Presented in this paper are some results of simulating experiments on the geochemical behaviours of iron and aluminium during chilling of silicate meh and on the effect of iron on the behaviours of trace elements U, Mo, Zr, and Ba with a sealed arc apparatus. Experimental results indicate obvious fusing separation of iron and aluminium and their Partial concentration in the silicate melt when the contents of iron and aluminium in the samples are in excess of 4.35%. Furthermore, the effect of fusing separation of iron on the behaviours of trace elements U, Mo, Zr, and Ba is evident. Experimental study has shown that it is possible to avoid iron fusing separation by changing its atomic valence state with the oxidation method. 相似文献
