日媒:日本实现全球首次海底矿物大量开采

2017-09-27 09:41:52   

据日媒报道,日本经济产业省与“石油天然气和金属矿物资源机构”(JOGMEC)26日宣布,已实现全球首次成功利用船只大量开采海底矿物资源。

据报道,在日本冲绳县近海,接连发现存在从海底与热水一同喷出的金属堆积而成的“海底热水矿床”,日本力争2020年代中期前后实现商用化。

据了解,海底热水矿床含有锌、铅、金、铜等资源。相关人员今年8月中旬至9月下旬成功实施了试验,利用投入冲绳近海的开采机粉碎海底约1600米的矿床,然后用水泵将其与海水一同抽取上来。据介绍,分析显示此次开采的矿床中存在相当于日本一年用量的锌。

在冲绳近海的专属经济区(EEZ)内,过去三年内发现了6处矿床,今后继续发现新矿床的可能性很高。

日本目前矿物依赖进口,日本经产省期待“确立生产效率高的开采方式。如果能发现足够的蕴藏量,有可能成为资源生产国”。日本经产省计划2018年度实施经济性评估。
