摘要
海底钴结壳富含锰、钴和镍等金属 ,是人类近期勘探和开采研究的热点之一。欲将结壳从海底基岩上剥离并采出海面 ,必要弄清钴结壳的破碎特性。为此采用冲击破碎试验法测定了钴结壳的普氏系数 ,并分析了影响其破碎强度的相关因素 。
Sea-floor cobalt crust is rich in such metals as Mn, Co and Ni, and has been one of recently-exploited and investigeted mineral resources. To strip it from sea-bed rock and transport it to seabank, it is necessary for us to understand the friability of cobalt crust. For this reason, protodrakonov scale of hardness of the cobalt crust is measured by impact crushing test and factors affecting its crushability are analysed, providing the basis for designing crushing devices.
