| 摘 要： | 多金属结核是一种重要的海底矿产资源,其中富含锰、铁、铜、钴、镍等金属。为查明其矿物组成以及其中所含有的有价金属元素的赋存状态,对由广州海洋地质调查局提供的多金属结核样品进行了系统的工艺矿物学研究。研究结果表明,多金属结核中金属元素以锰、铁为主,同时还含有一定量的铜、钴、镍以及钼等有价金属元素。其中锰矿物主要为水羟锰矿,其次为钙锰矿等;铁矿物主要为针铁矿、水针铁矿和纤铁矿。样品中的铜、钴、镍均不以独立矿物的形式存在,钼主要以钼华的形式存在。

| Abstract: | Polymetallic nodule is an important mineral source in the sea bed.It contains a great deal of metal elements such as Mn,Fe,Cu,Co,Ni and so on.In order to know the mineral composition and the occurrence of the all of the valuable metal elements of the polymetallic nodule,the process mineralogy study is carried out on the polymetallic nodule sample which supplied from Guangzhou Marine Geological Survey.The results show that Mn and Fe are the main elements in the ore,and it also contains some other elements such as Cu,Co,Ni and Mo.The main Mn mineral is vernadite,the next main mineral is todorokite.The Fe minerals are goethite,hydro-goethite and lepidocrocite.The elements of Cu,Co and Ni are all not occurring in the form of independent minerals.Mo element occurs in the form of molybdine. |
