Given the active growth of emerging technology industries, it has become essential to have large quantities of critical metals to meet the current demand. In the Chilean mining industry, there is a depletion of high-grade mineral ores, and there is hence a need to increase production levels in the copper industry and diversify its market by extracting other elements. One of the strategies is to foster the production of lithium batteries, but the manufacture requires reserves of cobalt (Co) and manganese (Mn). Currently, Co reserves are not being exploited in Chile, and Mn production is almost negligible. This is due to the apparent shortage of high-grade ores on the land surface of the country. Given this scenario, the seabed manganese nodules are presented as a good alternative due to their high average grades of Co and Mn, which in turn would allow the growth of strategic value-added industries including lithium battery production. Chile’s current environmental regulations prevent the exploitation of marine resources. However, given technological advances worldwide, both in collection mechanisms and extractive processes, in addition to the needs generated from the future strategic plans, leads us to think about a project to exploit manganese nodules locally.

智利的锰结核,未来钴和锰生产的替代方法—综述

鉴于新兴技术行业的活跃增长,拥有大量关键金属来满足当前需求已变得至关重要。在智利的采矿业中,高级矿物矿石已经枯竭,因此需要提高铜工业的产量,并通过提取其他元素来使其市场多样化。策略之一是促进锂电池的生产,但制造需要储备钴(Co)和锰(Mn)。目前,智利尚未开采钴储量,而锰的产量几乎可以忽略不计。这是由于该国陆地上的高级矿石明显短缺。在这种情况下,海底锰结核由于具有较高的平均Co和Mn等级,因此被认为是很好的选择。这反过来将使包括锂电池生产在内的战略增值产业得以发展。智利现行的环境法规禁止开采海洋资源。但是,鉴于全球在收集机制和提取工艺方面的技术进步,以及未来战略计划所产生的需求,促使我们考虑在当地开发锰结核的项目。
