; 文献标识码: A Effect of silicon-containing impurity on precipitation of sodium aluminate solution and interaction mechanism WU Zheng-ping, YIN Zhou-lan, CHEN Qi-yuan...: By analyzing the changes of precipitation ratio, particle size and morphology, the effect of the impurity ingredient contained silicon on the process of precipitation of sodium aluminate was studied......
the compounds synthesized in laboratory as the starting materials in the calcium-free oxidative roasting process of chromite ore. The results show that the impurity of ferrous oxide has little effect... further act as the alkali and thus maintain a relatively rapid oxidation rate of trivalent chromium during the whole roasting process of chromite ore. And the impurity of aluminum oxide obviously......
