摘要
从铬的地球化学性状、铬铁矿的形成过程， Al3＋， Fe3＋对 Cr3＋的制约机制及矿石矿物共生组合特征讨论了控制铬铁矿矿石质量的因素，这一研究对评价矿石质量有重要意义。
From the geochemical behaviour of chromium,forming process of chromite,controlling mechanism of Al3＋ ,Fe3＋ on Cr3＋ , and mineral association characteristics of chromite ores, the factors controlling ore quality of chromite are discussed in the paper. It has great significances to valuating quality of ores.
