赤泥中碳硫赋存状态研究

Study on Occurrence State of Carbon and Sulphur in Red Mud

通过对赤泥进行全组分分析及矿物组成分析得出,赤泥中的碳元素主要以独立矿物的形式赋存于方解石、菱铁矿、白云石、铁白云石中。赤泥中硫元素主要以独立矿物的形式赋存于黄铁矿、磁黄铁矿、闪锌矿、黄铜矿中,以类质同象或机械混入的形式赋存于霞石中。其主要载体矿物与赤泥中其他矿物共生关系复杂,相互包裹、连生、夹杂。

Full component anaylysis and mineral composition analysis on red mud has been carried out,the carbon element in red mud is mainly exists in form of independent minerals and occurs in calcite,siderite,dolomite,ankerite.Sulfur element in red mud is mainly exists in form of independent minerals and occurs in pyrite,pyrrhotite,sphalerite,chalcopyrite,or exists in form of isomorphism or mechanical blending form and occurs in epheline.Its host carrier mineral and the other minerals in red mud has complex symbiotic relationship,they are coated in each other,inter growed,mixed together.
