich. According to the estimation of relevant experts, the gold stored in the oceans reaches about 18 million tons. However, the direct extraction of these gold from seawater is elusive. Because one kilogram of gold needs to be recovered from seawater, 200 million tons of seawater needs to be disposed of, and its production costs have greatly exceeded the value of the proceeds.
