摘　　要：富钴结壳由于富含Co、Ni、Cu、Mo、Pt、Ti及REE等有价元素,且储量极为丰富,具有巨大的开发潜力,但目前对于这些元素的赋存形式缺乏系统研究,且多认为它们基本都是以类质同象或者吸附态的方式分布于铁锰水合氧化物中。为了深入研究富钴结壳中稀有、稀土元素的赋存状态,利用矿物自动分析系统BPMA在寻找稀散金属方面的优势,找到了富钴结壳中多种未见报道的镍、铜、稀土和钼独立矿物,均呈微细粒包裹于铁锰水合氧化物及其它脉石矿物中,同时辅以化学物相等手段,查清了这些有价元素在各载体矿物中的分布情况。研究结果既丰富了富钴结壳的矿物学内容,也为该类海底沉积资源的开发利用提供依据。该技术方法将为研究类似稀有金属矿床提供借鉴,有望在微观地质研究以及资源精细加工等方面取得广泛应用。Cobalt-rich crusts have great potential for development due to their rich value elements such as Co, Ni, Cu, Mo, Pt, Ti and REE,as well as high resource reserves.However, the current research on the state of these rare and rare earth elements is inadequate, and it is believed that they are basically distributed in ferromanganese hydrated oxides in isomorphism or adsorption state.Making full use of the advantages of mineral automatic analysis system(BPMA) in searching for fine and dispersed metals, a variety of independent minerals in cobalt-rich crusts have been found, which are wrapped in Fe-Mn hydrate oxides and other gangue minerals as fine particles, the distribution of these valuable elements in the carrier minerals was investigated by means of chemical equivalence.This conclusion enriches the mineralogy of cobalt-rich crusts and provides a basis for the exploitation of such seabed resources.At the same time, this technical method also provides reference for the study of similar rare metal deposits, which is expected to be widely used in micro-geological research and fine processing of mineral resources.
