Abstract

The minerals of the silt of the end of Three Gorges reservoir of Yangtze River were studied. Through the spectral analysis of the samples, the analysis of chemistry components and the content mensuration of main minerals, chemistry components and composition of the main minerals have been tested. The results show that: the silt of Three Gorges of Yangtze River in Chongqing is mainly composed of silicolites and quartz, containing Fe and Ti in small quantity and Yt, Yb and Sc in minim quantity. Main mineral in the silt contain Sc, and average content of Sc in the silt is 6.6g/t. Manufacture of building materials can be made of the trailing and lixiviation dreg by separating Sc from the silt. The silt may be utilized synthetically.
